I have a Multirelay zooz. My water heater is turning on and off on relay 1. This system worked flawlessly for over 5 years. About 6 months ago, I started having trouble using the old-style dashboards to turn the water heater on and off. The C8 pro did turn the water heater on and off every day using Simple Rules, but you could not use a dashboard switch to turn it on or off. Something else that is strange is that the dashboards do show if the water heater is on or not. So you know the buttons are hooked up correctly. I can manually turn the Multirelay relay one on and off by going into the device's menu, Relay 1, and manipulating it there. I became convinced that the C8 Pro must have a problem, so I bought a new one. Installed it and everything worked from Simple Rules and the dashboards. Today, my wife needed the water heater on, so I pulled up the dashboard and clicked on the button that worked 5 days ago. Nothing. I could go to the devices and turn it on there, but what is up with this? How can I turn it on in devices and with simple rules, but the dashboard buttons do not work? Please help
