Hi there, I am new to Node-RED.
I wanted to create an home automation to notify me when the internal pm2.5 is higher than certain level, say >80 for 30 mins, during day time.
Below is my existing setup (first time posting the code here so I hope it worked). However, I would like to ask the following:
-
How do I improve this automation so that it will announce /notify again after certain time (say 1 hour) if the air quality is still above the threshold?
-
Further from 1), how do I improve it to announce /notify only if the air quality is worse than the previous check?
Thanks a lot.
code:
