Show an alert if it doesn't rain for x days

Configuration
1

I have some outdoor plants that require water frequently but not too much water. I would like to know if it hasn’t rained for the past 3 days. If the card appears or displays the alert, I want to be able to reset the timer (after I water them) and then the timer begins again.

Any forum threads where someone did something like this? I don’t have a weather station and Dark Sky is no longer available which makes this a bit tricker. Thanks all!

There’s plenty of other weather platforms you can use. not just Dark Sky. Setup another platform to begin with then just use a trigger on the rainfall entity

trigger:
  platform: numeric_state
  entity_id: sensor.your_rainfail_data
  below: 'some valve you want to use'
  for:
    hours: 72

Correct me if I’m wrong but I don’t think the history stats integration can be used to determine a varying numeric value. ie: if an entity has been above or below a setpoint for x time. I think it only works on if an entity is AT a value for x time.

If it hasn’t rained for three days then rainfall has been 0 for that period

Very true. I guess I was thinking of allowing a value greater than 0 to allow some rain.
