Hi All - Getting to that time of year again to turn the heating on in the UK so plotting my attack for the coming months. Reading above about macro zones for heating has got me thinking if this is going to be a better way to approach heating my house, a 70s 3 Bed Dormer bunglaow with Ideal Logic 35+ boiler.
Currently downstairs I have
Living Room 2 x iTRVs (1 per rad) and Room Stat as temp was always out on iTRVs
Kitchen with Room Stat and automation for plinth heater if kitchen calls for heat
Upstairs
3 x Bedrooms with iTRV in each
Nothing in bathrooms or hallway.
I found last year that I had a schedule setup for each room which worked OK but just did not feel efficient, sadly I have not stats to back this up as I had to reinstall my integration when messing about with Homekit.
I am just wondering what would be the best way to approach zoning, say downstairs and upstairs. Simple answer would be room stat upstairs and down but then I am at a loss with what to do with the iTRVs - perhaps place a few furhter from the room stats?
Can you tell me something about how the room thermostats work?
Are they tied to a specific valve-zone - or can you use multiple of them within the same valve-zone?
If a radiator calls for heat, does the thermostat that the radiator is in also have to be calling for heat for the boiler to fire up?
Will the boiler fire up if just the thermostat is calling for heat?
I currently have a Genius Hub system and I leave the thermostat turned up high in a cool room so that it wonāt prevent the boiler firing up if any of the radiators call for heat. The boiler never fires up just because of the thermostat.
You add iTRVs and Room Thermostats to Rooms in the Wiser app. Two iTRVs in the same room average themselves between them and call for heat etc at the same time i.e. they act in tandem. Place a Room Thermostat in any Room and it will override the iTRVs temparature readings and take it from that instead, but it will still operate the iTRVs as one item.
A Room Thermostat in a room without TRVs will call for heat when itās needed and anything without an iTRV will receive heat unless you have dumb TRVs on the radiators limiting output.
The boiler will fire when anything is calling for heat.
Iām using this integration for a few months but now that the cold is kicking in Iād like to make some automation.
Iām happy with the current schedules the Wiser app has, specially with what I think is the ECO mode, that turns heating on and off before reaching the target temp so it doesnāt over heat.
If I want to start the schedules based on my alarm or stop the schedules when I go to bed, what can I use? I can just see how to boost or set manual temp, but it feels the Wiser system itās already quite smart and itād be a pitty to lose that
When you say āI currently have a Genius Hub system and I leave the thermostat turned up high in a cool room so that it wonāt prevent the boiler firing up if any of the radiators call for heatā.
Is the thermostat you refer to, the original device before the Wiser system was introduced? That stat is usually in a room with a radiator with no TRV fitted.
This is how my system is, since it allows a return to the original none-smart system very easily.
As Roberwigley says, multiple DW room thermostats can be added with or without iTRVs to form zones. iTRVs not allocated to a room thermostat will operate independently (effectively its own zone) and can still call for heat.
I think there a few things to clarify in your question:
Does Home Assistant already know when your alarm goes off and when you go to bed? If so, then these can be used to trigger your automations.
Why do you think you will lose Drayton Wiser features if you were to implement these automations? What specifically would be compromised?
Iām not currently using the integration but assume there is a way of enabling and disabling a schedule or overriding a scheduled with a Zone off? This would provide a way to turn it off at night and then enable it again in the morning.
Alternatively you could just set manual override of 5C for 2 hours when you go to bed (which should see you to the end of the scheduled time), and similarly in the morning, if your alarm goes off before the schedule start you can set an override for 21C with a duration of schedule start - now (or just 2 hours again if that is easier).
I donāt have a Wiser system (yet) so yes, this is the original system - Genius Hub - a startup company which were pretty much first to market in the UK.
hello
it is note easy to follow with one subject for all about wiser ā¦
My question i can use wiser integration with a network under ZHA or Z2M is a difference in support ?

Hi, Iām not totally sure what you are asking but let me have a go at answering anyway.
Yes, you can connect the iTRVs to your Z2M or ZHA Zigbee network but it isnāt advisable to do so. They apparently have extensions to standard Zigbee and I have noticed slightly odd behaviour with the iTRV I have added to my Z2M.
If you want to use this integration you should not add them to your Zigbee network, This integration is for the standard Drayton Wiser setup which has its own Zigbee network.
As @JasonBSteele has advised, this integration is for use with the devices connected via the Wiser Hub in a standard setup, not connected through ZHA or Z2M. Save yourself the hassle of trying to get them working independently of the Wiser Hub and just use this integration. It really is excellent.
@JasonBSteele@robertwigley
Thankās for yours answers. effectively , I am a beginner and i more understand , i donāt need ZHA ou Z2M i can see and manage zigbee wiser through the integration
best
Iāve looked around for an answer to this, both here and on other forums, but have been unable to find one, so I figured this thread would be the best place to ask. (I have posted on the Schneider Wiser forum but since Iāve asked about not buying their products I expect it will be rejected).
Will a non-wiser Zigbee repeater work as a repeater for Wiser?
The Wiser Plugs are very expensive and I donāt actually need a smart plug, I just need a range extender, so will any other Zigbee device which can work as a repeater work as a repeater for Wiser? E.g. Iāve got my eye on secondhand Tradfri, Sengled and Smartthings Zigbee plugs as I can get three of them (I need three) for the price of one Wiser plug!
If an off-the-shelf repeater wonāt work then will a USB dongle like the Sonoff one work? (Obvs in combination with an RPi and HASS or other suitable software). Iāve actually not setup Home Assistant yet but this would be a good motivation to do so!
@LGO44
yes i use this integration and i manage all the wiser device ( thermal ā¦ boiler . ). and i have a second zigbee network for the non thermal devices wiser SE ( lights, volets . )
I get the zigbee card, but not the schedule card. Both are installed in
frontend\wiser-schedule-card.js and
frontend\wiser-zigbee-card.js
but under āResourcesā I see
/wiser/wiser-schedule-card.js?v=1.3.3 Stylesheet
/wiser/wiser-zigbee-card.js?v=2.1.2 JavaScript Module
I have just deleted and redownloaded the integration 3.4.8
My Home Assistant is
