Astrameter CT not found

[na-am]

What's the issue?

Hi@all

The Marstek App on my iPhone founds no Astrameter CT.
Astrameter is running on the ESP-S3, all ok, that means the Web UI says:

• HME-4 Emulator active
• Powersource is live and shows correct values of the Tibber bridge

and yes, my iPhone is very close to the ESP, but it founds nothing.

any hints would be very appreciated

thx

What exactly did you do in the app? Did you search for a new device over Bluetooth, or open the CT list of your battery?

The emulator won't turn up in a Bluetooth search. marstek_registration adds a CT named AstraMeter CT002 to your Marstek account on first boot. To use it, refresh the CT device list in the battery's settings, or log out and back in. Then switch the battery to automatic mode and select that CT. The CT is shown as offline in that list, which is expected. See Marstek cloud auto-registration and the FAQ.

If AstraMeter CT002 isn't in the list, please post the ESPHome boot logs so we can see whether registration succeeded.

AstraMeter CT002 isn't in your CT list, so the registration didn't go through. Please post the ESPHome log from boot, specifically the lines tagged [marstek_registration]. They show whether the login to eu.hamedata.com worked and whether the device was created.

Also make sure the mailbox and password are the ones for the account your battery is in.

[tomquist]

The ESP already has a MAC saved from an earlier boot (Marstek MAC loaded from prefs: 02b250044ddd), so it doesn't contact Marstek and never creates the CT in your account. Add force_reregister: true and flash again:

  marstek_registration:
    ...
    force_reregister: true

Then post the [marstek_registration] lines from the boot log. After AstraMeter CT002 shows up in the app, remove force_reregister again.
