This is my dilemma. I’m looking to have a heat pump installed by Octopus and they are refusing to install a level 3 monitor kit at the same time so I would have to retrofit it later on.
I’m considering whether to go with ESPAltherma instead as the setup looks fairly straightforward. I assume labour for retrofit would be at least a few hundred pounds (on top of the ~£500 cost for the kit).
With your CT consumption meter, do you monitor both the HP and hot water cylinder consumption?
In terms of stats from the cylinder, is there a separate kit for monitoring it? I’m thinking the main interesting bits would be consumption and current DWH temperature.
