zigbee integration

tomas_hora

@arolli The issue with zigbee is that there are many specifications and not all zigbee radio modules support all of them. So zigbee is not planned right now. You can always use soem USB zigbee module, they work ok.

Thanks Tomas
if i use an zigbee usb module conected to USB how I can configure it in Mervis?

@arolli That is the point... There is no support for Zigbee in Mervis. You would have to use different SW

Thanks Tomas
so if instead of USB adaptor I use a Modbus to Zigbee gateway I can Zigbee with Mervis as a generic Modbus module mapping manually the register.
Do you have any experience with some Zigbee to Modubus gateway?

@arolli One of our customers already did that but I cannot find it...

Hi @tomas_hora,

I wonder whether there is any update on this topic. I am interested in integrating a Patron unit with some ZigBee devices, let's say Phillips Hue and Ikea bulbs. Could you share with us some details on how your customers use ZigBee with Mervis?

Thank you, Martin.

Dear @Peli as far as I know nothing has been done regarding the Mevis&Zigbee topic. As mentioned previously, the easiest way is to use Modbus Zigbee gateway or some USB Zigbee dongle and implement the SW in a different application (Nodered) and tunnel the data to Mervis using Modbus or Bacnet.

Hi @tomas_hora,

Thank you for your answer. I understand that I would need a usb dongle, I found a list of supported devices at zigbee2mqtt.io. Would that be a good list to choose from?

Could you please elaborate on using Node-red or a different application a bit more? Would I be able to use Mervis OS along with node-red? Would they run on the same device (e.g. Axon) or I would need two devices?

Thank you, Martin.

@Peli yes, I have heard that the Conbee, zzh and Slaesh's are quite OK, but have not tried it on my own.

Yes, the Node-red can run on the same device as Mervis, you'll just need to find your own way how to install and run it.

@tomas_hora, thank you.

I have been reading more about your products and I found out that EVOK provides websockets. I was thinking that I would write a script which would process MQTT messages from a dongle and deliver them to Mervis using websocket and the other way around. Would that work? It would replace the Node-red which you suggested.

Thank you for your help, Martin.
