Finally I am buying a Meross MTS215BMA with Matter. But what I don’t know is if I will need any antena for Threads to connect to my RPi with home assistant? or maybe this thermostat works with Matter over wifi. Do you guys think if I go with smart devices connected via Matter (I have seen most Ikea smart home devices support it), do I need a Threads hub/antena? If so, any recomendation?
