Main instructions

5. RPCs
5
Each ‘setValue’ and ‘getValue’ must be unique.
Two types of RPCs:
Knob (decimal value)
Switch (boolean value)

6. Light Dimm using RPCs in ThingsBoard
Control the light brightness of an AC Lamp using
ThingsBoard RPCs
RPC method: setValue
Range: 0-100.

7. Remotely Controlled RGB using RPCs in
ThingsBoard
Remote control of RGB colors using RPCs in
ThingsBoard.
RPC methods: “setValueRed”, “setValueGreen”
and “setValueBlue”.
Range: 0-255.
