I’m using the set_humidity service to set the humidity. The service data looks like:
{"humidity":20}
I would like to add the value of the entity input_number.condensation_offset to the value of 20. Something like:
{"humidity":20+input_number.condensation_offset}
Anyone know what the correct syntax is?
Given you have shown the data as JSON, I’m guessing you’re using Node Red.
If this is the case, you would use a “Current State” node before this one to load the number into the message (say msg.offset), and then use JSONata instead of JSON with the following:
{"humidity": 20+offset }
If you’re not using Node Red and are doing it in an HA automation, you need to use a template
data:
value: "{{ 20 + states('input_number.condensation_offset') | int(0) }}"
Note that you need to convert the offset from a string to a number - I used “int”, but if it should contain decimals, use “float”. I also added a default of 0, so it won’t have a problem if the value is unavailable for some reason.
Thanks! I’m using NodeRed and the Current State node did the trick. I just had to make sure to select “State Type: Number” in the Current State Node.
I have moved your post to the NR category. Please choose the correct category in future to prevent this sort of confusion. Thanks.
{"humidity":20 + $number($entities("input_number.condensation_offset").state)}
