New data pipeline: Daily data summaries are first processed in emoncms based on underlying electric, heat power feeds, system temperatures and hot water/space heating flag feeds.
Support for seperating out hot water and space heating figures where the hot water flag feed is available - not supported by all systems
Fix issue with heating only meters that do not subtract defrost energy from total heat supplied
Improved handling of data quality issues such as an electric meter or heat meter dropping offline causing either very high, or very low COPs.
Daily summaries are then aggregated on heatpumpmonitor.org into monthly totals, last 7 days, last 30 days, last 365 days and all time summaries (it will be possible to use the daily summary data directly in the graphing tools but this has not yet been implemented).
Automatic loading of installer logo’s based on website favicon. Provides an easier way to identify installers. Installer name can be omitted in mobile view where the screen width is limited.
A learn more link that includes links to relevant BetaTeach podcast episodes. Will extend this to include relevant youtube videos as well.
If you are self-hosting your heatpump data you will need to update the emoncms apps module to include the new daily data summary processor code before the system can appear again on the list. Login to local emoncms, navigate to Amin > Components and then Update the Apps module (v2.8.4).
What about someway of showing hot water / heating % split of heat created?
ie, mine is something like 22% hot water last 30 days. Which I can see is high compared to some of the heat pumps out there.
Thanks @Zarch yes that sounds good. We are going to add tabs to select different standard view’s as well so perhaps a tab that explores this aspect in more detail too? Including the COP’s for the different modes?
also updated the manual reload button available on the system view, this can be pressed to reload the full data history, which is needed when e.g adding a dhw flag as the historic data needs to be recalculated with the flag data present.
Riddle me this one. I can see the separate DHW/heating COP now on the dev heatpumpmon chart.
But when I visit Emoncms - app view dashboard (but don’t log in) I don’t see the DHW/Heating breakdown.
Yes I’m going to write a longer piece on this. Your right of course. The change above is to change from a mixture of using meter heating only energy registers to using the power registers which go negative for cooling. Integration to energy is then in post processing. This also benefits the splitting out to space and hot water but has it’s own downsides when e.g the data logging hardware/software has an outage, though depending on when data outages occur they can effect both calculations based on energy registers and power registers…
The next step is to switch to heating and cooling meters. I will write a longer piece on this and some wider thoughts on dealing with data quality issues soon.
@TrystanLea Do you think, for those willing, you could add a feed for tariff and calculate the cost of heat? I know I’m not the only one who is operating my heat pump flexibly (in my case using agile, but others are using special tariffs), that might then show that getting the best sCoP does not necessarily lead to the lowest operating cost. It might be that you also have to display average room temp alongside that .
kW and W/m2 heating load (extracted from data when external temp is within +/- 0.5 of -2C)
The above values vs. design/epc heat loss and design heat demand. (help to see how accurate heat-loss assements are, and if they tend to be high or low etc)
