Remote QTH needs remote switching
Remotely operated amateur radio stations are becoming more and more common and maybe you have already thought about it.
Sooner or later you will come to the point where you have to switch relays and other things.
Here I have come across a good and inexpensive solution.
Kincony 16 Channel Relay Board – KC868-A16S ESP32 4G Module:
With this board you can switch relay outputs via LAN/WLAN or GSM. Koncony offers its own software for PC and an app. Integration in Tuya, Home Assistant ec is also possible.
Relay outputs 16/32 and more with expansion cards. In addition, there are analog inputs for temperature sensors as well as current and voltage for monitoring purposes.
Here are the relevant links to implement your idea.
