I'm relatively new to Node-Red and I've been coming up short trying to put together a reliable flow to notify me when the VPD in my tent is out of the range I'd like it to stay in.
Hopefully I've added my flow info correctly so it can be looked at. In this flow I'm controlling the VPD of my grow tent by reading ambient temp, leaf temp, and humidity and then adjusting humidity to get me to the correct VPD range. I'm looking to make a flow that will notify me if the VPD value is ± 0.1 kPa for longer than a certain amount of time.
You can see in the flow that I started putting something together, but it wasn't working the way I expected. I'm at a bit of a loss so hopefully some nice folks around these parts can help me out.
TIA!
