my power is 100% just on the batteries… i have it positioned toward the sun good
it has the option to add a bigger battery box that is included… but the text says it will not charge by built in solar in that configuration which is dumb… i dont understand why
my only complaint is that the units are in metric… the
temp can be switched to F in the app… but thats it
also i wanted total accumulation for the day and seeed has said they are going to add that and wind gust
