There really needs to be a webpage with current device types that work with Tasmota.
Same is true of Matter supported device types.
And possibly a page for both: eg. Which devices that connect to the iHost via Tasmota are bridged by the iHost to matter.
Not sure how much Bluetooth connections are allowed. Seen the Bluetooth speakers in the Pilot options. Suggests the iHost can Bluetooth pair. I think the tasmota integration works via MQTT on wifi. I don’t even know if MQTT can be sent over Bluetooth. Would need to look it up.
Incidentally, if you’ve already got tasmota on them you could control the tasmota using the MQTT on Node Red and then create a virtual device on Node Red to replicate the tasmota. It’s a PITA but doable.
