Zigbee Channels

[mpx2]

Hello

Are there mandatory channels in Zigbee standard? For example in Metageek's web page it says that "ZigBee channel 26 is usually relatively unaffected by WiFi, but many ZigBee devices do not support it." . Are there differences in US, Europe and Asia like in WiFi channels?

I don’t think there is such regulation in Europe for zigbee channels.

You might find more information here https://github.com/pipiche38/Domoticz-Z ... -Zigbee.md

Which is also pointing to an interesting paper from NXP.

Btw I think livolo switches required channel 26!

Typical output power is 0 dBm. Zigate reports Signal Level and RSSI.

What is Signal Level? Is it signal strength received by sensor or Zigate? Looks like it's not a dB value. RSSI should be signal strength received by Zigate and it looks like dB value.
