I have a flow that sets temperature for each radiator thermostat. The idea is to lower the temperature on all radiators at bedtime and bring the temp back up again in the morning. I double it, so it also lowers the temp when we are out of the house, but back up again before we come home. So, 2 times down+up at given intervals. I built it like this (flow below):
- a timer node that sends a “start night-lowering”, “end night-lowering”, “start day-lowering” and “end day-lowering” strings.
- for each device (thermostat), I then have a change node, that translates each of the above 4 strings to a value such as { data: { “entity_id”: “climate.kaeldervaerelse”, “temperature”: 21.5 } }
- this value is then passed on to a call service node that identifies the DOMAIN as “Climate” and SERVICE as “set_temperature” - and should then append the above {…} data part and form a succesful call to lower or increase the temperature accordingly.
this has worked flawlessly for years, but now I get the error message:
Call-service error. must contain at least one of temperature, target_temp_high, target_temp_low.
and only this part is the output from the call service node (the Domain and Service parts):
{"domain":"climate","service":"set_temperature"}
so, the data part with the info on what device and what temp, is omitted.
I am really lost. I think it stopped working when I upgraded Node-Red some weeks ago. It appears to me, that the formatting of the data part I am trying to pass from change node to call service node is malformed somehow.
I am not a developer - and am lost, admitted
The flow (I included only one changenode/thermostat (but I have 9) - they all share the same one call service node:
