Drayton Wiser Home Assistant Integration

I think the name attribute on the hub is only a v2 capability and we just fix the name for the hub to be compatible with v1 hubs (what us poor forgotten UK customers have). You can just rename the entity in HA if you want.

HI
yes i will but I don’t know how reconize it !
for exemple i have a boiler interface CCTFR6001 and i don’t know who is in the list
and i don’t know who are the 3 others in the list
II ask me , if i delete then , the real apparus will be link automatically ,?
If I when to add a new device, the menu ask me to connect again to the wiser hub ?? I was thinking I will be able to add a new device in the wiser network , like it is possible in HA
best
EDIT : i have deleted the item and found in the menu configurer reload . after that i got the sames entries , but not the CCTFR6001 ? the new item ares températures for thermo valves !!!

I think translation is an issue (your english is 100 times better than my french so dont worry).

@LGO44 would you be able to help?

lgo44 is French and very good with the v2 hub.

@msp1974 of course I can help.

what us poor forgotten UK customers have You can try to convince Schneider Electric UK to put the new devices in the Wiser portfolio.

the names of the equipment appearing in the HA list are given by the Wiser integration from the data provided by the Wiser box.
The boiler interface is not yet integrated into the Wiser application (I do not yet have this type of product installed in my home)
Can you provide us with the complete diag file


@bga.lambert (in french)
les noms des Ă©quipements apparaissants dans la liste de HA sont donnĂ©s par l’intĂ©gration Wiser Ă  partir des donnĂ©es fournies par la Wiser box.
L’interface chaudiĂšre n’est pas encore intĂ©grĂ© dans l’application Wiser (je n’ai pas encore ce type de produit installĂ© chez moi)
Peux tu nous mettre à disposition le fichier diag complet


Hello everyone,
Is it possible to integrate Wiser door sensors and push buttons into Home Assistant? At the moment I can only see heating actuators, thermostats and micro modules.
Is it possible to integrate door sensors and push buttons?

Bonjour Ă  tous,
Est-ce possible d’intĂ©grer les capteurs de portes et les boutons poussoirs Wiser ? Je n’y arrive pas, ils ne sont pas dĂ©tectĂ©s. Merci par avance.
PS : je suis Français et peut parler Anglais.

With a hub V2 it will be possible soon for the windowdoorsensor, for the push button it’s normally OK now they are seen as ononfflights.
Can you share your diagram file?

Avec un hub V2 la prise en compte des capteurs de porte est en cours
 pour les boutons poussoirs ça fonctionne dĂ©jĂ  comme des Ă©clairages one-off.
Peux-tu partager le fichier diag?

Wouldn’t there be a way in HA to set a offset/compensation figure for each TRV, once you figure out the delta?

Thats an interesting concept.
So with a large open plan lounge/kitchen/diner that has 3 radiators, I could just put the main thermostat in there, set existing dump TRV’s to fully on, and it will control the heat ok in that room?

Thats always a maybe answer. Obviously with a single roomstat, it is only measuring and controlling the temp/rads in 1 spot. If your room is very large, it may not heat evenly and therefore some areas maybe colder or warmer than you want. With trvs (accepting the delta issue) it will control/measure each area individually. But from a technical perspective, yes.

As @msp1974 says, but also remember that if you set the dumb TRVs to fully on, the room will heat when other rooms are calling for heat, so it could end up way warmer than you want. You would be best setting the dumb TRVs to either 3 or 4, which is around 20 to 22C for most TRVs and restricting the temperature from getting too high when other rooms are heating.

Great suggestion :slight_smile:

The problem with using a room stat and the dumb TRVs set to a certain level is that the stat could call for heat, and the TRVs would(could) prevent the room ever reaching the stat setting, so your boiler would be blasting away for hours pointlessly.

Very good point! You would need to make sure the TRVs were set to a higher level than the Room Thermostat.

Better still have Wiser TRV’s on the three radiators controlled by a Wiser room thermostat.

Personally i have ended up removing nearly all my Wiser TRV’s and just control my heating with a Wiser room thermostat and 3 strategically placed Wiser TRV’s.

What was the reason to remove all the other Wiser TRV’s?

A number of reasons

  1. Inaccuracy of measuring room temperature.
  2. Inefficiently firing the gas boiler everytime a TRV called for heat.
  3. Related to above, constant boiler cycling.

I’ve done something similar.

I now have two iTRV’s in separate bedrooms, two in the lounge + a Room Stat, and one in the kitchen.
These rooms are fundamentaly separate areas of my house.

The bedrooms and kitchen have heating in early morning (for breakfast).
Kitchen again early evening. Bedrooms later evening.
The lounge has a rising profile during the day.

All the other room radiators have regular TRV’s fitted and are parasites.
They use the boiler supplied heat whenever an iTRV requests a topup.
Trial and error with the settings to achieve most/ best perceived comfort.

You can’t micro-climate a house.
If every room radiator had an iTRV, you could set separate room temperatures for them.
But you will have to keep all the room doors closed in order to maintain those temperatures.
I suppose it could depend on the family and the house, but that never happens in our house.

You will also have a lot of boiler cycling:-
Consider that each radiator is (say) 3kW.
Once the temperature has been achieved in a room, it only needs topping up occasionaly to maintain it.
So your 20kW boiler fires up, ‘randomly’, at the request of each iTRV to top up a few hundred watts of heat to maintain each room to temperature.
Not very efficient.

I could go on with my thoughts, ideas and experiences, but I won’t.

Most radiators will be less than 1kw, with a modulating boiler like mine that only modulates down to 7kw i would need at least 7 of the 13 radiators on otherwise the boiler cycles. Even now i have boiler cycling but not as badly as when i had Wiser TRV’s on all except 3 radiators. My boiler is hugely over spec’ed at 24kw.

I haven’t thought about my setup in that way.
However my viessmann 30kw boiler can modulate heating down to 2.9kw.

I have itrv’s on every radiator apart from hall rad+towel rail.

Downstairs has 3x rads (kitchen/living/dining) with iTRVs grouped.
Then 1x itrv in each other bedroom.

I’ve got the pump speed dialled down quite a bit and auto balancing valves.

I think I still get a bit more cycling than I’d like.

Based on your thoughts, I might put a standard Trv on th diningroom (leads to cold conservatory). Then if bedroom 1/2 or 3 calls for heat, it’ll also still feed hall (no TRV) and towel rail.

My experience is similar, my previous house was much more insulated and wiser worked really well, whereas this house is a little less so


What I’ve done is

  • Radiators in the hallways are of the old fashioned type
  • Radiators in the lounge/dining/kitchen room are both set to the same schedule (different rooms though)
  • Upstairs bedrooms have their own evening/night schedules

If the house is a little cold then we have presets which heat the entire downstairs to 20/21c

Effectively Ive have two major zones

Why, same as @johnBoy , using HA stats I noticed the boiler was cycling constantly overnight and randomly during the day
 not efficient
