I used to work for a European home automation company. Thing is, their gear is most cost effective in new construction and was very popular in Germany, Austria, Czechia, and Poland, but convincing anyone to wire for low voltage devices in the UK or US was like asking for ketchup on pancakes. There are a lot of reasons to like their tech, but they don’t really do retrofit, so it hasn’tanaged to make a dent in the market.
