We have noticed that if our solar powered sensors fail for an extended time period (several hours) the wittypi will not recover and resume power management operations. We believe this is due to the way we have out schedule script set up. We are powered on for14 minutes and off for one minute (we manually shut down the sensor after telemetry. The fourteen minute on period is set as a fail safe incase the modem locks up). Is there another what to set up this script that would auto restore after the power cell has sufficient charge?
If you are powering your device with battery (feed Witty Pi voltage via VIN, or the white connector, instead of the USB-C connector), and if you want the device to automatically boot up when the bettery voltage raised to certain level, you may configure the low voltage threshold and recovery voltage threshold (search in the user manual for details).
No picture, no log, no schedule script file...... with just a short description like this, nobody can guess what actually happend, and hence nobody can give better advice. If you want to get better support, please read forum rules first and provide more information.
