I think the problem is that Storm Watch was never turned on by Tesla for
@shs1 in this storm. I've had Storm Watch enabled in the app since it was first added. We've had many National Weather Service alerts but Storm Watch hasn't ever kicked in. Not only have I not been able to charge my Powerwalls from the grid, but I've actually seen them sending power
to the grid during a snowstorm.
When yours worked, was it due to severe winds? So far, I don't think we've seen anyone reporting it is activated due to severe snow storms.
