this morning the test node died… for real 
so yes I finished the rocketscream lowpower node test
result : 290 days on a single AA battery transmitting temp / framecounter / humidity every 5 min.
but that test was done with a BME280 sensor
the node died when the voltage dropped to 1.17 V last night
the V2 version (the one that’s available now, will even last a bit longer)
