Anyone knows of an existing hubs for 433 mhz devices, like wall switches, sockets etc? I mean I could build one easily enough with a raspi etc, but an existing one would be handy. I found one that looks nice but it's not on amazon UK.
Can you use the Echo dot, with Harmony Hub, to change channels on the TV by saying, "Alexa, turn over to BBC1" etc?
if so how?
According to the Harmony app you have to say something like, "Alexa, tell Harmony to turn on BBC1"
Thanks in advance...
