Is Konke limited channels an issue if using zigbee2mqtt

Hi. First many thanks to Koenkk for creating and sharing this software. I’ve successfully flash both coordinator and router firmware and installed zigbee2mqtt under Docker with Domoticz.

I’m now looking for devices starting with motion sensors. It seems to me starting with HA at this point in time I should go for zigbee 3.0 devices though it’s hard work finding such devices to purchase - the Zigbee Alliance site only lists 7, most cannot be found on shopping sites (maybe not yet to market) and most online shops lack model nos and zigbee version.

I note that Konke make a 3.0 motion sensor but I have a couple of questions:

  1. Is Konke limited channels an issue if using zigbee2mqtt?

  2. Is the model 2AJZ4KPBS on the Supported Devices page the same as this one on the banggood site

I need 4, so affordability and longevity is important (I know that could be a contradiction :wink:

Thanks for reading
Alan
