Not sure if already posted but here's my take on connectivity issues
Fix hypervolt WiFi: or how I learned to stop listening to their support
Have had on/off issues since install in early 2021 which have significantly deteriorated over the last month
Got to a point where I assume the internal timings were completely incorrect, meaning it would only charge between 11:43 and 16:43 - essentially meaning I was unable to charge my car as I was at work!
I couldn't access any settings through the app and even despite siting an access point literally adjacent to the charger it would not connect (this is after 2y of it "sort of" working - intermittently require manual reconnection)
Spoke to support who were earnest but just plain unhelpful - yes funny I have tried turning it on and off and all usual troubleshooting if you read the email I sent you detailing everything.
After manual firmware install hoping that would solve the issue (nope) I got fed up and started looking at running ethernet cable to it (45m run, and very impractical but my only solution)
I took the cover off to inspect the port and how to get it through the glands correctly - and lo and behold hypervolt are using some cheapo usb WiFi adapter. It looks awful, glue coming out of parts of the housing. I know raspberry pi boards have their own so just unplugged it and turned back on - yes onboard is working. Magically it IMMEDIATELY connects without issue to network. I turn off the adjacent WiFi access point and it even connects to my access point inside the house.
I cannot believe how utterly trash their WiFi adapter is and how simple this fix was after so much time.
Posting here in case anyone like me runs across a similar forum - if you have a hypervolt home 2.0 that has WiFi issues I urge you to unplug their crappy usb WiFi adapter.
