On HeatpumpMonitor, you can compare data from two or more systems.
You can also compare a system to itself, across different dates by unticking the “Match dates”.
This could be useful to assess the impact improvements that have been made.
For example, I’ve compared my system (#1) over the last 3 months (red) against the same period in the previous year (blue), having switched out the room thermostat I was using:
I’ve just wanted to do exactly this, compare my own system to itself over the last two weeks but I think the bug you mentioned you 2024 dates is making this not work.
It would be great if this could be fixed as it makes assessing the performance impact of any system settings changes straightforward.
EDIT: Ah yes, I see that in the response for the GET /timeseries/data request: {"success":false,"message":"API only supported by systems hosted on emoncms.org"}
I do feel like the tool could pull my system’s data at some point as I remember using it to compare my system to itself after changing settings
I think I am fully up-to-date (the heatpump app has the recently added option to track heatpump_error for Axioma heat meter error state), still no dice in the compare tool.
