Noisy valves prevent us from turning on before waking up

Who designed this? It is really incredible. These valves are REALLY noisy at night. They wake you up. And wake up my son. So we are not able to turn on radiators before waking up in the morning . Did any of you thought about it? Thanks to netatmo, my house has been extremely cold after the whole night for years because of this. When night mode is on, everything should be turned off. But there's no need to close the radiators!! That way when they turn on in the morning there's no noise. It's incredibly easy to implement this in the app and valves, I'm a programmer myself, I would do it with an API if we could. I would never recommend this to anyone.
