I really think that , to make sense, the latching solenoids should be operated on batteries.
Otherwise the additional cost , complexity and the lower reliability versus 24v Ac it is not justifiable.
In my case using Lipo batteries the charging current is not a problem and there is also the simple and cheap solution to use a 9v or 12v batteries for the solenoid and a separate one for the Esp.
