## **MQTT commands** All commands must be written as `{"cmd": ,"data":, "id":}`. The `id` can be replaced with `hc` for some devices that use heating circuits, and represented either as a string or a number. `cmd` is a string, `data` can be a string or number. topic = *boiler_cmd* ``` comfort flowtemp wwtemp boilhyston (negative value) boilhystoff (positive value) burnperiod burnminpower <%> burnmaxpower <%> pumpdelay ``` topic = *thermostat_cmd* ``` --- without hc --- wwmode calinttemp minexttemp building language (0=de, 1=nl, 2=fr, 3=it) only RC30 display (0=int temp, 1= int set, 2=ext. temp, 3=burner, 4=ww, 5=mode, 6=time, 7=date, 8=smoke) only RC30 clockoffset (only RC30) --- with hc --- mode temp nighttemp daytemp nofrosttemp ecotemp heattemp summertemp designtemp offsettemp holidaytemp remotetemp control <0 | 1 | 2> pause party holiday date ``` topic = *system_cmd* ``` send <"0B XX XX .."> pin ```
