II am having 2 very weird issues with my smart lights and for the life of me cannot find any reason for why it is happening.

Home assistant with everything up to date
Z2M

Philips hue GU10 smart lights warm white - all firmware updated

  1. (Video attached) Occasionally (maybe once or twice a day, or nothing for a day then multiple times) random lights will start flashing rapidly.
    There is no consistency to the lights that start doing it. Can happen in any of the areas that have the bulbs.
    Randomly happens, it seems if one starts then slowly the other ones start doing it as well. I have left for a few mins and they dont stop.
    Changing the brightness or colour or turning off and on again stops them.

Not sure where to even begin looking. Have reset a couple of the bulbs and reconnected and it has not made a difference

  1. In my office there is 4 of these bulbs, they are setup with an automation to turn off and one to turn on with motion.
    Randomly in a morning, none of the lights will turn on at all. HA triggers it, but even turning off and on at the wall sometimes a couple times does not turn them back on.
    They dont end up turning back on until i take one of them out of the socket and put it back in.

Would appreciate any help and suggestions on how I could start getting to the bottom of this

some kind of undervoltage issue maybe?
or very noisy voltage?
Strange

I’ve only seen this when using smart dimming switches on lights not rated for dimming. Typically goes away by dimming to 100% then dropping to the desired brightness. Or by using bulbs capable of dimming.

I’d wager Antarctica is correct.

Or you are running "off grid" ??? Solar / Fuel / Wind ? ... or "ecoflow like" home inverter ?
Or while charging your tesla ?
I hope it's not a bad connection on breakers, or overloaded circuit ...
May be you can try to move one bulb on another cuircuit/breaker...
You could also use the voltage reported by some smart plugs/ power clamps. Could be interesting .

Yea its so strange.

Its a new apartment build (4 yrs old) with solid electricity in London (at least it seems the electricity is solid).

Its very weird and very random. I had nanoleaf bulbs in before which had their own set of issues (which seems to have been mainly their FW but maybe something with the apartment was playing a factor as well).
There is a dimmer switch on the circuit, but its set to 100% all the time and not touched.

The other one in the office, I have discovered that if I have 3 Hue bulbs in and 1 normal LED bulb, they seem to work fine and do not do the weird thing that stops the circuit working.
But after i replaced the last one so there was 4 in there, in under a couple hours it did the same thing where they go offline in Z2M, and dont turn back on unless I unplug one of them. And it doesnt seem like there is any consistency on what one needs to be unplugged for it to kick them all back on. :S
Even unplugging one so there is 3 Hue and 1 empty bulb slot, seems to do the same problem. This didnt happen wth the 4x zigbee bulbs I tested before or the nanoleaf that were in here, only the Hue ones

I am completely lost at where to go with it.

Here is some even stranger info to add.
When the office lights did this today and went offline today, I turned the dimmer switch all the way to low and they all started flashing and i left it about mid way and they all came back online.

So strange. I logged with Philips but have not had a response from them yet

To use a dimmer with Philips Hue., no sense it makes 🙂

I'd definitely put money on the dimmer switch being the issue.

it could well be the dimmer. try bypassing it.

also, if you have several zigbee bulbs in close proximity it can be interference if you try sending them individual commands simultaneously. i have a lamp with 3 bulbs where they are so close together i have to use a zigbee group. as long as i operate on the group they stay in perfect sync.

Interesting, im guessing a Home assistant group doesnt achieve this? Ill have a look into that.
Some new info I just found when a bunch of lights didnt turn on and z2m had a constant log of MQTT posting over and over and over payloads to the lights and they didtn work till i restarted the addon. So you may be on the right track with the interference, thank you for the comment

If that doesnt help ill see if i can do a dodgy bypass on the dimmer switch. 😄

that counts as using a dimmer

🙂 yeah ender .... 😉

#

even at full trottle .... who knows ....

#

sine wave untuched ... or....

#

and is that a dimmer for incandecent/halogen? or one for fluorescent light? those dimmers behave very differently.

Its a dimmer for led globes.

@glad axle You may be onto the resolution, Since I have set up the zigbee groups, things have seemed to be a lot more consistent! Will need another week to be sure.
