Can anyone help me with a S220 automation issue. I have 2 S220 switches one is switching 2 lights and I have set the other which is unwired at the other end of the room to switch on/off at the same time via an automation. This works well as I can control the lights from either switch. But it randomly starts switching both lights on and off every few seconds. The only way to stop this is to switch the automation off. If I enable it again it works fine for a while. Any ideas?
