AppDaemon does not work at all, even without any app installed

Third party integrations AppDaemon
1

Edit: Tasmota seems to be completely irrelevant here. The problem is, that Appdaemon does not start at all, even without any app.

old:

Is anyone still able to use NSPanel with Tasmota firmware via AppDaemon?
It’s broken for me for >2 months now.

I suspect that AppDaemon has changed something that breaks the communication - but there is no way to downgrade the AddOn, so I’m kinda stuck.

Anyone able to use it properly and how?
Any idea how to fix it?

I’m close to reflashing the NSPanels to esp32 in the hopes to get it to work this way.

I’m using NSPanel on Tasmota (15.0.1) / AppDaemon (0.17.9) / NSPanel Lovelace UI Backend (4.7.4) without problem. In addition, it seems to me that with newer versions, functionality and reliability are better than before.

3

That baffles me.

I had a working setup with 3 NSPanels that stopped working in July.
I have stripped down the apps.yaml to the bare minimum - and I still see a myriad of errors in the AppDaemon log running through.

I have the same versions installed as you mentioned - and I do not see anything that could explain that.

Edit: Maybe I need to throw the whole AppDaemon installation away and start that part from scratch.

I don’t know what to advise. But reinstalling AppDaemon under HA is easy. I would probably start with that. And if that doesn’t help, I would probably try reflashing Tasmota. Since you already have Tasmota there, it’s also easier. I would probably follow the instructions at “Flash Tasmota to your NSPanel”. It’s basically like starting over, but if you save the configuration beforehand, it makes the whole process much easier.

I also use three panels myself, and it really works without any problems. For a while, I wanted to replace the panels with Shelly Wall Display. But after a week, I decided to go back to NSPanel…

5

I already reinstalled AppDaemon and realized that that is the issue because it’s throwing errors even without any app being configured.
Something is screwing up the connection between AppDaemon and HA.

I realized that Tasmota is completely irrelevant and no matter what I do, Appdaemon does not even start without anything at all:

(I tried to play with increased timeouts and retries - but it doesn’t change anything.)

7

Even on a new, dedicated install (with no 3rd party integrations) the addon crashes.
The same happens when I start the instance in a secure mode.

8

It seems that Appdaemon has a limit on how many entities it can handle.
I had >10.000 entities when it crashed.
Now I’m down to 8200 and it works.

9

I think I may be facing the same issue here. I’m curious how you determined this and if you ever found a solution.

Edit to add: I found your comments in AppDaemon 4.5.11 constantly disconnects from HA Core 2025.7.1 with "TypeError: argument of type 'NoneType' is not iterable" · Issue #2399 · AppDaemon/appdaemon · GitHub

10

I found an Integration that had created >3k entities, which pushed me beyond 10k total.

I deleted the entities of that integration and AppDaemon worked again.
I waited a few hours until the entities where back and AD crashed again.
Enteties deleted - worked again and I reconfigured the integration to behave and not spam entities - and AD works ever since.
