Data issue flag note - issue with elec_kWh on heatpumpmonitor.org

bazcurtis · 2024-08-27T21:16:09.236Z

I published my heat pump data yesterday to heatpumpmonitor.org and I have a note in Data issue flag note, that says issue with elec_kWh. I don’t know what this means.

If it helps my dashboard is here.

I assume this is why the site is still in waiting for review. Any help would be greatly appreciated.

I had a look, at it appears that your feed for “heatpump_elec_kwh” is empty. You might want to check that one. ID is 508046.

@Timbones thanks for coming back to me. I had a feeling that was what it was talking about, but it seems to have data in the feed. It definitely has data on the Home Assistant side. I can see what you mean on the Emoncms side. I will remake the feed and see if that helps.

@Timbones I have remade it now. The ID is 508129. Hopefully that has fixed it. I have updated the application to use the new feed.

@Timbones I think it was still broken. I asked Speak To The Geek and he suggest it was the fact the Utility Meter reset to zero. I have now set up another feed as kwhacc. Hopefully that will fix it.

You need a feed that is continuously increasing. The one plotted here appears to reset at midnight every day. Looks like kwhacc will do the right thing here.

Alternative method is to add Power to kWh step to the power input, which will accumulate kWhs for you.

Both methods are documented here: Calculating Daily kWh — OpenEnergyMonitor 0.0.1 documentation

@Timbones Thanks Tim, I appreciate the help. I think it is now correct. I have setup both ways, but add kwhacc method to the app. It is still flagged as waiting for review on heatpumpmonitor.org. Do you know how long it will take to be approved?

Timbones · 2024-08-29T21:40:05.611Z

We’ll check it again in a couple days to see if the kWh feeds are incrementing correctly…

glyn.hudson · 2024-08-29T22:52:25.607Z

I’ve just had a look and the kWh Feed is updating correctly. Nice work.

I’ve approved the system: HeatpumpMonitor.org

I noticed you’ve entered ‘don’t know’ under the hydraulic separation field. Could you post some photos of the indoor HP installation, showing any tanks and vessels you have installed? We can then let you know if you have a buffer tank or a low loss header, which would give you hydraulic separation.

@glyn.hudson That is a relief, thanks very much of the help @Timbones. I will write this up on my blog in case it helps others, if anyone can find it .

Here are the tanks. There is one in the loft and one smaller one next to the water tank.

Is the hydraulic separation issue the reason is still comes under the meter issues section?

glyn.hudson · 2024-08-30T11:39:56.909Z

The tank in the roof is a buffer tank, but it’s been piped as a volumiser. This will just be adding water volume to your system rather than hydraulic separation. If you did have hydraulic separation you would have a secondary pump inside the house.

This diagram shows a volumiser, the primary pump in your system is located inside teh outdoor unit:

This diagram shows a 4-pipe buffer which will be providing hydraulic operation, note the secondary pump:

You really want to insulate the DHW pipework in the airing cupboard, especially the DHW outlet pipe coming out of the top of the tank, a lot of heat will be lost from this pipe.

Sorry, not sure what you mean by this?

bazcurtis · 2024-08-30T16:33:06.907Z

@glyn.hudson Thanks for the information. All the pipes in the airing cupboard are insulated except that down pipe at the front.

I have updated the form to none now.

The site still shows a metering error and have a yellow (!), but nothing appears when I hover over it.

Apologies, this has now been removed

Thank you.
