OK thanks mfalkvidd

Hi,
I have only one sensor on the mini pro and I have this in the logs:
2017-07-30 14:41:28.492 (Mysensor) Temp (Congélateur)
2017-07-30 14:41:28.497 (Mysensor) Temp (Congélateur)
2017-07-30 14:41:28.501 (Mysensor) Temp (Congélateur)
2017-07-30 14:41:28.506 (Mysensor) Temp (Congélateur)
2017-07-30 14:41:28.510 (Mysensor) Temp (Congélateur)
2017-07-30 14:41:28.515 (Mysensor) Temp (Congélateur)
2017-07-30 14:41:28.521 (Mysensor) Temp (Congélateur)
2017-07-30 14:41:28.526 (Mysensor) Temp (Congélateur)

Sleep time is set to 60000ms, why the time between 2 messages is around 5ms???

Hello,
problem, after each restart of gateway or restore database, all my temp/humity sensors are seen as 2 sensors.
Seen like that:
2017-07-15 15:23:53.758 (Mysensor) Temp (Temp)
2017-07-15 15:23:53.763 (Mysensor) Humidity (Hum)
Should be (on another sensor):
2017-07-15 15:26:45.610 (Mysensor) Temp + Humidity (Salon)

After 3 hours one sensor is still doing the same. I restarted it, no change.
Restarted the gateway again, no change. There is still one sensor which has this behaviour and it's never the same sensor...

@jwosnick: please take a look here: http://www.home-automation-community.com/arduino-low-power-how-to-run-atmega328p-for-a-year-on-coin-cell-battery/.
You'll see that the current saving is significant (almost 40% saving)

Thanx for your answers. @AWI, the BME280 looks great and not expansive i will replace the DHT by this one. Thank you.

Hi,
I would like to use this example and reduce power consumtion by removing the regulator on the mini Pro and the power led.
If we remove the regulator, we can power the board with 3V on Vcc. It will be OK for the mini pro and the NRF but the DHT22 needs 3.3V minimum. The solution will consist to use a step up boost module. What is the current consumtion of the step up boost?
