Hi! 
After recent updates I started noticing that the power measurements on my Sonoff POW R1’s have stopped giving any power measurements other than 0.0.
Example:
[13:49:15][D][sensor:118]: 'Socket Washer Wifi Strength': Sending state -73.00000 dBm with 0 decimals of accuracy
[13:49:45][D][sensor:118]: 'Socket Washer Wifi Strength': Sending state -72.00000 dBm with 0 decimals of accuracy
[13:50:15][D][sensor:118]: 'Socket Washer Wifi Strength': Sending state -71.00000 dBm with 0 decimals of accuracy
[13:50:37][D][sensor:118]: 'Socket Washer Power': Sending state 0.00000 W with 1 decimals of accuracy
[13:50:37][D][sensor:118]: 'Socket Washer Energy': Sending state 0.00000 Wh with 3 decimals of accuracy
[13:50:45][D][sensor:118]: 'Socket Washer Wifi Strength': Sending state -72.00000 dBm with 0 decimals of accuracy
[13:51:15][D][sensor:118]: 'Socket Washer Wifi Strength': Sending state -73.00000 dBm with 0 decimals of accuracy
[13:51:37][D][hlw8012:082]: Got power=0.0W, voltage=0.0V

While I’d still need to calibrate them, before they were giving values, even if they weren’t accurate. Accuracy for me is not the main point, it’s mostly to trigger automations based on certain loads.
Other plugs based on the POW R2 using the cse7766 chip seem to have no issues at all.
Am I the only one experiencing this or is there anyone who has tips? Thanks!
