Have a heater meter with a pi zero ( I think) it worked last time I used it.1 month ago since then i have replaced my router with a mesh system. I'm using the same name and password as the old one .The trouble I'm having is it will not connect to my wifi. When I turn it on it flashes one time code(?) of 20200715B. I tried to look at the sd card but my lap top doesn't like it and wants me to format it. If I try to open it with the file reader a few times it will see the config.txt file but tells me to format it. Out side of that it seems to work ok . There is no ether net port on the HM. Do I need to wipe the sd card and down load the software again? I have a lot of white hair so be gentile with your computer advice. You need t save me again Bryan
