Shelly makes some very small Wifi relays that work on 12 volts.  This makes it perfect for usage in RVs / Boats / Trucks / Autos.

The software configuration is same for all Shelly relays.

 Depending on how you wire, you should be able to use either the mechanical old switches, or connect myServer 6 control system to control the switches according to time, occupancy, or remotely.

 

Control using myServer

myServer communicates with Shelly devices via MQTT.

Enable MQTT server on myServer in Command Builder.  FYI: Default port is 1883

Add the Shelly Driver to myServer using the Software Updater.

Enable MQTT communication in the Shelly devices's webpage:

  • No SSL
  • Enable MQTT Control
  • Enable RPC over MQTT
  • RPC status notifications over MQTT

Server defined as:  "192.168.0.150:1883"  (or whatever your myServer IP address is)

Relays support On / Off / Toggle commands.  Test these in myServer Command Builder (in the Shelly driver)

Add Shelly devices to myServer by clicking the DISCOVER button in the Shelly myServer driver.

Device type should be "Lighting"

The friendly names you called the relays should come in for ease of identification in myServer.
