I’m new to this forum and slowly getting to grips with what Open Energy Monitoring offers. I currently have Home Assistant running on a home server and have plenty of integrations for my solar, batteries, various aircons, etc. I do like what I can achieve with open energy, and I am very keen to hav…

Thank you to all those who helped out. Heat pump has gone in, the Heat pump bundle has been installed. I have integrated it into Home assistant and integrated the Valliant app. Also, set up an automation for hot water when there is excess solar :grinning_face:

The Level 3 monitoring bundle is fully pre-provisioned, it doesn’t require any setup. It’s plug and play assuming the heat meter has been plumbed in, and the electric meter has been installed.

Perfect. Have managed to get my installer to agree to do the plumbing bits. Order has been placed!

Having read the forum re HPs (but not actually got one) a key issue seems to be removing air. This was recommended a while back. [image] Removing air from the system Heatpump I have just installed one of these: " DiSmart 28mm Swiveling Deaerator" It works utt…
