401 Client Error: Unauthorized for url

The integration is working (big thank you for making this!!!), however I see a lot of errors in the log:

CustomerGid removed.

Oh, unfortunate. It looks like they restricted that api call, I see it on my end too as of about 5:10pm EST. I'll look into it and see if I can't figure something out. Hopefully they didn't lock down the API.

The odd thing is that I see entities being updated. It appears to be somehow transient.

Example of updates:

First failure:

Actually, false alarm on my end. I saw that my sensors stopped updating and assumed that's what it was but I think it's just #13 creeping up again.

If it's transient then I would expect it maybe happens an integer number of hours apart. The authorization tokens are valid for an hour so if it were to expire between calls I could see that happening. Alternatively it could be a rate limit thing. It looks like you have at least 14 channels (Emporia Vue Gen 2?) and right now this is set up to make a request for each channel, not one big request once per minute which is what I'm going to swap over to when I take care of #2. That means there could be a lot of requests in a short time which would maybe hit a rate limit and return that error.

[magico13]

The AWS API Gateway docs only list a 401 response when the authorizer has a problem and given that they use AWS for everything else it seems likely they're using API Gateway as well. It could just be a transient issue on their side. If you keep seeing it in the logs let me know but hopefully it's just a fluke.

Thanks for looking into it. I have 16 circuits and approx. 11 more will be added on a 2nd unit. So will be spamming them a bit...

Will keep you in the loop if I see more of this. Looking forward to see your batch mode coming online...
