Hi folks, We’ve had our heat pump in for a month and I’m wanting to make sure that my schedules are correct. Current DHW setup is: Setpoint 45C, Schedule 1am - 3.30am but water isn’t getting up to temp and COP is low at 1.7 average over the week. My EmonHP is showing that initial heat delivery is g…

Ok, so I had Grant out this morning, a really positive experience and knowledgeable installer (with a R290 at home). He used a programmer (see photo) to update the firmware on the external unit. [PXL_20251021_080856828] The programmer doesn’t show the previous firmware, but seems like it may hav…

Thanks @glyn.hudson . does the controller show the heatpump firmware version?

I checked in with Grant and they say my heatpump has the latest firmware.. although re update on the app their response is a little less confident.. HI Michael, This button refers to the cloud software of the app – it has no relevance to your heat pump – please do not press it. Show quoted text

How do get HA to trigger the water reheat, Dave? I am using a combination of the REST sensors and the econet300 integration but they are read only sensors. I have written to Plum for more info on the endpoints but I don’t think they communicate with end customers!

I think DHW boost is ID 115: HDWStartOneLoading curl -u "admin:admin" "http://<ECONET_IP>/econet/newParam?newParamName=115&newParamValue=1" Here’s the full paramater list: econet-param.md · GitHub I’ve not tested it since I don’t use econet any more. I use Econext which makes integration with HA …

Here are all the rest command endpoints I use, change the IP address.I assume you know how to call a REST COMMAND in HA, supplying parameter if required. This lives in the configuration.yaml section. rest_command: set_dhw_temp: username: "admin" password: "admin" method: put url: …

Thank you all. The very large parameter reference did not work for some of my metrics but I have managed to reverse engineer many missing ones. I shall start a new topic in case anyone wants them. I also seem to have a situation where only one circuit is actually obeying the weather compensation eve…

[image] germarsh: I also seem to have a situation where only one circuit is actually obeying the weather compensation even though it is set on three. The heat pump can only output a single flow temperature, I’m assuming it will always default the highest of the three zones, then the other zon…

Thank you Glyn - I discovered the circuits had a “minimal” limit of 30c on them.

@glyn.hudson randomly noticed you set up cooling on yours today. How well did that work? I assumed with rads it’s not worth it but don’t know!

Well spotted! Yup, it’s pointless trying to cool with rads. But it’s cool the unit can support cooling [image] Grant HP290 Enable Cooling Support white_check_mark Heatpump Despite what the manufacturer says the Grant HP290 actually supports cooling ‘out-of-the…
