Not sure that this is the correct place to be asking this question but here goes anyway
I have an Emporia Vue 2 which is a really nice piece of kit, well made and reliable.
I do however have a few issues:
Unfortunately they do not make it easy to get local data from the unit as there is no local offload and everything has to be via their cloud server using preferably their phone app.
If you have any connectivity issues it is a big problem as you cannot get any data from the unit.
There is no official API so Home Assistant integration is via a non-official method
There is a restriction on the number of times you can query their server per day which limits the number of 1min interval update calls you can make.
As a result I have been looking for some advice on perhaps reflashing the unit with some alternate firmware that would enable me to send data straight to my MQQT server and not sure if that would even be possible.
Found this video with a close up look at the hardware.

Any suggestions/advice would be appreciated.
Maybe better just to try sell it all and buy some open hardware
