Good morning to the community.
I have an OH3 system on RPI with ZBDongle-E and two SNZB-02Ds.
I easily added your sensors to OH3 and am testing them.
I noticed a different behavior between the two regarding the publication of data in OH3. One of the two publishes the data at a variation of 0.2 °C or every 5-10 minutes (as I expect) while the other publishes the data only if the temperature varies by 1°C or approximately every 2 hours. The behavior of the second doesn’t suit me because that device wants to heat a room by activating/deactivating a radiator.
I searched online and saw that somehow it is possible to adjust the parameters that interest me
Hi, thanks for the information. I did some research and I saw that openhab does not use zigbee2MQTT to manage ZBDongle-E, if I install the zigbeeMQTT program as explained on the site openHABian | Zigbee2MQTT the Tinghs coordinator Ember goes into ERROR. If I don’t install zigbee2mqtt I can’t open the web frontend to set the devices. Can you explain to me how to do it?
Please note that Zigbee2MQTT (Z2M) is an external service which basically has nothing to do with openHAB.
Setting up your Zigbee stick is done through Z2M, not through openHAB, so you can’t use an openHAB Thing for the coordinator
Z2M connects your Zigbee devices through a MQTT Broker and sends their data via the MQTT protocol to openHAB.
That means you will need Z2M, an MQTT broker and the MQTT openHAB binding installed.
Detailed instructions how to connect your Zigbee coordinator to Z2M can be found here:
For the broker, most users here are using Mosquitto broker, installation and setup can be found here:
Check if Z2M and your broker are running correctly, then install the MQTT binding in openHAB and create a Thing for your device. Then add all channels you want to use.
Easiest way to find out which channels are available and on which MQTT topic they are sending data is via a MQTT sniffer, for example MQTT Explorer: http://mqtt-explorer.com/
Installing and setting up all this is not trivial, though …
