Hi Ben. Thanks for posting. I've also been looking at options for monitoring my 5kW system. This seems like a nice solution. It looks we have a similar set-up, the same Mitsubishi controllers etc. I am curious - are you also monitoring the Ecodan's output and Coefficient of Performance (CoP)? And if so, what are you using to do this? I contacted Mitsubishi to ask them if there were any add-ons available for my system, but unfortunately there are not. Thanks in advance, Dan
