I have a similar problem with devices controlling a very low powered solenoid valve.
First l tried a quality Z-wave switch then a cheap matter over WiFi smart relay. The both work for a while then go offline. I have the power cycle the circuit to get them back on line. They are all close to my hub.
I never considered that the inductive load may be causing the problem.
My next opinions are a WiFi switch or a ZigBee smart relay, based on spare devices that I have.
