Shelly Dimmer 2 shutdown after high temperature event

ha-thomas · December 31, 2023, 12:13pm

Hi HA community,

I have two Shelly dimmers in the living room, each of which supplies 11 LED panels. Each LED light has 9 watts, so 90 watts per dimmer. One dimmer is installed in the flush-mounted box and the other under a drywall ceiling. Both have enough space.
My problem is that the dimmers get too hot and shut off after about 5 minutes when the light is set above 20%.
The temperature then rises above 100 degrees and the dimmer switches off.
I tested various Shelly firmwares, turned on Eco mode, recalibrated and tried all possible settings.

How can I lower the temperature?
Alternatively, I would buy other dimmers if I can’t find a solution.
Do you have a recommendation? I would also have no problem using another manufacturer if necessary.

Greetings

Thomas

Ask shelly?

I already ask Shelly, but they have no idea.

I flashed them with esphome and have a load of around 100W (max) LED connected, in a junction wallbox, no heat issues…

Hello and a happy new year
Thank you for your answer @sender86 .
I have try it with ESPhome, but same issue again.
Temp goes up to 104 degrees at 60 watts.

Any ideas ?
