That’s a shame as I lost access to the data when Plugwise pulled the server. However I understand the Circles store around 2-3 years of data. It’s a real pity I can’t get access to this data for backup. There’s no way to access the data through the Stretch, as far as I know, as all data was stored on the Plugwise server until it was pulled.
If anyone else knows a way to backup the historic data stored on the Circles please advise as this would be extremely useful.
Just in case you are wondering, I will definitely upgrade this app to be compatible with SDK3 and the new Homey Pro.
I have many circles that I use myself. They are the core of my own home automation.
New version 4.0.1 is ready for testing: Plugwise2py | Homey
This will ensure the compatibility with future Homey versions.
@dcj Many thanks for your kind donation. Much appreciated! 
After 2 weeks i can’t get it working. I filled in my circle mas adresses , let it run for a few hours, i don’t see circles in the web page.

This what i get in the logging.
All the circles are working in Source and also with a Stretch 3.0
I’d like to do a final attempt to add my plugwise circles into Homey pro 2023 via the pw2py app and a raspberry PI with plugwise dongle.
Raspberry Pi 3 Model B Rev 1.2
Operating system 20231012~bullseye (64 bit)
I followed all instructions to set up the pw2py on raspberry , including the config files. No errors reported.
I set the parameters in the app on Homey (IP, mqtt port 1883). Testing MQTT connection gives positive result.
Issues:
the link to browser seems to work, but circles are not available (empty screen). An error occurs: niet beveiligd.
The app on homey gives an error in the logfiler: [ERROR: Url error: [Errno 111] connection refused.
Do you have any suggestions to fix this?
Coffee or beer can be arranged 
Is that caused by an encryption setting maybe? Look at your TLS configuration.

crashing again short after restarting app
SOLVED, resetting the Pi solved the crashing.
new version 4.1.0 is ready for testing: Plugwise2py | Homey
