RTC lost confidence in the DateTime!
RTC is the same as compile time! (not expected but all is fine)

I finally got this to work. Unlike what the description here says, this is how to update the value:
In Home Assistant, go to Developer->Service->YAML mode:
service: text.set_value
data:
value: "967067"
target:
entity_id: text.water_meter_100_2
(change 967067 with the value you want to add to the current counter)
The service "notify.mysensors" seems to be deprecated by Home Assistant.

I used 3.3V pro mini with regulator removed and powered by Vin pin. Also removed leds from the pro mini.
I used minicore bootloader.
I used the small pir sensors and again removed the regulator to power directly from the pro mini outputs.
After that sleep the node and trigger on interrupt.
Send battery level once a day.
Use inbuilt battery level monitor and not external components that constantly drain power to get battery level.
1.8V is 0% on the graph (not visible yet!) but I have had nodes working below 1.7V It's a matter of luck with that it seems.
Hope this helps you on the right track. I'll try and help if you want.
This is the latest image and still going strong after 18 months. Voltage is at 2.903V
Here is photo of the test example - I need to make a case and produce more of them over winter.....
Here is the same build/code of a window sensor. Similar time frame but hardly triggered.....
bravo and good explanation
good to show that Arduino "8bits" and MySensors can do things simply, without gas factory
an extensible basis for further input/output
(door contact - relay control ...etc )
Thanks
Thank you @JeeLet !
I've been struggling with missing msgs for years with my Arduino Mega
I changed pin and no issues!
In the pjon code I've reached to list of tested pins that communication works properly
