OVO energy no longer connecting via integration

[jakeherp]

The problem

I have been using the OVO energy integration for close to a year and up until a few days ago it was working fine. However, since the beginning of this week the integration cannot connect to OVO energy anymore. I have removed the integration and tried to set it up again, but I keep getting the Failed to connect error.

I cannot see any logs that would explain this issue further.

core-2024.4.3

Looks like the APIs may have changed

Looks like the APIs may have changed

Are the APIs documented anywhere or are they internal and had to be reverse engineered? I was looking for API docs but couldn't find anything.

[timmo001]

Completly reverse engineered. Looks like the authentication has been changed to use oauth tokens now.

I will update the ovoenergy package to suit

[timmo001]

Changes made to package. Will release shortly and update the integration

[Astro-Pete]

Is this V2.0.0 released in HA yet? I have the same issue and the OVO integration does not seem to be updated yet.

[timmo001]

This is in the beta and will be released tomorrow

This is in the beta and will be released tomorrow

Perfect. Thx for the update.

@timmo001 have you been able to get the entities to come through in HA after the auth change? I've not had any luck, keep getting this in HA:

It also keeps asking me to reauthenticate (three times so far since I updated HA last night). Wondering if they have restricted their APIs and expire sign ins much quicker than before.

EDIT:

After re-authenticating again it now appears to be working. Will keep an eye on it and report back, if it stops working again.

I had the same problem. re-authenticating fixed it. Now it is working. Thanks!
