Just to let you know, your question inspired me to relook at our events that we fire in the integration. v3.2.2 will now include events for room started heating, room stopped heating and room boosted. As such, you will not need to have the first automation that is monitoring for the boost, which should be more performant on your HA env. Expect this version to be out this week.
Example of your automation with v3.2.2
alias: Cap boost temperature
description: Listens for wiser_room_boosted event
trigger:
- platform: event
event_type: wiser_event
event_data:
type: boosted
variables:
cap_temp: 23.5
room: "{{trigger.event.data.entity_id}}"
target_temp: "{{state_attr(trigger.event.data.entity_id, 'temperature')}}"
condition:
- condition: template
value_template: |-
{% if target_temp|float > cap_temp %}
True
{% endif %}
action:
- service: climate.set_temperature
data:
temperature: "{{cap_temp}}"
target:
entity_id: "{{room}}"
mode: queued

Could we also have an option to hide devices?
I have some plugs which are just used as routers and so donāt need to have a schedule.
Give me more of an idea what you mean.

For example:
āFish Tankā is controlled by HA automations which are more complex than the native Wiser functionality could offer.
āSpare 1ā is just used as a router / repeater and doesnāt have anything plugged into it,
So to keep the interface tidy Iād prefer to hide both of these so that they donāt appear in the schedule assignment section.
Just being a bit obsessive on the look of the interface - certainly doesnāt detract from what must be one of the best supported integrations available for HA!
I wish Iād read the previous messages here about rechargeable batteries before taking the plunge and buying a load of them for my TRVs. They all have a voltage of 1.2v so after a short time the TRVs report low battery!
Oh well, theyāll have a use in remotes and clocks for years.
Just an FYI - not integration related - I was having issues with one iTRV constantly dropping its connection - after troubleshooting it was specific to the location of the valve, not the valve itself. I rotated the valve through 90 degrees and it has been solid since.

Hey guys! Thank you for the great job here, without your integration Iām literally blind.
Not the integration issue, but I havenāt found a better place to ask: for some reason my wiser heats the room above the set temperature for 0.1 - 0.3C, the demand calls are clearly visible on the chart. Has anyone experienced that?
Added: no any smart modes enabled
It made quite a difference for me on a weak iTRV signal too. Iām guessing it is down to the orientation and/or small position change of the antenna. Perhaps the body of the iTRV itself can obstruct the signal a little from certain directions.
Which way are you orienting the iTRVs to get a better signal? Mine are installed horizontally and I have the Wiser logo and +/- at the top. Not really experiencing dropouts (that I have noticed), but wondering if I should change orientation to make sure I donāt get any.
On my radiators (all drayton style valves) these Wiser TRVs can rotate over time even if the lockring is nipped up tight.
My iTRVs are all vertical. I had one develop a weak signal (20%). It had rotated from regular use. I rotated it back, and it went to 40%. I then tried it at various points of the compass and there was a variation in reception reported in HA. FWIW with that particular TRV, I found it better with the TRV display pointing to the hub. It may just relate to how surrounding rad pipework interferes with the signal and no set rule.

A generic, non-integration specific question!
What do people think is the most energy-saving way to use individual room control? We have an on/off boiler (no modulation), and so far have just been setting each room as we want it. But does this use the boiler most efficiently?
For example, if we heat just the living room at 7pm, then heat just the bedrooms at 11pm, the boiler will fire up at both times, usually a little at 7pm but at 11pm itās heating the bedrooms from stone cold so will be on quite a bit.
Is this the best way? Or would it make more sense to open the bedroom TRVs at 7pm when the boiler is already firing to heat the living room? Would splitting itās heat output across both rooms be a more efficient use of itās on time, or would it still end up using the same gas overall? Does it matter that as an old boiler itās grossly oversized for just heating a single room?
I think you could have a meltdown trying to figure out the most gas-saving way to run this system

I think this is a very complex question and i think the answer is it depends.
So what do I think it depends on?
-
Your boiler. Depending how old is old and whether it varies how much it is heating the water based on return flow temp. Even old boilers will do this but if it is victorian
it may only go on/off. -
Your plumbing and how insulated it is around the house.
-
Your rads and how good, bad or indifferent they are at giving off their heat. Links back to 1 and return temp.
-
Temps it is starting to heat from. Lots of different opinions as to how efficient it is to keep at regular temp versus let go cold and heat when needed.
-
Insulation of house and how much heat leaks.
I think this then means that for some it is more efficient as you are doing it and for others heating all at once.
Best way to find out is always to measure if you can measure your gas use or even how long boiler fires for in both scenarios. With varying outside temps it is often a complex process to do and probably the answer is not that much different.

This might be a question for @jamiebennett. I was also going to post something similar. My setup is a two channel wiser hub with several trvs (love the system overall). Iāve been doing some research around this and have decided to line my schedules up so that certain groups of rooms heat at various set times throughout the day in order to mostly avoid single rooms calling for heat apart from when this is desired (eg boost in a single room). However, sometimes some single rooms do still call for heat when it is not particularly desired, especially when I have set back temperatures set overnight. I feel as if that this can be the weakest aspect of smart thermostat systems with many zones. I suspect that some more could be done to the heating algorithm to try and avoid these situations. This could avoid one room calling for heat as it has just fallen below the setpoint whilst another room which is just above setpoint not calling for heating until it falls below the setpoint perhaps in as little as half an hourās time.
In addition to this, I think it would be very useful to have some documentation which explains that it is not always better to micromanage singular rooms without setback temperatures - this would be very valuable.

On the face of it arrranging schedules to minimise instances of single rooms calling for heat would seem the most energy efficient. If you can get away with, say, heating the bedroom earlier to coincide with the living room and the bedroom holds heat well, that seems a good idea.
However taking this approach to its conclusion, you regress to the central stat with manual TRV model. One set of on/off times for a set of rooms.
Whilst I try to do this, some rooms lose heat much faster than others. I have noticed the north facing bedroom is the worst heat loss culprit. The integration temperature graphs have been an eye opener in this respect. Sodās law, this is the room we wish to keep warm for the most hours per day! Our house is occupied almost 24/7 and there are elderly to think of. Gas consumption has been high in the past. I really hope I can get it down a bit by not heating rooms unnecessarily. I think that means heating rooms selectively. My thoughts were if the system is pushing heat through 1 or 2 rads rather than 3+, it must require less energy. My old boiler might not have variable output, but hopefully is not running as long. I think the pump speed plays a a part if you are heating a small subset of the rooms at any one time.
Gas consumption compared to this time last year looks favourable but I have not factored ambient temps. My old boiler was not functioning right for some time and the issue was exacerbated after fitting the Wiser control as the boiler was going on and off more often. I have fixed it now so hoping things will improve further.
It was because of the boiler issue that I did not switch to eco or comfort mode. It would be good to know what if any AI is applied when neither of these modes are on. I hope none, as I think my boiler prob would upset the secret algorithm. This is the first cloud type home application I have ever used. Always avoided it before. On buying the Wiser system, I initially planned to block the hubās access to the WAN but Iāve relented for the time being as I might try the energy saving mode soon.

Also important if youāre not heating rooms to keep doors closed so that heat from rest of house does not propagate into them and heat lost that way.

Mine are all installed vertically - all but the one that was giving me a problem have the +/- facing directly into the room - For the āproblemā one I turned it through 90 degrees so that it is now facing away from the radiator

Yes thereās just so many variables. Iāll probably have to fall back on the gas bill, but even that is tricky to correlate when the outside temp varies. Itās unfortunately tough to measure how much the boiler is firing, since even when the system is calling for heat if the return water temp to the boiler is high enough (from only going through one or two rads) it will shut itself off.
Pump speed is another factor, I could try slowing that down to see if it allows the water more time to dump heat and prevents this short cycling.
I have an old boiler that can short cycle. Wiser (or any other controller AFAIK) doesnāt know when this type of boiler is actually firing. Before I got the wiser, I tried measuring how often it was turning on and off using a raspberry pi zero with camera fixed to the peephole and looking for bright/dark frame average and recording the timestamps to file.
I then had a pump go bad and it was replaced with an grundfos alpha2 pump. This has some alternate settings such as continous pressure (the other smart modes donāt work well if you have an auto bypass valve as I do). I now have the pump on CP1 (lower continuous prrssure). This, in theory, varies the power to maintain constant pressure. This seems to reduce short cycling whilst upping pump power when demand increases. Now I have got the boiler thermastat fixed too, the system seems to be running better.
