Eve Thermo cannot be connected via HomeKit Controller

Chase9812 · October 17, 2023, 7:02pm

I have been trying to integrate an Eve Thermo for quite some time.

First, I perform a reset.
Then I add the device in the Eve App, which also works.
Now I delete it again from the Home App.
In HASS (Home Assistant), this is shown to me as a new integration, but as soon as I add it and enter the code, a message appears (the message seems to be missing in your text).

I am running Home Assistant on a Raspberry Pi 4 with the version: Home Assistant 2023.10.3 Supervisor 2023.10.0 Operating System 11.0 Frontend 20231005.0 - latest version

Here is the logfile:

I also don’t know where I could look to see where the Thermo is paired, although I was able to pair it successfully with the Eve App before.

Integrating Eve Thermo depends on the thread network you’re using:

If your border router is HomePod or Apple TV, then I suggest to first pair it with Apple Home, keep it running for a few minutes (check in the Eve app if it’s still connecting via Bluetooth or has already switched to Thread), then remove it from Apple Home and it will appear in HA.

If your border router is not a Apple device (e.g. in my current case a SkyConnect dongle on a Raspi running HA), then you need to pair it in close range to the bluetooth receiver of the hardware you’re running HA on. It will first pair via Bluetooth to then switch to Thread. Only after switching to Thread you may move the Eve Thermo to its “final” destination (and ensure that you have enough thread routers between, e.g. Eve Energy).

I’ve personally switched from Apple HomePod Mini to HA SkyConnect as Open Thread Border Router.

In both cases you should factory reset the Eve Thermo by pressing the small reset button next to the batteries for 10 seconds until the display blinks 66 and 99.

Oh, and I suggest to not upgrade to the Matter firmware any time soon. HA has no UI for commissioning a new device with code, so joining a thread network that is not from Apple but from HA can be a serious challenge and requires directly talking to the websocket of the matter server.

I have both available, the Apple TV and the Sky Connect.

It is paired with the Home App, but I can’t find it in Eve and also I can’t get it added.

In Hasso, however, under Thread my Apple TV and the HomePods are displayed as Border Routers.
I have now paired the Apple TV with Hasso and removed it from the Home App.

Now I have reset the Eve Thermo from factory settings and it is immediately displayed under Hasso as an integration but I can’t pair it, as always
"„Die Kopplung kann nicht durchgeführt werden, da das Gerät nicht mehr gefunden werden kann.“

Now again integrated in the Eve App, set up, and then deleted from Home. However, it had been connected with Thread.
Added the whole thing to Hasso, but again the message comes up:

This accessory is already paired with another device. Reset the accessory and try again.

The Apple TV is linked with Hasso and it is deleted in the Home App.

Under Thread, I get the following display, however, the AppleTV and the HomePods are listed under “Andere Netzwerke” and not at the top.

Do I need to add them here separately? If yes, how do I get the URL of them?

aleco · October 18, 2023, 8:29am

You should be able to set a thread network as “preferred”. Either you use the one created by Apple (MyHome9) or you setup SkyConnect to use it as thread border router. But choose one of the paths and then integrate everything in that network. Multiple thread networks don’t talk to each other, so a device in thread network A will not be seen if HAs preferred network is B.

Here’s how it looks in my case:

PS: During the time when I migrated all my devices to the SkyConnect thread network I turned off my HomePod to ensure that there’s only a single thread network available. And in case you choose to use the Apple thread network, you can unplug the SkyConnect dongle, as you won’t need it (or you’ll use it for Zigbee).

Chase9812 · October 18, 2023, 5:54pm

From what I understood, the HomePod or Apple TV will not appear under preferred networks. At least that’s what I read in another forum.

However, the problem remains that I can’t get my Eve Thermo into Home Assistant. I can see and connect to it, but I always get a message saying that the system is already connected, which isn’t the case.

daniel-mller-87 · November 11, 2023, 8:11pm

did you manage now? It’s the same error for me.

aleco · November 17, 2023, 8:59am

For Eve Thermo it’s not enough to just remove them from the Apple HomeKit network. You need to reset the device by pressing the button(s?) next to the batteries for about 10 seconds until you see 66/99 blinking on the display. Then you can add them to a different network (but probably you’ll first add them via a bluetooth connection, close to your HA server or bt antenna).

Peter_Westerlund · January 9, 2024, 7:18pm

I did that, and could add Eve Thermo to HA. But could then not use it in HA. And got “Err” on the display.
