At least the ESP 32-c6 and ESP 32-h2 variants have thread and Zigbee radios built in. Just got my ESP32 -c6 development kit. Haven’t had a play yet.
Was thinking of just pretending to the iHost to be a multicolour light or something and following the zigbee 3.0 specs(maybe thread but that looks more complicated), but then thought why not have a DIY mode in the iHOST. Internet stuff can be global but the iHost is just local so you could choose to let local zigbees do DIY.
It is as regards bypassing the eWeLink app, which is what we are talking about. Did I say it was comparable in every aspect or are you building a strawman?
The whole point of a DIY mode would be to bypass the need for “supported clusters”. They would be a private eWeLink DIY cluster. I know they could support clusters, at least in the cluster types they sell devices in, as I said in my very first post and which you clearly did not read.
