You would think that this would be straightforward but it isn't. Common protocols are:

- Wifi

- Zigbee - this means your bridge has to speak the Zigbee language (see below) the device has to work with it

-- LightLink (EU)

-- Home Automation (US) Note - these two protocols don't play well with each other. It looks like HA is being phased out in favour of LL.

-- Smart Energy

- Z-Wave

Nowadays we have Z-wave Plus which offers various benefits, so make sure any device you have is Plus.

Home Assistant has the following list of compatible USB controllers and OpenHab has this list of USB bindings. The one they share is the Vision Z-Wave USB Stick Gen5 (around EUR 34,-)

- X-Wave

contoller / Smart Hub

The controller runs the bridge devices that each individual vendor brings with their devices. It's a single central place to run all of the devices from.

The absolute Ferrari on controllers is:

Smartthings hub which supports Wifi, Zigbee, Z-Wave at $99, now owned by Samsung

This is the list of compatible devices

As an alternative you can run open source software, which will run on a raspberry pi with a zigbee usb controller.

Bridges are hardware connections.

The HUE bridge has a limit of 50 connections. You can add another bridge to your HUE app, but you will have to switch bridges within the app, which is annoying. You also can't backup your setup.

The Dresden Elektronik Raspbee Premium (SD card image [1]) doesn't have the 50 device limitation and has a backup function. It can be used through the HUE app itself. It also uses deConz software to detect devices. These also support Xiaomi devices.

The husbzb-1 Z-Wave / Zigbee USB device. From [2]

I have husbzb-1. I went out of my way to find out more about this device. I contacted both Nortek and SiliconLabs for help, which is not that helpful.

It turned out that husbzb-1 is mostly a z-wave device. The zigbee is just something the OEM threw in as “added value” and the OEM themselves doesn’t know much about it.

As result, you can expect this thing work well with z-wave.

Zigbee, on the other hand, is a bit tricky.

Much of the tricky part is due to zigbee standard itself. Unlike z-wave, which is practically all-in-one, so as long as there is the word “z-wave”, it should work with each other within a country/region.

Zigbee, on the other hand, by itself doesn’t mean anything from an user’s perspective, because much of compatibility rely on zigbee PLUS some libraries built into the device.

if you have a zigbee device (e.g. light bulb, sensors, etc), you kind of need to know which library that device uses, and you need to make sure your zigbee dongle (husbzb-1) has that built-in as well. These library, though mostly software, can not be added or delete once the device is out of factory.

For our purposes, home automation, there are THREE libraries that may be relevant:

    home automation
    light link
    smart energy

The worse part is that zigbee allow vendor to create their own proprietary library, renders device from that company incompatible with anything else on the market.
The best example of such is Xiaomi. Xiaomi devices are zigbee devices, but they uses proprietary library thus none of xiaomi devices will work with anything else from other companies out of box. Security companies such as ADT probably also uses proprietary zigbee devices so you won’t able to connect your husbzb-1 to their devices directly.

As result, when you buy a zigbee compatible light bulb, for example, you need to know if that bulb uses “light link” profile or “home automation” profile. and you need to compare with that with the dongle(husbzb-1) you have.

And here is the frustration part, being an owner of husbzb-1: the OEM nor Siliconlabs (the maker of zigbee chips inside husbzb-1 dongle) knows for sure what zigbee library does husbzb-1 contains.

The closest answer I have gotten is from Siliconlabs, after I told them which chip and what software stack does this dongle contains (in case you are curious: chip used is Silicon Labs EM3581, and software stack is EmberZNet Pro Release 5.4), the tech support says that it MOST LIKELY include

Home Automation version 1.2

What does it mean?

It means that it is UNLIKELY that zigbee light bulb which uses light link profile would work with husbzb-1 out of box.

And here is where this community comes in: if someone got a light bulb uses standard zigbee light link profile (ikea tradfri… kudos to ikea for using standard profile) and managed to get it to work without ikea hub, then, it means husbzb-1 has light link built in.

if someone got a zigbee smart energy monitor device (many utility company in USA is selling such device at heavy discount to promote energy saving) and managed to get it to work with husbzb-1 out of box, then, it means husbzb-1 also contains “smart energy” profile.

but it means someone has to be willing to take the chance and buy the product and see it connect to husbzb-1 or not.

Smart Lighting

Transforming dumb switches

Busch Jaeger

Busch Jaeger has three switches (rocker, LED dimmer) which will integrate with the HUE bridge. Once you put in a wall insert, you can put different controllers on top of it (one, two or four lane) to control the dumb light. You can then add extra remote control light switches in other location to control the same lights.


File:busch-jaeger-zigbee-light-link.pdf Read the systems manual here

Idealo has the best prices for the dimmers I have found so far. Around EUR 80

Elelabs Zigbee Shield is another raspberry pi addon which works with OpenHab

LED Dimmer

230V Controller Treiber Dimmer Dimmaktor ZIGBEE, kompatibel mit Philips HUE®, Osram Lightify® und IKEA TRÅDFRI® [Energieklasse A++] around EUR 60,-

Philips HUE

It's worth getting a Philips Hue starter Pack with the 2.0 bridge to start you off. NB Philips Hue Lux (only white dimmers) controllers can't control LED lamps with colours, but the full HUE kit can control the white LUX lamps

identifying connected items

To identify lights, click on their name in light setup and they will flash.

To idenfity sensors, click on their name in accessory setup and the LED will flash.

To identify dimmer switches, go to accessory setup and press a button. The last button pressed will be shown under the name of the accessory. I haven't found a way to get the LED to flash yet.

Integrating dumb lights in my smart home

Busch Jaeger will integrate with the HUE bridge

Apparently Friends of Hue will launch a large range of dumb light switches but probably only for Hue bulbs Hue Home Lighting. The partners will be Busch-Jaeger, Feller, Illumra, Niko and Vimar.

Hue also has a motion sensor to trigger the lights. No good for outdoor use. It's very easy to set up but only compatible with Hue lights and won't work with homekit stuff. They are also temperature sensors which you can see in smarthings.

Tips and tricks

When you add lights to a scene, delete the alarm which contains the scene and set it up again. Otherwise not all the lights will always turn on when the alarm goes off.

Use the HUE 1 app for most things, but use the HUE 2 app for the light switches / dimmers. It has more options

The HUE 1 app has support for the Random setting in the alarnms, allowing lights to turn on / off +- up to 30 minutes from the set time. For some reason, Hue2 doesn't have this

Hue restore lets you backup your lights

Hue dimmer

To identify, go to settings, accessory setup in the Hue app. Press a button on the dimmer and in the app you can see which dimmer switch was pressed.

If you can't connect after a power failure / reboot, press all four buttons at once until the green / red light flashes. Resetting the switches by holding down all four buttons until the green light flashed got connectivity back. (Resetting the hub itself didn't do the trick)


at the bottom is a very very good post on how to work this

Screenshot 2018-11-09 Raspberry Pi 3 with zigbee (RaspBee) in Europe.png


These lights don't allow you to change the default on behaviour to last setting in the Hue app, but are a lot cheaper and look good.

They also have a large selection of products advertised to connect with the Osram or Hue brigdes (including a GU10 for EUR 20) shop here

The e14 candle lights are a bit shorter than the Hue candles. A two pack costs around EUR 37 and work well.

Their smart plug works just as well as the Osram one, but is smaller and less obtrusive (it's all white and has no grey bit). They are around EUR 30

The ambience type e27 (white range) looks good and costs EUR 22 Amazon DE.

A double pack of e27 coloured costs EUR 55, also good value Amazon DE

Connection with Hue

In order to connect these lights / accessories to the Hue bridge, you have to have them on, start the search in Hue, turn the power off and then on and the app will find them.

If the smart plug becomes unresponsive, press the button for min 5 seconds and the light will flash blue and then go out. Unplug the smart plug, then put it back in and start the search for new lights in the Hue app. It may take a while. When the light goes red it should be connected properly.


Osram Lightify lights should work very well with the Hue system, as they are both Zigbee. However, both Philips as Osram are being a bit silly in their implementation of the Zigbee protocol, which leads to some strange workarounds.

Smart Plug

These work very well.


  1. start searching for lights in Hue app
  2. plug in the smart plug
  3. It turns up as an on/off plug in Hue

If it isn't found, plug it in closer to the Hue Bridge or a Hue light


Hold the on/off button until you hear a click and the light goes off quickly

If this doesn't work, you can try the 5x5 reset: plug it in for 5 seconds, remove it for 5 seconds, repeat 5 times.

Otherwise remove the light from the bridge.

GU10 lights

Don't use these things, they don't work well with Hue

Currently the GU10 lights are unstable due to Philips Hue updates, which means that all my connected lights won't turn off fully using the Hue controller, after I added 1 new GU10 light.

The plugs work well too, but it could be that they need resetting or touchlink connections before they work. They didn't need an update from the lightify gateway for me. Detect them as a light with the switch set to on (light is green) and they will turn up as an on/off switch.


turn the light or plug off for 3 seconds, turn it on for 3 seconds, repeat 5 times. Leave on and wait (10s). If the light blinks, it has worked, if not, repeat.

connecting to Hue

  1. First you need to upgrade the firmware. If you don't do this, the lights will not go all the way off. This can only be done through the Osram Lightify Gateway (see below).
  2. After the update, unplug the Osram Lightify Gateway entirely, otherwise it will pick up the lights after the reset
  3. reset the light (see above)
  4. turn light OFF
  5. start up Hue app
  6. start searching for lights in Hue app
  7. turn light ON

Note: if the light is already on, the Hue app won't find the light for some reason

  1. profit

Using touchlink

  1. Download the lamp finder jar or File:LampFinder.jar
  2. Plug the lamp / plug close to the Hue bridge (< 30cm away)
  3. start the jar
  4. press the button on the Hue bridge to connect
  5. search for the lamp.


You can do light stealing from the Hue local API. In a web browser go to


where x.x.x.x is your IP address of the hub. This should bring up a web page. Put the light you want to steal within 30cm’s of the hub

You need to URL and/or message body

On my setup this caused the living colours light to flash, I then immediately ran the Connect New lights in the Hue App. Sure enough the Bloom light showed up in the app.

Hope that helps someone else in the future

From here

upgrading Osram Firmware

  1. reset the light
  2. plug in the Lightify gateway
  3. start up the Lightify app
  4. plug in light at as close a distance as possible to the gateway
  5. detect the light using the app (you may have to restart the app, as it doesn't always show that it's detected the light properly)
  6. use the app to update the lights -> you will have to press update a few times before it goes. Once it does go it can take a LONG time. Just wait for the blue line.

troubles with upgrading

The remaining issues I found out to be defective bulbs where they were not updating to the latest Lightify firmware(They are stuck on v1.03.07 and should be on v1.04.12)

My lights are stuck on firmware 1.03.07 according to the Hue app, but the lightify app (connected to a Lightify Gateway) says they are updated to 1.04.12 and can't be updated

Sent back to customer service and replaced.

Bulb types

E27 = screw bulb

GU10 = the little spots with 2 plugs


For lighting you can use many things but the cheapest are:

Cree connected bulb $14.97

GE Link connected LED $14.97

Philips hue white / amazon GBP 14,99

Philips hue white / BOL EUR 19,95 + EUR 1.99 verzending = EUR 21.95

Honeywell Evohome heating


For heating you need a smart radiator valve / TRV (thermostatic radiator valve) / Central heating valve

Conrad has these which are programmable but not smartthings

Honeywell Evohome will be compatible with smartthings soon (they have been saying for years)


Danfoss doesn't seem to work

MiHome has a hack

So far it looks like you will have to connect the brand thermostat to the TRV

Your smart heating package constists of the following:

- TRVs for the radiators

- a thermostat

- a controller / receiver for the CV installation.

The controller / receiver comes in 2 types:

- opentherm: an open standard that allows graduated control over the heat the CV generates

- on / off

When you install your system, you also need a bypass to allow for water to circulate. A possibility is to have one of your radiators on all the time, to act like a bypass.

Honeywell has a 4 zone wifi kit for EUR 483 and for EUR 505

You can buy the receiver seperately for around EUR 100,-

There's also a remote sensing TRV head, for if your radiator is enclosed (in NL they are called Distance Plus)

for around EUR 25

or EUR 59

but I don't know if they are compatible with EvoHome.

Unfortunately the Nefit Ecomline HR line of CVs is on/off only and doesn't have an opentherm adapter. There is an adapter for their own smart thermostat, but you can't use that to connec to the Honeywell Evohome.

evohome controller

The Evohome controller has a maximum of 12 zones. Floor heating needs it's own zone and cannot be combined with a TRV.

system configuration

To get into the installation menu, you need to long press the settings icon. This allows you to configure zones, system devices, system parameters, add zone, system summary, fr comms check and factory reset.

Try to not use spaces in zone names (for graphing)

adding multiple TRVs to a zone

Keep the TRVs physically close to the controller.

After creating the zone, add the first TRV (press button once to see "unbound", long press button until you see "bind", press button until you see "success"). Wait for sync to finish and press the button on the TRV. You should now see the zone name.

It will then ask you to add more sensors. Put them all into binding mode (see above) and THEN press the bind button on the controller. It will add them all silmutaneously. WAIT for syncing to stop and check each TRV to see if they have been added to the zone (press button once) before pressing OK / green tick on the controller.

default temperature sensor when using multiple TRVs in a zone

if it is a zone using multiple HR92, the FIRST one that you bind is sensor and actuator, subsequent HR92s bound are only bound as actuators


if you then go into system parameters, zone parameters

you can change from a single to multiroom zone

this enables every HR92 to be sensor and actuator

rezoning a TRV

See below.

evohome HR92 TRV

rezoning a TRV

To rezone a TRV you need to unbind ALL TRVs from the old AND new zone, destroy the zone on the controller and then rebind. Otherwise things can Go Wrong. Note that the first TRV to connect to a new zone is the one which will measure the temperature, if there are multiple TRVs per zone.

unbind a TRV from a zone

To unbind a bound TRV, first click the button once. It will show the room it is bound to. Now press and hold the button until the display says "bind". (you can also do a RF check from this menu). With "bind" in the display, press and the button. It will say "binding". Press and hold the button. The display will show "cleared". At this point release the button. If you press the button once, it will show "unbound".

Note - if you change the settings on the TRV and under 12 restore to factory settings, this will NOT destroy the binding - it is retained.

bind the TRV

How to bind the HR92 to Evohome controller? First get the evohome controller

Basically press the button once, it will say "unbound". Then press the button for five seconds. The display will say "bind". You should receive a SUCCESS message on the evohome controller(if not go back and re-bind). The name of the allocated zone should appear on the HR92 display when you press the User-added image button.

changing TRV settings

How to change the parameters on the HR92 Wireless Radiator Controller?

To change language, backlight, duration of window function, sensitivity of window function, valve stroke, temperature representation in display, temperature offset, battery type, display of the valve position, window open function and reset to factory settings (NB does not unbind from the zone!) keep the button pressed for five seconds (NB NOT when showing a zone name!). Keep the image button pressed for approximately 5 seconds until Parameter 1 flashes (left-hand digit). The right hand digit shows the current setting. The parameter is displayed additionally in plain text ; for example, the display 1 1 stands for Parameter 1 (language) with Setting 1 (English). Use the adjustment dial to select the desired parameter (left-hand digit). Press the button to edit the parameter. The current setting of the parameter flashes (right-hand digit). Use the adjustment dial to set the desired setting (right-hand digit) and confirm with button. For the further parameters repeat. To exit the menu, select "EXIT" using the adjustment dial and confirm with the button.

Connecting the TRV using an adapter / if the heating stays hot

This happens because the fitting is not compatible. You will need a radiator adapter




Todocontrol has another adapter R453HY012 which you can screw into the TRV as an alternative

about time series dbms

A Time Series DBMS is a database management system that is optimized for handling time series data: each entry is associated with a timestamp.

For example, time series data may be produced by sensors, smart meters or RFIDs in the so-called Internet of Things, or may depict the stock tickers of a high frequency stock trading system.

Time Series DBMS are designed to efficiently collect, store and query various time series with high transaction volumes. Although time series data can be managed with other categories of DBMS (from key-value stores to relational systems), the specific challenges often require specialized systems.
E.g. a query like 'SELECT SENSOR1_CPU_FREQUENCY / SENSOR2_HEAT' joins two time series based on the overlapping areas of time for each and outputs a single composite time series.
