Hej

After updating to version 1.9.4 i stopped working. Restart did not solve the problem. Removed and reinstalled hass-ams via hacs with restart between with the same result no entitys is created.

My meter is a swedish Kaifa MA304H4PSE

When i install version 1.9.3 again it works.

From logg file version 1.9.4:

Oh crap... Back to the drawing table. I will draft up a solution. It appears that different meters produce different types of data.

[turbokongen]

Please try this proposed code: https://github.com/turbokongen/hass-AMS/tree/kaifa_se_dual @husky999 @futrax Can you also test, with your meters? The two meters MA304H4 and MA304H4D sendes quite different type of packages.
