City of Austin Opower authentication problem

Saw the City of Austin Utilities (Opower) integration in HA Core 2024.2.0, so tried to use my user/pass to connect.

Connection fails. Typical debug entry:

KeyError: ‘X-Ratelimit-Limit’

2024-02-08 16:37:16.459 DEBUG (MainThread) [homeassistant.components.opower.coordinator] Finished fetching Opower data in 3.329 seconds (success: False)

Does this indicate COA Utilities is “throttling” the connections?

Or is the failure to connect because of something else?

I can login directly to the COA Utilities website just fine.

Only other thing I can think of is the fact we have 2 meters - one for solar generation, and one for usage. Perhaps this is confusing the Opower integration?

Thats exactly what


So you’re sending more requests than they allow for some reason and getting blocked.

That not really correct her.

A KeyError you will get in python when you try to access a key in a dictionary that does not exist.

The response returned from the server does not match what the developer expected to get back.

I’m having the same issue and I don’t have solar. I was very happy to see COA Utilities now had an integration. Can’t wait for it to function properly! Although I’m not sure what difference it’ll really make.
