I'd agree with that. To a large extent the distance between your wifi router, thickness/type of walls, etc will determine how well the communication will work. Hence placing the hub in an enclosed location may cause iffy connections. The TRV's are already in difficult areas being low down &...

Mount the Wiser backplate at a suitable location near the boiler. (1) Run a 2-core cable from the N & L terminals on the boiler or from the fused spur that feeds the boiler to the N & L terminals on the Wiser backplate. This could also be a 3-core cable including earth but the Wiser does not...

The dial timer is in effect the programmer. Looking at similar threads, the approach seems to be setting the integral timer to permanently on and then use the external thermostat connection to switch the central heating on/off. If I have read correctly there should be a control box cover at...

Depending on how the room thermostat is wired it could be fairly simple. If you can get a picture of the wiring at the thermostat. The keypoint is does it have 2 or 3 cores into the roomstat. If it's 3 the Wiser Hub might just be able to go in the same place as the existing roomstat. However its...

How is central heating side controlled today. Do you have an integrated timer? Is the current room thermostat wired or wireless? In principle the switching side of the Wiser hub is wired to the external thermostat connection in the boiler with the Wiser power input coming from the same source...

If the radiator does not have a TRV today, it's a job for a heating engineer (or skilled DIYer). You may need to drain down the CH system. There are some Youtube videos on the process but it's not something I'd feel confident to do. A job for the summer or just leave as is with no TRV.

Yes, they are independent. In that case the boiler would remain running as at least one area has not yet reached its setpoint temperature. As each room cools they can independently fire up the boiler. We need to be careful what is meant by a room in this discussion. In the Wiser system a room...

Your question was "can the Smart TRV's override the thermostat and turn on the heating by themselves?". If the roomstat & smart TRV are in the same room then "no" is the correct answer. If they are in different rooms, the TRV is not overriding the thermostat as they control separate areas and...

That is true if the roomstat and smart TRV's are allocated to the same "room" in Wiser. If however the roomstat is in "room1" and smart TRV in "room2" they independently control the boiler. Perhaps my use of zone is not good. Unfortunately in the Wiser app it uses "room" when it really means an...

If the zone contains both a roomstat & smart TRV's they will not call for heat as it's at the desired temp. Unfortunately the Drayton terminology is confusing, sometimes they use room other times zone. For example the single channel Wiser with two smart TRV's is described as multi-zone...

No, I believe in a zone with a roomstat & smart TRV's it's the roomstat that wins. Any temp seen within the Wiser app is from the roomstat. In essence the roomstat senses the temp and the Wiser Hub instructs the smart TRV's to open/close. If the zone contains 2 or more smart TRV's (and no...

You should not fit a smart TRV in the bathroom/en-suite as the electrics can be affected by the damp atmosphere. A regular dumb TRV is OK for either. That said, I don't have any TRV on the bathroom/en-suite radiators as these are my bypass devices. If your aim is accuracy of temperature, the...

If a radiator has a dumb TRV the only "control" is when it senses its local temp is meet and then closes. That will not trigger the boiler to stop of course. If the radiator has no TRV it will just keep heating until the boiler is triggered off by the room stat and all smart TRV's have also meet...

Yes, a smart TRV would work in that situation. One area that Wiser has an advantage is that local control does not depend on internet access just a working home wifi. On the back that there are several Home Assistant projects to monitor/control the Wiser system such as...

I have doubts that a kitchen is ideal for a smart TRV, there are too many external influences over the temperature such as the oven or hobs. You probably want to be able to control the kids room independent of others and that's good for a smart TRV. Likewise the study would be a suitable...

I assume you have purchased the single channel Wiser and have one roomstat together with your 5 smart TRVs. As you no longer have a fixed location for the roomstat (i.e. it's connected to the Hub via wireless) I would recommend you fit a TRV (smart or otherwise) to all radiators bar the...

No sign of insights+ in Wiser settings. That said, I'm not eligible as my miserable energy supplier refuses to repair or upgrade my faulty smart meter.

Insights is loading for me but at a snail like pace. Took about 5 minutes to respond

i have updated my post. I suspect it's the brown from EP #4 (or Hive #4) that goes to the thermostat as per the earlier reply from johnmdc. But you should check carefully before making any changes. Hence the recommendation initially to "just turn the stat to max" as that's not touching any...

There are several items to look at On the EP2002 you have terminal L with link to 5, also in 5 is another brown core. terminal C with a grey & green/yellow connected together For the Hive connect both browns from EP L & 5 into Hive L having discarded link brown (L->5) connect EP N into Hive N...
