@richp I have an LC-13 working with your DH. Top job.
My question to Aaron was if and when are ST going to fully support it.
I use multiple Secure stats and switches to control the 3 zones in the house. The LC-13 compliments this by allowing me to time control rads that aren’t always in use. Nowhere near as intelligent as Nest but a lot cheaper (you can get the Secure stat and received for 30-40 quid on eBay).
Top work on the Danfoss DH. Much needed addition to the ST compatibility list (hopefully ST will add it at some point).
