@dkhayes117, good to hear. If your feeling generous please share the code (either on another thread or on the Exchange (could have a chance at winning the [Exchange Challenge](https://inductiveautomation.com/blog/icc-2021-evolving-the-virtual-experience)))

I will post it when completed. What would be really cool for the winner of the exchange competition would be a special badge on the forum that would show beside your username 😀.

did you ever get this working with the Ecobee? I'm working on a similar project.

Yes it works, but it has been a while since I've gotten to work on it. I'll post some code when I have time if you'd like.

Also, welcome to the community!

This is a ways off from being completed. My functions can be polished more, I basically wrote each one to work individually and was going to go back and combine some functionality, which I haven't done yet. When it is more polished, I will probably post the whole project on Ignition Exchange.

I have my api tokens and authorization stuff held in tags, which is not very secure. When I'm done with the functionality, I plan on storing those with encryption. Note it has been a while since these have been fully tested. Also note that you have to setup an ecobee dev account before you can use the APIs, [ecobee API](https://www.ecobee.com/home/developer/api/introduction/index.shtml)

```python

I know this is an old thread but I've encountered some difficulties with this.

1. It is implied that the auth code remains the same. I have not found that to be the case and I find that I have to request access or I get IOError: Server returned HTTP response code: 400 for URL: [https://www.googleapis.com/oauth2/v4/token](https://www.googleapis.com/oauth2/v4/token) unless I go through the access request process again. Even when I am trying to refresh the token.

2. I kept getting an error in the getToken script as the response could not be parsed until I stripped all of the newline,tabs and whitespaces.  
I will continue to poke around at this but am curious if I am doing something wrong.  
I modified the getToken and refreshToken Script to use the system.net.getClient() and that works really good..

I did get this to work. The only problem is the refresh token expires every 7 days so I'm working on that now.

Interesting. I wonder if that refresh token expiration timeframe is a recent change? Admittedly, I haven't touched this code in probably a year and a half and I haven't been checking if it works either. I find that Home Assistant works well enough for the majority of my home automation needs that I haven't bothered doing much with Ignition other than using it to log aquarium water parameters into a database whenever I test my tank's water.

I've read it happening to other people. There is a way to publish the project that eliminates it, but I'm not worried about that now. I've actually have setup up data flow and am pretty happy right now. I also am going to attempt to pull live feeds on our camera's.

I totally get your struggle with Google’s OAuth2 process—it’s no joke! I ran into the same roadblocks while trying to connect my devices through Google Home, and honestly, it felt like they assumed everyone had a commercial-level setup.
