Use a Arduino-compatible mikrocontroller like a WEMOS D1 Mini or any other ESP module to get and set values on a Wamsler / Westminster Pellet stove.
Example:
/usr/bin/curl [STOVE-IP]/get?ct will print the current ambient temperature.
/usr/bin/curl [STOVE-IP]/set?tt=22 will set the target temperature to 22°C.
Possible to set:
- tt -> target temperature
- pl -> power level (0 = off)
- on / off
Possible to get:
- tt -> target temperature
- ct -> current ambient temperature
- pl -> power level
- sb -> state binary (on = true, off = false)
- s -> state verbal
Example for home-assistant:
Get ambient temperature
sensor:
- platform: command_line
name: "stove current abmient temperature
command: "/usr/bin/curl [STOVE-IP]/get?ct"
unit_of_measurement: "°C"
scan_interval: 60
set target temperature
rest_command:
set_t_temp:
url: "http://[STOVE-IP]/set?tt={{ states('input_number.slider_stove_target_temp') }}"
