2026.3 Beta week

A general reminder: Beta week is not designed to fully overhaul a new feature, but to identify bugs that may be introduced with the update.

If you have an issue, please let us know here! However, the developers are very active in the #beta channel of our Discord server during Beta - it’s good to hop in there if you can. To ensure things are addressed in a timely manner, be sure to also submit issues on GitHub in their proper space:

Here are this month’s Beta notes!

I don’t have a Discord account, so I’ll just post it here: fullscreen mode in the code editor doesn’t work, making the popup smaller, as shown in the screenshot below. I cleared the cache and restarted.

I brought it up on discord, will let you know how it develops. It actually works fine in dev tools template editor and in automation creation… it’s just cards.

Edit: Opened and issue

Likely related to #749, not sure if it made it into b1 though.

Indeed, bug filed with dwd_weather

nice


Anyone else got this error in the energy dashboard?


It´s a black screen with only this error.

I get those from time to time after an update on odd screens, reloading takes care of it for me.

Fixedin b2

I just updated to b2, didn´t change. Reloading or restarting either. No logs about this in core.

You should open an issue in HA’s frontend repository for this then.

you mean this

dwd_weather fixed now (in 3v.0.3 for me)
