Hello!
My first post, been looking for a solution to my problem for a while.
I have a non chirp version of the i2c soil moisture sensor (version 2.7.3) from Tindie. When its working, its a great sensor, really pleased with it.
1 problem I just cant get past though is, if the photon resets for whatever reason, power failure, upload of new code, sometimes if I power cycle the power supply, the sensor only ever gives out ‘0’ values for the temperature and light and ‘-1’ for the soil moisture reading.
The only way I have found to get the sensor to reset and give out correct readings is to hot plug the sensor, something the manufacturer does not recommmend.
I wonder what I am doing wrong?
Here is my dreadful code from start to finish, I started adding sensor.resetSensor(); instances all over the place out of desperation to try and kick the sensor back into life.

Apologies if I have uploaded too much code, or have missed some vital info, I would be most grateful for your help and if any more info is required, please let me know.
Thanks.
