No devices showing in Web UI after Z2M update

[basvdploeg]

What happened?

After updating from 2.1.0-1 to 2.1.3-1, all devices disappeared from the Web UI. Also no logs are available from the web interface.

Note: The devices are still working fine and are still controllable via Home Assistant. The add-on log shows no errors and displays all device updates like normal.

When I revert back to a 2.1.0-1 backup, all devices show up immediately again.

What did you expect to happen?

Show all my devices in the Web UI.

Same, but: only 3 devices in web ui...of 30...but all still working...downgraded to 2.1.1 ...not solved problem...still 3 devices...

@Hotabka I doubt that’s same issue.

My Web UI isn’t showing devices or logs at all.

Just restarted HA, all devices back in WebUI

[basvdploeg]

Yeah, that’s not working here. So clearly a different problem.

Did you try uninstalling/reinstalling the HA add-on?
Also make sure you are not seeing a weird browser caching issue with frontend (clear cache/cookies).

@Nerivec I just reinstalled the add-on. The results are the same. As soon as version 2.1.3-1 is installed, the devices In the UI are gone.

When I revert back to 2.1.0-1, they show up immediately again.

(About > Stats also doesn’t show any devices.)

And other pages of frontend have data? Like the top of About?

@Nerivec The top of About is showing up fine. I've made some comparisons screenshots between the two versions:
