I am a complete newbie and while searching for possible uses of a Raspberry (I have one Pi 3B running as a DAC with IQAudio) I stumbled on OpenHAB and it was immediately love at first sight.
Apart from the server (I’ll source a Raspberry 4 8Gb) and having decided to adopt a Zigbee Mesh, I am a little confused on the various Zigbee Gateways available.
I have made up my mind on the Phoscon Raspbee II (I believe the Zigbee 3.0 issue will be fixed soon). Is there anything else I can consider not requiring additional hardware to flash?
For the moment I’ll start with two temperature / humidity sensors from XIAOMI to be placed in both bedrooms. The idea is then to play around with Verisure and Netatmo and integrate with radiator valves and then slowly extend.
Any suggestion on Gateways would be more than appreciated.
looks like I’ll have to go for a CC2531 based gateway which is USB. I found this in Amazon that seems to be pre-flashed and works ok:
I am just a tad worried by the fact that it says a maximum of 20 devices, I’d say it is ok as a starting point, before I’ll reach more than 20 sensors I’ll be an OpenHab expert!
The given limits usually refer to Zigbee end devices such as switches or sensors. When you add more routers to the Zigbee mesh (light bulbs act as routers) you can connect more end devices to your mesh network.
The Conbee2 is the USB variant of the Raspee: ConBee II Overview
It has a very good range and works well with openhab via Deconz binding.
