Hi all, I made a function for bathroom ventilation to compare humidity measurements and output a boolean depending on the results. I’m attempting to add 5% on the sensor.home_humidity value to give a little wiggle room for the vent fan activation. However, it’s always sending “true” in debug. What did I miss?
if ("sensor.lumi_lumi_weather_336f0807_humdity" > (5 + "sensor.home_humidity")) {msg.payload = true; }else{ msg.payload=false; } return msg;
Thanks!
Are you sure you want " around the sensor values?
No quotes gives me this error:
ReferenceError: sensor is not defined (line 1, col 1)
well, you did not post the entire flow, so its hard to know if you somehow gathered the sensor values.
Personally I would use a current state node on each sensor and save that in a msg.something values.
Good point. I was only have issues with the function node. Here’s the whole flow:

Ok, you have a bit wrong concept of how a flow works.
If you have two or more connections OUT of a node, then nodes connected to these will get data from the node at the same time, but two or more connections IN to a node will not arrive at the same time. It will be multiple different versions of the flow.
In your example here you will have a flow for when sensor.home_humidity is updated and another for sensor.lumi_lumi_weather_336f0807_humidity. Whenever one sensor is starting a flow the other sensor will be missing and you poll state node will send the sensor state in a msg. variable in the flow, not store it in a sensor. variable.
Try this instead and see what the output is to get the values you need.
