Ok so polling is not a cause. As there users had set this to 1s and the whole homey crumbled.
Is your P1 extra powered by an usb adapter? Sometimes it can improve the wifi stability.
Further checking / moving Homey and or access points a bit to improve reach is something to try.
Last night, the ‘Total T1 Usage’ and ‘Total T2 Usage’ values remained unchanged, but the HomeWizard Energy app displayed increased values for both.
P1 v6.0205
HW app v.3.6.61
drop me a diag report please
Nevermind found the problem.

App not restarted
test / beta
v3.6.62
* AbortController code added for APiv2
* Wifi quality capability added (-48dBm is not always clear to users if it is good or bad)
I have the same issue. Has worked without issue for the past 6 months an recently( last weeks) been loosing connection same as you screenshots and only app restart would fix it. So @Jeroen_Tebbens if you need more diagnostic reports for debugging or find simularities in the setup let me know 
, happy to help. And setup is 10s and always has been.
EDIT: was refering to the issue @sschot mentioned on the P1 lossing connection.
Sure drop me a diag report.
Wifi is 100% and within 1 meter, so that can not be the problem and was it also not in the past.
After running test version, till now it is stable.
The P1 is indeed powered by USB from a Powerstrip, so no additional power adapter. But in the months behind us, this was not a problem at all. It is started after you introduced the battery to the app.

But that’s only just the signal strength… it doesn’t say anything about quality and network issues.
This doesn’t solve your issues, but,
my HW P1 seldom loses connection, I’m using it for several years now.
Maybe I’m lucky, maybe my network is configured well.
test/beta @Axel_Aardoom @sschot
v3.6.63
Installed let’s monitor. 
It is running, also the previous beta worked okay. I do inform about the details.
Thank you, pretty sure it should cover the issues since May
No issue untill now👌
Sounds promising.
Could be too close….
Till today no loss anymore
Ok let me push this for certification/ production.
edit: v3.6.63 live now
