I would like to propose the creation of a PRO HUB that has an ethernet connection, and an external WiFi antenna. Maybe even an SD Card to record data locally when there is an internet outage, and a rechargeable lithium battery for battery backup during a power outage.
if you get any of the may available powerbanks that allow charging while being used (like the one available from weatherflow), you don’t need an sd card or a rechargeable battery. The hub will just continue working and sends the data as soon as the internet is back online.
This is an idea for a PRO version that could possibly have the lithium battery built in so you don’t have an external battery backup unit. The PRO could have an ethernet port and an external antenna wifi so we could avoid upload issues.
