H2 US 3 channel stops responding

I have installed 4 H2 US 3 channel switches.
On install and setup, everything is working great.

All 4 are on different circuits, but i have automations that map them together.

Example, switch one controls a ceiling and a lamp. Switch 2 controls and secrion of ceiling. Switch 3 controls nothing. Switch 4 controls 3 other circuits.

Switch 1, 2, and 3, ive mapped it so the top button will control switch 1 circuit 1, 2nd button circuit 2, and third button switch 2 circuit.
All the status stay the same.

Needless to say, they get pressed quite often throughout the day.

Anyway, randomly, at least one of the switches just stop responding. Doubke click and hold for 5 seconds, nothing. Click 10 times, nothing. No lights on the switches. Ill kill the power, 10 sec, give power, nothing. The lights connected through remain on while power is on the switch. Removing power, they turn off. Add power, they turn back on. So the relays are stuck and the switch is unresponsive.

Ive ordered 5 of these switches and all 5 have had the issue so far. Aqara has replaced each one, but im tired of constantly replacing switches.

They are all driving LED fixtures. 3 on one, 2 on a other, 7 on the final. Id consider a spike to turn them on, but switch 3 that has nothing to it has also died.

I have other smart switches from other companies in the house with no issues. Ive had other smart switches on these exact circuits with no issues.

Any advice on why the H2 US 3 channel keeps dying on me?

Hi, I don’t have the H2 US but I have a question. Is it using Matter or zigbee?
I sometimes have similar issue with Matter connected devices

Theyre all using Thread via the Aqara hub.
I tried with zigbee, but relay reaponse to keep them in sync was way too slow.

That actually sounds more like a firmware or a neutral wire problem than a problem with the LED load. I would look into updating firmware, double check the neutral wire carefully and try disabling automations temporarily to see if freezes occur when automations are not running.

Firmware is fully up to date, 1.0.3.0.

The Neutral has a solid connection on each to the house wiring. Is there a good way for me to confirm the house wiring?

The switches are not just freezing, but fully unresponsive. Unfortunately, its an unknown amount of time for each to go bad. Switch 3(the one with nothing on it) initially went bad within a week, then the next has lasted for multiple months. Id basically have to have no automations for a year to confirm it was the automations

Well, this is unfortunate.

Speaking with support, theyre declaring it as a hardware issue and not replacing the units any further under warranty.

Over 7 units dead within a year.
Circuits have been verified to be correct.
No physical damage to the switches.

Support has stated theyre done troubleshooting and done reaponding.

Now im stuck with dead switches and inability to operate my lights.

I guess I cannot use Aqara, anyone have a suggestion on another brand that can do multi circuit?

Wondering why they don’t change them on warranty?! Where you bought them?

I had ordered 5, theyve replaced 5.
Im still within the 1 year with more dead, but it was stated theyre not replacing anymore.

Ive asked to troubleshoot deeper. They reviewed logs and had be verify the wiring.
They just declared its a hardware issue and theyre done.

I like the product, would love to troubleshoot and validate to make it better.
Just diaappointed all conversations are over

This is crazy. It’s obviously a software issue. They need to update them.

Did you get a refund?!?

I did not get a refund.

Aqara very quickly replaced the first 3 switches under warranty. No troubleshooting beyond showing they were dead.
On the 4th and 5th, I asked to troubleshoot deeper, run tests, manipulate automations.

After a very short time in the world of troubleshooting I get the following from Aqara service
“After five replacements, we have done everything the warranty allows. This will be my final response on this issue.”

No reasoning, no hardware analysis, nothing.

Ive been running 2 for the last 2 months with no automations and have not had any issues.

I kept 2 of the dead ones and plan to trace the electrical to see what component died, but i have not had time to reverse engineer it all, in full, yet.

If anyone from Aqara is reading, im still happy to test, even down to a component level
