DeepSleep

Currently my setup consumes about 54 mA. So it will consume around 1.3 AH in 24 hours.

Each pump consumes around 1.5 A while running (depending on your pump). Having 2 Pumps with 3 times a day each for 100 seconds adds another 0.25 AH

In total 1.5 AH per day.

It seems that putting the ESP32 in deepsleep mode for most of the time is a good idea. But it has drawbacks.

  1. Tasmota is not able to react to buttons pressed
  2. Flora Beacons are not received anymore
  3. WebUI is not working in deep sleep
  4. Timers are only executed if Tasmota "hears" the clock ticking.
Example:

Think that you put Tasmota to sleep and that it should wake up ever 15 minutes (actually it is at X:00, X:15, X:30 and X:45) You want the first irrigation to happen at 4:00 in the morning.

  • Tasmota wakes up at 4:00 and takes about 25 seconds until it is operational.
  • At that time it will listen to Flora Beacons which are random. To my experience it will take around 3-4 Minutes until all values are received
  • Now you could decide whether to start the pump or not. This means your irrigation timer needs to be at around 4:05
  • If your pump is running for 100 seconds the earliest time Tasmota can go asleep again is 4:08, which I could not make possible because Tasmota can stay awake only for a maximum of 5 minutes
  • This means Tasmota can sleep for 7 minutes only dropping the power consumption to only 0.7 AH
  • And it means that you can change any Tasmota setting only for 8 Minutes every 15 Minutes.
Please decide yourselfe if this is what you want.

I decided to buy a bigger battery and a bigger solar panel to overcome even times where the sun is not shining bright.
