On/Off of a Fibaro relay device, only through a scene.

Hi, 

Is there a way to lock the relay operation for changes coming directly from the app/gui, and allow them only through scenes?

The rational is not allowing any state change before doing some checks. I have two dosing pumps feed my pool with chlorine & acid and I don't want to allow one of them to start if the other one is working. A mistakenly 'on' pressing directly on the device itself, in the app or gui, can be harmful.

If a complete lock isn't possible, maybe there's a pin protected operation option?

 

Any idea?

 

Thanks!

You can achieve this by hiding the device from being displayed. Click the "device is hidden in the system" checkbox (or similar name) in the device tab, you need to do for master and slaves.

You could try to disable functions, but you could also prevent a situation to happen. 
 

You could make two scenes, triggered by each pomp, so if one goes on, the other goes off and the other scene the other way around. On the HC2 you could also use a magic scene for that. 
 

I have a Fan with two levels. I don’t want to both to be on and solved it with the scenes.
