Connection closing occasionally

[mvujica]

Thx for this great project, looking for something like this for my rpi automation for a long time. Occasionally I get connection problems from Google Assistant to NORA; been checking it regularly now and had 2 failures in 4 days (averages one in 48h), if I update nora-config node and deploy flow everything starts working normally again. Is there an issue on the backend and is there a way to create some sort of watchdog to reset the connection? I really hate the idea to reset node manually every few days; it beats the point of remote control. Thanks again. Marko.

Service restarts once a day so the connection should drop at a 24h average (it's how heroku works https://devcenter.heroku.com/articles/dynos#automatic-dyno-restarts).

The Node-red plugin retries connection automatically when connection breaks but might take some time depending on the load on nora.

Any relevant nora output logs from node-red?

Thanks for a really quick response... There is one error (nora: sync error (invalid object for sync)):

When I logged in node-red around 9:30 today all nora nodes were connected and displayed right status, is it google to server side problem?

I have the same problem. I have to change the token in the NORA config node for the new one generated in node-red-google-home.herokuapp.com.

Why the token changes every day? Is there a way to update the NORA config node automatically with the new token?

Alternatively, how can we mount a server like the one that you mounted in heroku?

[mvujica]

I can confirm that as of 18th of March I had no issues with NORA connection, service restarts once per day but reconnects successfully. Should we close this?

I'm still having problems. Every day the token changes and I have to update it in the NORA config node. In other hand, every time I access to the NORA's heroku website to get the new token it ask me to login again (using Google account). I don't know if that can be the problem.

Thanks!

Every day the token changes and I have to update it in the NORA config node.

Token changes every login. That doesn't mean you have to update it. It's because of how signing works.

In other hand, every time I access to the NORA's heroku website to get the new token it ask me to login again (using Google account).

Because the cookie expires after a few hours.

When I log in again, the device list is empty. I have to update the token in Node-RED to get the device list again. Also, the Google Home app and Assistant shows/tells me that the devices aren't available.

This means that on restart your devices are not synced. It works when you update the token because on restart they don't have invalid properties. They probably get set via some other messages. If you have thermostats, make sure the humidity is 0-100. Same for the brightness for lights.

Still getting occasional nora: sync error (invalid object for sync) and flow stops updating google servers. I guess it's client-side problem, could you add more logging on nora nodes? I did patch it by automatic flow restart every day but feels like a hack, I would like to get to bottom of this. Thanks again for nice work! M.
