I have kitted out my whole house with LightWaveRF switches (“old” ones) which are 433MHz. These are all linked into OH using RFXCOMM and work well.
My next problem to solve is knowing when a human used one of their digits to turn on a light old-school.
One obvious thing is to replace everything with ZWAVE kit but frankly, that is a bit of a stretch considering how much they cost. I also don’t have neutral on most of the lighting circuit.
Options I am playing with:
ESP8266 in the ceiling which is powered off the light circuit. When it reports on (or I can ping it) then it is assumed someone turned the lights on.
Cheapest option for this is Sonoff (£4.30 from BG). Seems overkill for something like this
Frankly, a non-starter. I cannot build my own, case it and make it safe for less money than the Sonoff option
Is there a 433 which is better? It can be run from parasitic power on the lighting circuit.
Downside is knowing when it’s not there any more.
Downside is broadcasting when on, lots of noise and traffic.
I was wondering if anyone had a better option they use?
