@plugge thanks for pointing me to use persistent data.
Using a
Shelly Plus 1 PM device (example) and this code your batteries will no longer be charged up to 100% which will hopefully result in a longer battery life.
The code is heavily filled with debugging info.
You can either delete those lines or set debugging to domoticz.LOG_ERROR
Some devices start with high charging rates and these rates drop after a short while.
To prevent inadverted switching off the code eliminates the first data and starts regulating after 3 minutes.
For testing purposes I started with capturing 10 minutes of data.
The code works fine with 8 minutes interval for testing.
Superfluous lines can be deleted.
The time span for comparision and sensibility can be set with this part of the code.
Code: Select all
if domoticz.data.value_8 > 1.33 * domoticz.data.value_0 then
-- switch off shelly like switchoff Groene lampjes
domoticz.devices(CHARGER_SWITCH).switchOff()
end
The full code:

Left line is a device that starts with a high value that drops, right line is a device that charges with a continuous level.
Bugs bug me.
