I have installed a Rainbird solenoid valve in my garden. It is switched via a Fibaro double relay with 24vac and the relay is powered with 220vac. I use a button from virtual devices to switch it on and off. It works great.
Questions: (not sure if this should be separated topics as they kind of intertwine within same project)
- the solenoid makes a buzzing sound when turned on. I don’t really hear it because it is softer than the noise from the nearby pomp and the sprinkler. When the solenoid is connected directly to the transformer it made it only a click once when switched. Is that anything to worry about? Could it be that the combination of hard core wire and the relay leak power? The transformer is 0.8 ampere only, but is the official Rainbird brand. I want to add one more solenoid, powered and controlled by the same relay and thus transformator. I have another one of 2.0 ampere. Will that be better or can I risk to burn the solenoids?
- The second solenoid is opening closing flow to my neighbour. We share the pomp and well. We do not use it at the same time. They do not have any domotica. My mesh is good where they want to switch the pomp. What is the best way for them to switch via my domotica without Risk of technical challenges and full access to my system?
- What is the best way to make ad hoc rotations on multiple solenoid valves? I.e. valve 1 on for 2 hours, the closes and valve 2 opens for 3 hours etc.?
