I deployed 5 sensebender nodes just after release in 2015, all with 2 AA batteries from ikea.1 died within a couple of years, because it was placed outdoors. But the rest kept going, and all have been going until this year. So 8 years of battery time on one set of batteries..
I think that is excellent battery life..
I mean the ESP framework version, selected by the board version

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.
