The Aqara T1 relay with neutral causes the bulb to flash randomly without any apparent signal source

Cupertino, October 6, 2023

My Aqara T1 relay (with a neutral wire) is configured in a three-way mode. This setup causes the bulb to flash periodically (the relay turns on/off), about every 1 or 2 seconds, with no apparent signal source. This happens sporadically. In the log, I noticed that the relay is receiving off and on signals from an unknown source. I have several relays configured the same way, but this problem only occurs in one room. This relay is about 10 meters away from the switch. I have already tried to fix the problem by replacing the relay, bulb, switch and rechecked the wiring and connection of the switches. Using a tester I determined that there is about 2-5 volts on the wires, apparently from interference The firmware version is 0.0.0_0023 and the Hub M2 version is 4.0.4_0008.0646.
