Hello Piotr!
Well I´ve done fields test and so far the mosfet prevents the uncontrolled battery comsuption, I start the test January 31st and today the batteries still on the 82%
but i get some erratic readings, i think it´s because the batteries, when the MKR FOX 1200 was on the USB this doesn´t happen.
At first i get erratic readings in all the sensors, the 2 Soilwatch 10 and the SEN0148, I split the sensors with 1 transistor for controlling each one, i managed to get normal readings with the SEN0148, but still getting weird readings with the 2 Soilwatchs 10, and I didn´t really know how to solve this problem.
This is what i get in the Sigfox Backend in the messages of my device:
the mapped value it´s a percentage of teh humidity, based on the max adc and the minimum adc. I am using the 3 V Soilwatch version, should i get the 1.1V one ? I don´t know, what is the cause of this readings.
