Reconnecting my emoncms database to heatpumpmonitor

At some point the link between my self hosted Emoncms database and heapumpmonitor failed

When i try and “Manually reload system data from Emoncms dashboard”, i get an error ;
{"success":false,"http_code":200,"message":"invalid app or permissions"}
How can i reconnect this as there is nowhere that i can add a new API key, if that’s changed at some point?
There is definitely history but it seems to have gone from the public view

Sorry, I’m afraid non emoncms.org URL are no longer supported on HPM. Unfortunately, it was getting too difficult to con-ordinate versions and the latency of was causing issues for data processing.

We could offer you a free account on emoncms.org if you were happy to sync your data? Drop me a PM if you’re interested.
