A lot of AA rechargeable batteries are 1.2 Volt & not really suitable. They will work for a short time when fully charged. You need to take care to get 1.5 Volt. I got some of the Hixon 1.5 V 3500 mah which are great.

That's a great little bulid.

On the danfoss you have HW on and HW off, CH on and CH off and so on... what did you do with the off wires as the Kit 3 backplate only has on wires for the 3 channels

I have 9 TRV's and so far have at least 3 that have failed (new batteries and still completely dead). Given they are £50 a go - not sure I would go with wiser again. I find the coverage and app also a bit sub standard

I have integrated my Wiser system with Home Assistant. Lots more data available now and more flexible.

I use Panasonic and they last for 8-10 months. I used to have issues 2 years ago with the ECO Mode. It was heating up to only a 1 degree below the threshold. Wiser advised to reset the system by disabling Eco Mode for 2 weeks (I disabled for 4 weeks) and it did the job, for another 2 wks system was learning the rooms temperature and then started working fine, I recommend you this trick if you have similar issues. For Hot Water I am using Sonoff TH16 with the termal probe inside the cylinder. In this setup it is managing actual temp in the cylinder keeping during the day between 30'C and 38'C and increasing from 5PM to 45'C - 50'C. Highly recommended setup, I saved over 20% a year on gas for Hot Water. I use 9x TRVs and 3x Room Thermostats all setup with Alexa ;) PS: If you run Windows Tablet, just install Alexa and you may have a full house manager from one place. This includes: Sonoff, Wiser, Ezviz cameras and more ;)

I also have the insights plus with the extra smart meter, it’s great, it picks up real-time cost of your electricity and gas from your smart meters and gives you graphs of costs and energy usage per hour.

You need to use the new lithium rechargeable batteries, they are a full 1.5v or use Duracell pro batteries (which I buy in bulk packs), I get at least a 14 months from these depending on which room they are in before they need replacing.

The voltage supplied by a rechargeable AA battery is not the same as a regular alkaline. It's much lower at about 1.2 to 1.25 v. Not everything that can run with 1.5v AAs can use the lower voltage rechargeables. It looks like the Wiser Rad Valves don't either, well not very well at least.

rechargables are not recommended... jesus dont be thick

Please can you send a picture of the wiring

I think I know why. You are using the standard AA batteries 1.2V. As far as I know you are suppose to use the rare 1.5V ones. You can buy rechargeable ones Amazon. I'm sure this is why you have low battery or they don't last very long.

Rechargeable batteries will die much quicker because they degrade due to heat. Giving less and less charge each cycle. A good set of alkaline Energise or Duracell should do the trick, not the extra cheap ones, those are normally fake.

Hi, ref your initial video / comment on the noise being a problem especially in a bedroom. Now you’ve had them a while is the noise still an issue ? Any info appreciated

Rechargeable batteries have a totally different discharge characteristics to once use batteries and aren't suitable for such applications that use relatively high load servo motors. Hence the problem with them only lasting abut a month. Stick with good quality branded batteries - had no problems so far.

I've had my Wiser system with 8 TRVs installed for just over a year and it's taken until now for all the original cheapy batteries to fail - I think I'd be irritated if I was only getting 6 or even 3 months! I just replaced them all with Duracell Plus (bulk off Amazon) so we'll see how long I get from these.

Based on this I won’t bother with rechargeable batteries…..have you tried Duracell as they seem superior to most if not all 🤔

Are you using many roomstats with the trvs or just relying on the trv thermostat? Just installed mine last month and expecting to lose some savings with batteries.

I installed a wiser system in November (I work for the company that manufactures it) I also had my smart meters upgraded free of charge to utilise the insights+ part of the app - but you do have to purchase a Home Display unit for £15 to connect the meters to the app. This gives much more info to help tune the system and monitor the usage of energy. The use of Google Home looks very interesting !

Hi Handy Mistry I don't know what you are going on about, I have just fitted Drayton TRVs in my house and have to say the noise when activating lasts less than a second and is barely audible, certainly not enough to wake some one up. Regards Dereck

Just said changed wiring couple times... seriously? What's the point of part 2 than?

Where is part 2???

Hi. Can you please describe what you did with the wires from the old thermostat? Thank you

Can you advise where how you connected wires from the old one to the new one? As you have extra remote wires on CH5 and CH6?

I am having trouble connecting to my wifi. It's on 2.4hz but still after several attempts I have no success. Getting quite frustrated now.

@HandyMistry hello do you have any feedback on the noise of the TRV valve? This is my only concern for my daughter bedroom. You are the only one on KZbin with a so detailed review and most of other just put their voice or music during valve activation so is impossible to have other test to be done.

Thtah thing you put next to the boiler is it nessesery to have it in order to have themostaths on radiators work .... what I mean is can you just instal themostats to open and close radiators ? without instaling the hub ?

How is this system operating for you? I was thinking about trying it in my house where I have two wired zone thermostat/heating controls, one upstairs and one downstairs.I am not looking to add individual radiator thermostats as I have more than 20 radiators in total. I purely require the ability to control the heating when I am away from the house. Any comments would be welcome.

You said, "you had to change wiring a couple of times", could you share the wiring diagram the one which worked for you? Thanks.

I’ve installed this system however, the setup is solid red?! I’m broadband/Wi-fi is fine.. what could be the issue??

Your videos don't load

Why does this shit video now load?

How about just don’t be lazy and have manual trv

I bought the system recently and can say: this is really good. ECO mode does miracles :) I was concidering Danfoss Link however the quality of pre-sale support from Drayton convinced me to go for Wiser. ECO mode requires few days to compute a temp and time needed to heat up the room. I was surprised one day when the system ran boiler for only 60 seconds for one room but then realized that this was enough to heat up the rad to hit the programmed temp in the room. Amaizing! ECO mode combines temp from outdoor and in-room to calculate the best way to hit a target temp in the room. You can also access a graph with the temps, very nice :) What is not working well for me is open window detection... It is probably because the room does not cool down fast enough for the sensor to pick this event.. I wish to have IFTTT feature to trigger open window mode so I can use other systems to run this. I have entire house automated with Sonoff.. Another minus is for hot water management.. It only triggers a hot water for a time, there is no way to check temp on the cylinder. I am going to put back my Sonoff th16 to manage my hot water as it works better... (I have setup system to run HW when the temp on a cylinder drops below 38'C and stops when hits 45'C (have shower pomp, can't go to far with temp :) )

is that SELOTAPE !!!

So after a year of use would you still recommend this product?

Why did you use sellotape when changing the faceplate?

How did you get on with the noise of the TRV, that sounds loud, not sure I want that in a bedroom?

Could you also talk through the wiring?

How does this system cope if your Internet is down? I currently have a Drayton MiGenie smart controller and it has cloud capability with smartphone control, inside or outside the home. However, the smartphone feature _requires_ the phone to have Internet access _and_ the miGenie hub to have Internet access. If my home broadband is down, the smartphone app won't work EVEN IF the wifi is up. Being on the same network isn't sufficient, the Internet _must be up_. Fortunately, the wall box fails back to functioning as a traditional central heating controller in that scenario, so the schedule still runs but importantly the settings can all be accessed from the wallbox (basic monochrome LCD screen and menu access). Can you interact with the Wiser system in the event that the internet is down, but the wifi remains up?

We've had the conrad system for about 5 years now and while it does a fantastic job of keeping our house at exactly the temperature I want, the motors in the TRVs still annoy me a bit. Every time a new product comes to market, I hope they will address the issue, but it looks like the Draytons don't. In fact going on this video, the noise sounds even more annoying.

How are you getting on with this system after a few months? Would you recommend it?

How were these in the end? I’ve got some Netatmo TRVs but the motor just doesn’t seem strong enough to close the rad plunger so they heat up whenever the boiler fires, even if they’re set to Off

Hi - I've got the same query as DAve Ridgeway. How noisy is this valve? What has been your expeience so far?

How are you getting on with the volume of the TRV's motor so far? I was wondering if the issue was the same on different radiators. I think the noise of smart TRV's is generally quite important. The quieter the better!

How are you finding the noise from them? And how regularly do they make a noise? I’m thinking about this system. But would like to hear some thoughts 1st!

Nice review thanks. How does the system handle the room stat being in the same room as a rad with a Wiser TRV? Can you have Wiser TRV's on every rad or does one have have to be a regular valve that is always open?

Bought one, picking up tomorrow - I think you need to read the Data Sheet - looks like the delay has nothing to do with "the cloud" or your will for it to work ;) "Wiser Heat HubR - Timing resolution 1 minute" I will play with mine once I have installed it, though for now this seems likely to be the issue. Adding a link to the Data Sheet www.draytoncontrols.co.uk/sites/default/files/4093_Wiser%20Datasheet%20Web.pdf

I was so close to ordering but you seem a bit disappointed by the system. How are you getting on with it? I've looked at a few alternatives but keep coming back to a Nest
