I am currently building a house and have panels & a battery installed. Most of the time these work fine, but occasionally I have to interrupt the internet connection (for example when electrical work is carried out). When that happens I often have issue with the app not working correctly. This has happened again now, and I am registering only 3 W generation, very occasionally rising to 100W or so. Its a reasonable sort of day here, with some sunny patches, so I'm pretty sure that's an error! I have updated the firmware, but that hasn't fixed the problem. Any suggestions about what I should do next?
