I recently installed an Aqara H1 EU (no neutral) wall switch to test it. Works well with ZHA but for the decoupled mode I had to switch to Zigbee2MQTT.
While I got that to work it seems like the switch it losing power/restarting from time to time. I think mostly when I click it and/or the smart light bulb behind the switch is turned on/off. For example an automation turns on the smart light bulb, it stays on for a second or two and then the H1 relay turns everything off and is unresponsive for a moment.
Does anyone know I could fix that? I suspect it might be due to the minimum required W? The switch only controls one single IKEA smart light bulb which does not consume much power…
