The history graph as mentioned by @RolandLT is simplest. I’ve been experimenting with mini-graph card, as detailed in this post but I don’t think the demand looks as good. Someone else posted a nicer graph but haven’t shared their yaml yet

@Stormhand , The Wiser TRVs only work with the Wiser Hub, they create their own zigbee mesh on its own channel. If you want to extend the range then the only way to do this is to buy a wiser smart plug. I have one simply for this purpose. Also according to DW it should also work like any other zigbee mesh in that you can daisy chain them. Alas the hub reports all smartplugs are directly linked to the hub (which isnt true)… We think its a minor bug on the wiser side but cosmetic and low priority…

@RolandLT , alas no you cant open the TRV with asking for heat from the hub. I have some radiators in the hall way which i only want on when we’re home. What ive done there is put normal trvs so when “any” iTRV asks for heat this rad is also heated… If you need better control then buy one of the many vanilla zigbee trvs, pair it to HA using smartthings/Z2M etc and control it using HA

yeah you need the hub, you cant control the TRVs directly.
I say this post too and it surprised me. Is there a complete description of how the TRVs open and close. I continue to have radiators getting hot when I would not expect it. The only time I have noticed the values opening and closing seems to be at the beginning and end of a scheduled heating cycle. It certainly is not every time heat is demand by the TRV is shown on the history graph for the room. I have seen the actual temp in a room rise and fall gently over time. At the bottom of most dips the heat demand signal shows, but not all. Sometimes the temp seems to rise by its self. There is no external heat source.
@Geoffw I’m guessing your post is in reply to mine.
I cannot help but think they don’t work the way suggested in that post. I hear the TRVs sound like they’re moving by small increments as often as I do them apparently opening fully or closing fully. Add to that the times they indicate heating but the rads are not belting out heat (as they can when valves are fully open).
Whilst I understand Wiser have some intellectual property to protect, it would be nice to have more technical references for this system.
You are correct I was replying to your post. Sorry I had problems as I hit the 3 post limit for a newbee.
More info would be very helpful when trying to troubleshoot. Right now I can only react to the extreme situations were the room is way over temp and the radiator blasting heat.
There’s an EU socket as wellv CCTFR6500

Thanks Angelo, well actually i will need the heat hub if i want to use your integration , beside use a generic zigbee coordinator in my HASS which i have the possibility but i get i will loose much of the outstanding goodies packed in the extension you have worked at long time.
That’s why i guess i will go for the hub, even if i’m not a big fan of…
Yes marco, you cant use the trvs without it anyway. Personally I love the fact that the integration works along side the hub. If my HA system dies (does sometimes), then the heating works, the Wiser App is more friendly than the HA UI for my wife etc etc etc
Thank you! I also found that there is another model CCTFR6501 which is without the pin. Are they all working with HubR?
Many Thanks Angelo, i spent a full day understanding product number across different EU countries.
I found some valves EER53000 which are SE that i will couple with the heat hub and make the full integration . finger crossed! I’ll keep you posted.
@Angelo_Santagata I’ve just noticed Schneider Electric WV704R0A0902 control via MQTT | Zigbee2MQTT
Can’t I disconnect TRV from the hub and use it directly via MQTT dongle which I have?
You can do this but if you research you will see a lot of comments that it looses target setting and keeps going back to 20C. You can give it a go but then you need to do all the work the hub and Integrarion does yourself in automations.
I guess main question in my case is “How much worse is using Wiser TRV as stand alone in comparison to other zigbee TRV?” As I have Wiser ones for all the rooms already.
In my situation I already have to keep adjusting Wiser schedule as weather changes - currently I have living room set to 22C to reach actual temperature of 18C.
I’ve ordered Sonoff temperature sensors and will have to do loads of automation myself to resolve this shortcoming.
CCTFRxxxx are french part number, I use them withe the hub
CCTFR6500 is the plug EU
For the TRV I suggest CCTFR6100
prefer the part number CCTFR6100 or WV704R0A0902.
The EER53000 were built for a previous system I think that they are obsolete and not recognized by the Hub…
Strictly speaking this might be a bit off topic, but I think this community may be good folk to ask.
I just had an email through from Electricity North West telling me my “rota block letter”, which may be used to identify when scheduled power cuts would affect my home this winter (if it comes to that).
I’m going to be away over Christmas, and will be relying on Wiser to stop my pipes bursting, black mould growing everywhere and the goldfish freezing solid. Everything worked fine last year, but this year the electricity may get cut off while I’m away.
My HA and Wiser Hub seem to recover well from power cuts (I’ve been getting the house required so plenty of “tests”).
Is there anything else I should double check, or other things fellow automated central heating enthusiasts might suggest in preparation?
Stick your Home Assistant box, Router etc on a UPS? I use this for my essential equipment. Dependent on how long the power outage is, it may not last though. I haven’t stress tested it, but my Dad has the same model and similar equipment connected and had an all day power outage recently and it lasted about 8 hours.

I’m not sure if this is exact but I believe the TRV’s open at 0.5 degrees above set point to take passive heat from other valves / roomstats calling for heat and when they drop below setpoint will call for heat.
This is the only explanation I can see for radiators getting heat when the TRV/roomstat is above setpoint.
