AM2315 locked on TEMP value upon weekly restart

SMurphy,

This is the classic problem with the AM2315 and the Raspberry Pi (and others). The I2C on the AM2315 s is flaky and to make it ultra reliable, you need to add a Grove Power Save ( shop.switchdoc.com/products/grovepowersave-control-grove-device-power-with-your-computer-perfect-for-solar-power ) to be able to shut the power off and on in the case of a lock up.

Here is our driver that implements the Grove Power Save:

I suppose it has to do with the fact that while querying the sensor, the device is rebooted and when the PI copmes back, the sensor is locked.
Eventually we have to make sure all sensors are closed bevor initiating the reboot? Didn't check that routine though.

That is a valid point. Question would be why only the temperatur sensor is affected. Humidity worked.
