I had a similar idea to what you were mentioning of using a standard solonoid valve and then using a cheaper switch. I am assuming you are meaning something similar to this?
Yes, something like that. Just keep in mind that the maximum water flow of a solenoid valve is less than with a normal valve. So choose one with a big enough diameter.
I just used a simple 24V adapter I had lying around (from an old ethernet switch or something).
Mine is mounted inside so I could use a simple Fibaro wall plug for it.
ok thanks! I will keep that in mind but should be ok for this application and flow shouldn't be an issue. I think I will go down that path it sounds less expensive and I have already had a good experience with the Aeotec Zwave switches.
