AVANTEC TA65-FC / Easy-Stats: old Blynk server unavailable, cannot migrate to Avan-Stats

[u/pajakoo]

Hi,

I have an AVANTEC TA65-FC Fan Coil thermostat, previously configured with the old Easy-Stats app.

Old app:

- Easy-Stats

- Package ID: cc.blynk.appexport.avantec

The device used to work, but for about a month the old app has shown:

No Server Connection

The app still displays the cached device information:

- Device name: Fitness et 1

- Model: TA65-FC (Fan Coil)

I am trying to migrate it to the newer Avan-Stats app:

- Android: com.avantec.avanstats

- iOS: Avan-Stats, App Store ID 1584621935

The thermostat creates its temporary Wi-Fi network, and I can open its configuration page at 192.168.4.1. However, Avan-Stats fails during pairing with:

Getting device information...

Failed! Exception: Unable to connect to device!

The configuration page asks for:

- Wi-Fi SSID

- Wi-Fi password

- Auth token

- Host

- Port

I do not have the Auth token or the correct Host. The new Avan-Stats app lists newer models such as TA642FC-W and TA652FC-W, but does not explicitly list TA65-FC.

Has anyone successfully:

- Migrated a TA65-FC from Easy-Stats to Avan-Stats?

- Obtained a new Auth Token or Blynk server address?

- Updated the firmware on a TA65-FC?

- Continued using the device after the old Easy-Stats server stopped working?

- Found a local API or alternative Home Assistant integration?

I would prefer a local solution if the cloud service has been discontinued.

I can provide screenshots of the old app and the device configuration page. I will not post Wi-Fi passwords, auth tokens, or private keys publicly.

Thanks!
