Ok AVF I need some advice and help. I have done a bit of home automation with Mi-Home plugs and lights as well as with Alexa and Harmony.... all the fairly easy obvious stuff. However I am looking for some automation ideas for my heating system but, as I am asking for help, as you can imagine things are not straight-forward. I am looking to control my heating so (just for an example) I have the heating on in my utility room where I am drying close but nowhere else, but then at night I have the heating on in my livingroom only.... and with these options I would have a wireless thermostat that turned the boiler off when it reached a certain set temp... So far so good and all fairly standard. Where my issue is and is a big stumbling block getting approval from management is this. I have a Victorian house and we have invested in victorian styled radiators in our main rooms (livingroom, Dining room, Master bedroom, bathroom). We have also got some very nice TRVs on them, but these are manually controlled and have no wifi or intelligence in them really. The radiators we have are in a gun metal/anthracite grey colour and the valves are a black nickel colour and look cool. To replace these valves with the standard white modern looking wifi/smart TRVs that are widely available would look hideous and "management" would have none of it and to be fair I am not overly keen on them myself. I am just wondering if anyone knows of any brands out there that do either black or dark grey valves that look a bit more in keeping with the style of radiator? If not then if there are any other options for controlling the radiators on a radiator or room basis?
