Telsa Wall Connector now has error "Failed to connect"

[emptorium]

The problem

Not sure if it's since upgrading to 2025.2.0, had issues with my Tesla Wall Connector integration. All the entities failed to connect around 16 hours ago.

I tried removing the integration, power cycling the actual wall connector, restarting Home Assistant.

Since I removed the integration, the entities are gone. Manually adding the integration with the IP address of the wall connector results in "Failed to connect"

What version of Home Assistant Core has the issue?

core-2025.2.0

What was the last working version of Home Assistant Core?

core.2025.1.4

What type of installation are you running?

Home Assistant Container

Integration causing the issue

Tesla Wall Connector

Are you able to provide more detailed logs, or nmap the device itself to check the device is actually responsive / the problem is clearly homeassistant?

Right now its not really possible to investigate

[emptorium]

Hi there, I was looking for logs but couldn't see anything as the device is no longer successfully integrated? If you have some steps for me to follow, more than happy to fillow them.

The tesla wall connector is working via the tesla app.

I'm having the same issue for around the same amount of time. Getting the following logs: 2025-02-09 09:48:10.789 INFO (MainThread) [backoff] Backing off async_request(...) for 0.1s (tesla_wall_connector.exceptions.WallConnectorConnectionError: Error while communicating with Wall Connector at [redactedIP]: Server disconnected) 2025-02-09 09:48:11.061 INFO (MainThread) [backoff] Backing off async_request(...) for 0.5s (tesla_wall_connector.exceptions.WallConnectorConnectionError: Error while communicating with Wall Connector at [redactedIP]: Server disconnected) 2025-02-09 09:48:11.616 ERROR (MainThread) [backoff] Giving up async_request(...) after 3 tries (tesla_wall_connector.exceptions.WallConnectorConnectionError: Error while communicating with Wall Connector at [redactedIP]: Server disconnected)

I'm experiencing the same issue with identical logs as @KE55ARD. Does this have to do with the tesla change over to the fleet api?

[KE55ARD]

I assumed mine had just dropped off wifi, so rebooted it and connected to it's AP and got a new message saying to download some "Tesla One" app to administer it, which I did and then saw it appeared to be for Tesla staff/partners so didn't seem to be much use. But made me question whether they've changed it's API or something?

[ChucklesR]

Same issue here, same period

[teejmiller]

I also am having the same issue, started happening some time last week. I can confirm the device is accessible on the local network and via the Tesla app.

Giving up async_request(...) after 3 tries (tesla_wall_connector.exceptions.WallConnectorConnectionTimeoutError: Timeout while connecting to Wall Connector at 192.168.xx.xx)

[psujek-dev]

same here - 7.02 HA have data from wallbox, next charging 10.02 integration cant connect to WC.

WallConnector itself have access to internet, I can ping it, working fine with tesla app

[discgolfer74]

I have nothing useful or additional to add, just adding to the "me too"s.

[Gearbot17354]

Having same issue. HA can't connect to the Wall connector. I try deleting it and re adding it back into HA. I just get an error that it Failed to connect.

Wondering the same thing since I also lost the ability for HA to do anything with the TWC....the timing seems about right.

[emptorium]

Always appreciative of the work done related to home assistant, not sure if this integration was created as volunteer work.

It's taken a while to get a response, I'm just glad my integration was more info than depended on for triggering. @einarhauks @CloCkWeRX , can you help?

[slidertom]

I get similar issue: Tesla Wall Connector always receives new IP from DHCP server after router restart. IP can not be static as Orbi does not allow to set static IP's for the guest network. On the other hand Tesla Wall Connector also does not allow to setup static IP address. Would be nice if it would be some automatic scan of network (e.g.: old_ip/24) in case of connection failure to detect the new IP.

[meppss]

Adding myself as "me to" for this issue. Been trying to troubleshoot for the past month or so, no luck.

Confirmed the wall connector is accessible via HTTP, but the integration does not seem to connect anymore.

[sirloinofbeef]

Same issue here :(

[Arturfrain]

Same problem for me

@einarhauks @purcell-lab , can you assist pls? Thx.

@einarhauks @purcell-lab , can you assist pls? Thx.

It has been working rock solid for me, I haven't done anything special with the setup.

[dougat3acres]

It failed for me after its IP address changed. There doesn't appear to be a way to manually change that so I deleted and re-added the integration and everything came back.

Thanks. I wonder what is going on with mine and other's setup? I just upgraded to 2025.4.1 and turned the wall connector on and off. When trying to add the integration, still the same 'Failed to connect' message like everyone else

tried adding back new integration and still getting 'Failed to connect'

[psujek-dev]

mine was working fine, didn't change anything in HA and integration suddenly stop working.

Maybe its relateded to Tesla API - I'm using teslafi.com and they need to change Tesla API on my account to get car telemetry

[KE55ARD]

I upgraded Home Assistant and just started getting this error. IP definitely didn’t change as it’s fixed in my DHCP server.

I believe with Tesla Wall Connector firmware 24.44.0, the local webserver no longer is supported, which breaks this interface I believe.

I have a wall connector with this error and the 24.44.0 firmware.

I also have a wall connector with 24.43.3 which works fine and doesn’t ask me about Tesla One.

I have 24.44.3 firmware so you may be onto something.

[alexeiw123]

I'm failing to connect as well - firmware is 24.44.3

[KE55ARD]

I'm on the same firmware and having this issue.

And suspiciously when I look in the app at the release notes for the wall connector, the latest firmware I can see is from October for 24.36. Almost seems like they didn't want to put up release notes for this version saying "we disabled the local web API, screw you HA users"

[psujek-dev]

Does anyone tried to downgrade firmware ?

[smurmann]

Does anyone tried to downgrade firmware ?

I've tried downgrading the fireware. Sadly I was not successful.
