Can't get Commercial Electric T62 downlights to rejoin

🛎️ Get Help
1

I have been having this issue with some downlights (Commercial Electric T62). I have a bunch of those and they have been working fine with Hubitat and then one day I noticed a few of them had disconnected from the network and I couldn't control them anymore. I hard resetted them and Hubitat finds them but they stay 'Initializing' and they never show up in the devices.

I just looked at the log and it's doing weird things:

Note that I only started the discovery once during that log but it looks like it keeps restarting itself. And it looks like it created the devices at some point though they never show up in devices.

I notice in your logs it says Iris Discovery Running, you might want to choose regular Zigbee discovery instead of the Iris V1 zigbee type.

Umm, I had tried the regular Zigbee discovery multiple times before and it did not find the bulbs but it might have been after having tried the Zigbee v1 (Iris) discovery or with the bulbs in some weird state.
I just did a Zigbee discovery after a full reset of the bulbs and it worked this time so I guess problem solved :slight_smile:
Thanks!

I have several commerical electric downlight leds and can not get hubitat to see them. I performed a factory reset on the bulbs, moved my elevation hub closer, but no luck. Did you have to use a specific driver?

I don't use a special driver. I have 34 of them and I have most of them joined on my Hubitat. Only some in a group of 4 are giving me some issues, but those are outside and maybe a little out of range.
Every now and then, the pairing gets lost and I have to reset and rejoin some of them.
Do the bulbs blink after you reset them?

Thanks for the reply.
I have 6 of these installed, they all connect fine to the Hubspace APP. I removed them from the Hubspace APP. I performed the factory reset (3seconds on/off x5) and the bulbs all blink afterwards.
I try to discover using Hubitat add zigbee devices and no devices are found. I tried moving my HE hub closer to the bulbs (next room) with no luck.
In the end, I re-added them to hubspace and that passed the bulbs to Alexa.
I ended up setting up an ERIA dimmer switch in Hubitat and created a virtual switch to pass to Alexa and set up a routine in Alexa based on the HE Virtual switch. Have not been able to get the dimmer yet only on and off. The bulbs turn on/off in a staggered way and sometimes one or more stays on / off.
I am using these bulbs

ah it sounds like you have newer Commercial Electric bulbs and maybe those are not supported by Hubitat and only work with that Hupspace thing (which I don't know anything about). I'm using older T62 bulbs.

well that's unfortunate then, I suppose I will have to live with what I have and make the best of it or buy something else.
