My heat report has stopped working, what should I do?

Change steps so that they are as follows:
1. Disable WiFi on your phone running the Wiser Heat app (this ensures your phone is connecting to your system via the cloud)
2. Open the Wiser Heat app
3. Go to settings
4. Tap "account"
5. Logout of the app
6. Log back in to the Wiser Heat app
7. Re-open your heating report

If you have only just setup your Wiser Heat system and there is no data in your heat report please refer to this article When will I see my first Heat Report?
