At a time when several vendors of smart plugs and switches are locking down their firmware, TopGreener still allows reflashing with Tasmota which made it easy to integrate into my Home Assistant system. The tasmota template is the same as their TGWF115APM and I have submitted it for inclusion.The size and shape allows two of them to be plugged into the same outlet.I'm not going to use it with Alexa so I couldn't comment on that feature and I don't know why is asking me to rate the "warmth" of the product :-)
