Home heating automation

Trvs have a great look to them, and they're rechargeable by cable, no more AAAs.

As I suspected, I wonder if the receiver will look different from that image, or will they just reprogram V3 extension kits. All the other Tado X is new from the ground up. That photo may have been a bodge, the marketing dept. jumping the gun while development was incomplete. I'd be curious to see if the Tado X app can integrate other Matter devices visible to the Thread border router. Some nice cheap Matter relays like below could have all sorts of uses, perhaps as remote receiver S plan switches for sensor stats, or to control the individual mains powered zone valve heads on UFH installations under control from Tado X sensors. Here's one I spotted.

Looks like they used substantially the same hardware alright. Here's V3 one, UK. Makes sense. I wonder will the UK CH/HW one be devoid of the OpenTherm connections as happened on V3 from V2. There were some grumblings in the UK forums over that.

What's the consensus on having multiple zigbee controllers - I have HA with a Sonoff and then Ikea with their Tradfri… I can change the channel on the Sonoff but I haven't seen that option on the Ikea hub? I'm just wondering whether it's going to become an issue as more IOT platforms move to zigbee.

Plumbed zones are passé, and expensive to retrofit. I've put off digging up the hall floor for so long to split off the bedrooms that I'm never going to do it, the capped of branch will stay capped and the associated unused pump is a spare for the other 4 in the system. TRV's on a few unused rooms can provide sufficient control, even just a few degrees lower. Completely off they'll get mould, and heat will enter through open doors and thin partition walls anyway.

The new HUBr and (new?) App illustrated in that manual seems to have the one stop shop smart home features I was half joking about. There's an image showing the app, with lighting 'moods' across the top, like 'Party' mood. There's a thermostat setting somewhere in the middle of all the smarts.

I'd imagine it's the new HUBr model. It's all in that manual you posted the link for. Looks like a techy wet dream alright!

On the continent TRVs are the thing, and smart ones are the big seller. Builders here are still doing the upstairs downstairs zone valve S Plan, and the cylinder, but with mechanical Trvs within the zone. People love cylinders and immersions, like hoarding heat in case there's a power cut or something. Smart trvs enable a better balance and more control, but can be used to limit heat to lesser used areas within a zone, say an office, or the kitchen later in the evening. The only issue with blanket smart TRVs is the possibility of not enough demand when a single radiator calls the boiler, and the boiler temperature reachs the limit temperature, which is less efficient on a condenser boiler. A digitally conneced boiler would br better able to modulation firing if the load was low, but these boilers dont suit HW cylinder heating at the same time, but are ideal when the boiler provides direct HW.

That's ideal
