Hi folks, Getting cold again, so the wife again starts asking to have some smart radiator control. She has been asking me this already for several years in a row, so should make some time for it. Have been asking already in the past questions about this in the community, but I hope that technolog…

Hello Bart :wave: Keep in mind that battery operated devices both in Zigbee or Z-wave meshes are not repeaters within the mesh. So your plan will only work if you either already have a zigbee mesh up and running or of you plan to add mains powered devices like plugs and lightbulbs at the same time. …

[image] BartButenaers: But can you explain why there is a danger issue?? If you mess up, you could, for example, ask the boiler to continually apply heat - while the boiler should (and will) have built in safety, do you want to rely on that? The risk might be low - I'm not an expert so I coul…

[image] TotallyInformation: Just make sure that when the system fails (as it inevitably will at some point right?) it does so with the TA connection open not closed so that the boiler turns off. Good one!!

[image] TotallyInformation: you are supposed to have 1 radiator without a TRV so that there is always some outlet for heat if things go a bit awry and the roomstat is supposed to be near that rad. Has been noted!!!!

[image] TotallyInformation: you are supposed to have 1 radiator without a TRV I think that depends on the boiler. Mine does not need that. [Edit] I might have to retract that statement. If by TRV you mean the dumb ones that just close the valve without any way of knowing whether they are o…

Welcome to my personal hell Bart. I have dreamed of a smart heating system for years and I have made it most of the way there, with some problems along the way. My problem is I live in a reasonably large very old house so I do not want to be heating all of it all the time (my heating bill was huge…

This all sounds very like my own motivation for getting into Node-RED and home automation (although I did mess about with X10 lights as a burglar deterrent many moons ago). It was literally "a dark and stormy night" a few years ago when I had to get up at about 4 in the morning to get a taxi to th…

[image] SimonB27P: a reasonably large very old house That is the same for me. [image] SimonB27P: I especially don't want to be heating bedrooms that are not being used or indeed, when I am working from home in my study, I don't want to be heating most of the rest of the house. Same he…

[image] SimonB27P: a timeline widget Hi Simon, thank you for sharing your ideas. It seems like we both need a similar solution ... Have you ever seen a (commercial or open-source) app that has an easy to use widget to setup/maintain a heating profile. If so, please share it so somebody mi…

[image] BartButenaers: That makes sense, although then you can only buy their TRV's in the future when you want to extend your system. I assume you don't have an extensive list of systems that fullfill your requirements ... That is mostly true. Though of course, you could still further extend…

It would have taken me years probably to get to where I was in minutes with the Wiser system given the amount of available time I would have to spend on it. Very true Julian. I actually went ahead and bought a starter kit for the Wiser system. I do like it and I was at the time concerned that I…
