Could have been a diyer on here, or it could have been sarcasm
Talking of sarcasm......
The market is flooded with loads of products it is quite hard to decide what to buy, I have a mixture of the most expensive and cheaper kit. RF lightwave (expensive) only seem to do dimmer lights for some reason, which makes them even more expensive when you want LED lights everywhere. Broadlink one of the cheapest is very innovative, their lightswitch doesnt require a negative to work, the broadlink controller has ir as well as radio and WiFi which means you can control Tv Hifi and just about anything that has ir including my aircon at work, the sw has a 7 day timer so I can program the heating to start 10 mins before I arrive at work and I can switch it off from my phone or Alexa of course if I am not going to be in.
