I in hind sight made an error, the light was large enough to take the relay
View attachment 297272 so I put the relay
View attachment 297273 in the lamp, but the lamp is not easy to assess
View attachment 297274 so when the relay started to play up, it was too big of a job to access it again, it works A1 with the zigbee, but it should also work with the light switch, and this is intermittent, some days it will, some days it will not, but saying hey google turn on landing lights always works so not that worried.
However learn from my error, put the relay where you can assess it.
The other thing is it is seen as a relay not a light, with bulbs we can program a remote control to work them, but it does not work with the relay. Also general commands like hey google turn off all lights does not turn it off, as not seen as a light.
It also does not dim the lights, I have found bulbs vary a lot in what they can do, the Wiz bulb can be programmed to fade out first when switched off, I find this good as not suddenly plunged into darkness, however it does not seem to have a timed off, the other bulbs all have timers built in, so outside lights have two off times, so if I forget to turn them off the turn off anyway twice a day, not all the same time, so not plunged into darkness.
Wife seems to be loosing use of fingers now, what did you say love, gets answer I was talking to google not you. Yes getting into bed or out of bed and using a remote or voice to turn lights on/off is good. But not so sure with living room lights, I just get lazy, and sit with just cabinet lights on, as they have voice control. The stairs light shown yes good with two cups of coffee one in each hand to be able to turn on lights. Mainly as the light switch is not at bottom of stairs but other end of hall.
However with smart bulbs there is no need to rewire, and in hind sight would have been better to use 5 smart bulbs instead of relay. Centre one is smart anyway so I can get nice effects
View attachment 297276 so not so sure really needed a relay, the advantage should have been with relay the existing light switches switch lights in same way as two way switches, change state of switch, and light changes state, but switches don't always work, and need to remember switches now extra low voltage not at low voltage (mains).
As said though if had to do it again I would simply use smart bulbs.
