Please don't think thi is an advert for commercial software or anything, this is a completely free project designed to help people like myself, who just wanted a better way to to manage their heating!

OK - HavenWise - advantage uses the Samsung WiFi interface. Homely and Planet Devices both use the MIM-19 Modbus board. So could be an expensive option. I have noticed that Homely and Planet are aiming their products at installers. There seems to be a 'don't let the user fiddle with the system and give them as little information as possible' attitude amongst installers and HP manufacturers.

All i'm looking for is detailed information on what that dark grey box outside is actually doing. I don't want an installer to remotely monitor the system and fiddle with it. I'll fiddle with it.

Had a bright idea. Make the £7500 BUS grant dependant on installers monitoring the system for 12 months from installation... Poor system performance - let them fix it.

As for the Open Energy Monitoring stuff - again expensive. It doesn't tell you what the HP compressor is doing for example. As for Samsung - would be really nice if someone could explain what FSV 2091,2,3 actually do in plain English.

When the ice throwing machine aka heat pump was installed I had a quick play with SmartThings. Not too impressed. Anyway noticed that they updated the App in DEc 2024. Looks like they added Energy and EHS Cloud. The Energy bit gives the daily/hourly/weekly and monthly energy useage and cost. I suppose it saves having to look at the data on the HP console. The other bit is interesting - EHS Cloud 'Enables installers to optimise and manage your EHS units performance'. Spoke to Samsung support - it was pulled before launch due to a few bugs ...

Should be released in the next few months. The problem will be accessing it as a user. May cost money. Back to the Energy bit. Login - Zone Current 34.5 degrees C. Select Heat pump 35 degrees. Heating Space 33 degrees, now 32. I'm watching it as I type. Select Schedule. You can then 'Add time block' at a Specific Water outlet temperature. Does this mean that it overides any Water Law setting for the time block? At the moment HavenWise are controlling the HP so I can't play with it. Could set multiple time blocks with differing Water Outlet temperatures ...

I understand from the wi-fi kit manual that this plugs into a separate part of the main board, so I hope to be able to use Smartthings and the manufacturers cloud to connect up with Havenwise.  

 My Planet install was included with the overall pump price so I cannot comment on its price, sorry.

Installed a Shelly EM and updated to premium (3 months free). Still can't get a decent power graph. I'm trying to look at the real time power consumption during a frost/de-frost cycle. So I've started to look at the Samsung API - just to log it's power. I think I'll give up on that one - no fan of HA and his mate JSON.

Is there a 'Samsung HP monitoring app' that uses their API to log what it's doing? Should have installed the Open Energy stuff. Came across something interesting in the Smart Things App - your installer should be able to remotely monitor the system. Any one know of an installer that does/can?

Anyway - the system is running quite well according to the MIM/Console COP data - last week a high of 5.47 and low of 4.2. That includes the HW (Weekly energy generation divided by weekly energy consumption). Not sure I trust the 'energy generation' as there is no sign of an 'energy meter' in the grey box outside. That was running with a Nest thermostat. Switched back to HavenWise. Should be able to compare the two.

There are still things in the Indoor Zone Status information and the Master indoor Zone information that I still don't understand and also the FSVs. Anyone know what 2094 is for? It's not in the book ... I'll e-mail Support in the new year.

I have a 12 kW Samsung with a flow rate of 16 l/min and it seems to work ok at my design temperature.
