They do mine once a year ....although if it needs be they give me the option to adjust it again in June .....they only read the meter twice a year ...
I enter mine every month on line and they have checked it once in three years
I don't know how they haven't wanted to be in your house for a company read one They do with me. They only let me have so many customer readings
ours are outside and we have to do our own - not had it read manually for years
