MBUS reader kit, Y/N?

I’ve finally got my AWHP up and running a couple of days ago (LG’s Therma V 9kW, R32).

I want to set up a monitoring system with your “ESP8266 WIFI Heatpump Monitor DIY KIT” (and with a little help from my friend, engineer :smile:).

As I am quite ignorant on the hardware side, question is: should I buy MBUS reader kit? is it dependent on what I have on the heatpump main board?


Sorry, but I don’t know the answer, and it appears nobody who does know noticed your question.
@TrystanLea, @glyn.hudson or @johncantor might be able to help you.

Hello @Raffaele_Morelli sorry to miss your question.

I would recommend reading through the Installation and Setup page here it details all the different sensor options for the heatpump monitor board, you only need the MBUS kit if you intend to read from a compatible MBUS based heat meter.

If do not want to measure heat output from the heatpump, or dont have a suitable heat meter installed that you could connect our board up to then another option is to just measure the electricity consumption of the heatpump and flow and return temperatures to get a good idea of how the heat pump is working. You can do this with an EmonTx with either an ESP8266 adapter or an EmonBase which is a pre-assembled option rather than the heat pump monitor which is a kit that you need to assemble yourself.

No need to worry.

As I just would like to see what’s going on & don’t want to measure heat output, probably I’ll be better off with the second approach (emontx or emonbase) instead off the kit.
