No. I had no more time to spend on this issue right now. Tellmon is a hobby-project that competes with my regular job and time to spend with my family. Did Telldus respond anything?

No. All I can see is that Tellmon gets a "403 forbidden" from api.telldus.com when trying to access your devices with your token. Works for me and, as far as I know, all other users.

The email-address you are using is that the ola.xxxxx@hotmail.com one?

Yes. And that's what is so strange. The login authentication is also handled by Telldus. So first they say your username and password is ok and issues a OATH token for tellmon to use. Then they return 403 error when Tellmon tries to use that token to access your devices.

I even tried deleting my own account and that came back just fine. So I'm pretty sure the issue is at Telldus and related to you changing your email. 

1. Can you login and use http://live.telldus.com ?
2. Can you login to this address: https://api.telldus.com/explore/index
   - Then click "clients/list" on the top of the left side menu
   - Then change to "json" and click "send".

This is the same that Tellmon does and it might identify the problem if it does not work.

Your email that you use to login now, what is it?

Unfortunately I've got nothing in the errors logs. But I'll try do debug a bit and see if I can send you some errors.

Can you try again and note the exact time you tried? I'll need that to identify any logged errors coming from you.

No, that should be sufficient. It must be somehow connected to you changing the email at Telldus. Can you rise a support ticket at Telldus? I can't see anything wrong in my logs expect getting the 403 forbidden when calling api.telldus.com with your token. So somehow it is not valid even though it was sent from telldus in the first place.

Must be something with the trust between Telldus and Tellmon. I've deleted your account (but kept there data). The account should be created again on the next logon.

1. Has it worked before?
2. Have you tried to logon to "live.telldus.com"? Can you see your devices there?
3. Also make sure to confirm that you want to allow Tellmon to access your sensors and devices when you logon on Tellmon.net the first time.

Best regards

What kind of sensor have you set it to? You can set sensor type under Settings / Sensor. 
Also what have you entered as "Watt hours per blink"?
