One question: I installed dimmer 2 because I tried Shelly 1L before and it didn't work. There are 4 Led equipments with individual transformer each.
If this overheating problem is not solved, can you think of another solution from this manufacturer for me? Thanks
I have recalibrated, I have changed the intensity in multiples of ten ... it always jumps.
Would the situation improve by incorporating a bypass? By quantity of consumption it does not seem necessary, but this error is terrible. And it is affecting me in the most attractive circuit of the house of some clients, I cannot fail in this matter.
Alles anzeigenHello,
in these days I tried everything.
I set Trailing edge. I repeated calibration a lot of times.
I downgraded firmware to 1.9.0. I upgraded to beta firmware 1.10.2.
But the result is always exactly the same.
After a while with lights on at 100%, the "shelly dimmer 2" with 9 leds (~70W load) becomes hotter and hotter, and when its temperature raises to ~105°C it switches off with overtemperature error.
First time it happens after about 10-15 minutes of activity. Then, if I switch it on again when it's still quite hot, it lasts less.
No problem with the other "dimmer 2" with 6 leds (~43W load): it becomes a bit hot (about 95°C) but then it keeps stable.
As stated before, I tried swapping them, so it's not a matter of a defective unit.
I don't understand why the shelly dimmers become so hot.
My previous simple shelly 1's never gave me problems.
If I keep open the electric box where the shellys are installed, the dimmer with 9 leds does not become so much hot, and it seems stable. However for obvious reasons I cannot keep it open.
I'm sad... If I don't find a solution soon, I think I'll have to return the shellies...
I have the same problem. with 4 LED equipments totaling 36 w. All devices are the same. After 1 minute it heats up and turns off.
The firmware is 1.10.1, and the calibration is in "Trailing edge" mode. With the "autodetect type of load during calibration" checkbox checked.
Thanks for your help
