Hello,
i think i solved it. For the community here my Solution. In the future i will provide a description about the hole setup.
The HA UI that i use is this:
The esp32 wakes up after the set sleep time and is doing this:
- measuring the moisture and sending the value to HA
- If its under the set Threshold it pumps for 10s
- Sending the last time pumped to HA
- If pumped it goes just for a few minutes to deep sleep
- Check if it is allowed to go to deep sleep (I have this to be able to update the code)
- Only if no pumping is needed it goes to the set duration into deep sleep
In HA i had to make two input.number for the moisture threshold and the Sleep time duration, as well as one input.boolean for the prevention of deep sleep.
The code for the esp32 ist here:
Note: i commented the interesting parts that where complicated.

Following problems that i struggled with i solved here:
- the “on_value_range” command only triggers when the new value is inside the range and the previous value was outside the range. With this it didnt triggered the pumping if the value was still under the threshold. So i used the “on-value” and if condition.
- Becuse of the excessive use of deep_sleep for battery saving reasons, often on booting the script had the measured moisture value but dont had the threshold value from HA and went to completly strange conditions. For this i build an if condition to just check the threshold value if its available. (I think i abused it a bit.
)
The part of the code that iam talking about is this:
on_value:
then:
- if:
condition: #check that the threshold value from HA UI is imported
sensor.in_range:
id: moisture_set
below: 100.0
then:
- if:
condition: #compare value from sensor with threshold value, it is more complicated that "on_range" bcs it also triggers now when the value didnt changed
lambda: 'return id(moisturesensor).state < id(moisture_set).state;'
So this is my walk of pain to this solution. I hope it helps further anonymus masochists in the future.
As i mentioned i will make a post in the future about the hole project with Part list and how it is set up in my plants.
