@dbemowsk this can be crudely done via routine feature on amazon alexa, what it offers is that you can rename any IOT device state (ON or OFF) with any name, so like in your example, living room lights you can just say Alexa "living room overheads" and it will turn the living room overhead lights, similarly for office you can say "Alexa; "office overheads" and it will switch on the office overhead lights. Ofcouse you have to have a different phrase for OFF state, but you get the idea. But yes the same phrase for all rooms and letting alexa sense which room r u in, and acting accordingly is actual smart home. I would keep searching if I can find n build somethig like that.

@dbemowsk Do you know if there is a way to use vera edge / plus with Tasmota firmware instead of EasyESP??
