I am starting a new topic to explain the situation I am facing with a Sonoff TX T2 EU switch. I will just copy and paste the information needed, I had everything sent in an email but unfortunately after writing the same things 4 times, the person(s) replying could not understand simple English to be able to answer properly. So here is the original text.
I have 9x TX T2 EU 1 gang switches in my house and 1x TX T2 EU 2 gang. The switches supply power converters - led drivers that provide 24V to 24V led strips. All my switches work fine since the day I purchased them, except for 1 switch with which I have a constant problem. A few hours after the installed switch is supplied with power it freezes, it does not respond to touch and it appears offline. If I cut off the power to this switch, it starts working, it appears online in the app again but after some hours (I have measured from 1 to 22 hours in different cases) it freezes and goes offline again. I cannot turn on and off the lights when the switch is frozen. Please note, this is not a contact problem, as the switch appears offline after it freezes. The freezing, the unresponsiveness to touch and the offline status is something that happens at the same moment. There has been no case that the switch was responsive to touch but offline or frozen, or that the switch was unresponsive to touch but online. When the switch crashes, everything stops working. I have no other way to reset the switch, so I am forced to turn off the fuse to restart the switch. After I restore the power, the switch is fully functional and online until this problem reappears, then it freezes, becomes unresponsive to touch and goes offline.
Now the first thought for an outsider might be that it is a malfunctioning switch. Well, this is not the case. I had the switch replaced because it was under warranty. I received a replacement. The problem remains. I also thought of replacing the power converter behind the switch, in case it is malfunctioning and causes problems to the switch. No change. I replaced the Sonoff switch AND the power converter, the problem is still there and exactly the same.
The switch remains in this frozen condition no matter how many days pass. The only way to recover it, is to cut off the power.
I need someone who might know WHAT can cause this behavior, like a technician.
I have some videos to show this problem.
After cutting off the power and restoring it, switch is fine, responsive, online and working.
Some hours later, the switch is frozen. The square light is on, so is the wifi light. But the switch is unresponsive to touch and offline. The log shows nothing at all.
I have tried everything possible to my knowledge to solve this problem. I even replaced the switch and the led driver after it. I even let the switch disconnected from the led driver to see if something causes this problem. The switch behaves same way even if its alone there controlling nothing at all.
I have written to support since mid January. It is very slow and I have to explain things 4-5 times and still they fail to understand. Anybody with a recommendation?
Any help will be appreciated.
