Sonoff TH01 temperature and humidity sensor is one of the most stable T/H sensors that I have... It fully complies with Zigbee standards and can be configured to send updates as fast as every 10 seconds on 0.1 deg change ..
Try this driver, we can see some additional statistics after few days:
Here the hub has received 32 thousands reports in the last few months (because of the frequent reporting settings that I have configured), and the device has rejoined the ZIgbee network only 6 times. This includes the rejoins when the C-8 hub has been shut down for a longer period.
