Drayton Wiser Yükleme Genişleme
Bölüm 1’de geleneksel sürümlerimizi değiştirmek için 3 kanallı kontrolör ve oda termostatlarını kurduk. Bu, akıllı bir ev ısıtma sistemi için seçim kriterlerimizin bir kısmını tatmin etti, ancak yine de bireysel odaların imarları da dahil olmak üzere bazı sorunlarımız vardı. Bu, bilge radyatör vanalarının önemli bir rol oynadığı zamandır.

Wiser için temel bileşenlerin maliyeti diğer birçok ürüne kıyasla rekabetçidir, ancak radyatör vanalarının maliyeti en büyük farkı gördüğümüz yerdir. Aşağıdaki tablo, evimizdeki benzer sistemlerin uygulanmasına dayanan farklı akıllı ısıtma kontrol markalarının temel maliyet karşılaştırmasını göstermektedir. Bu, daha akıllı çözüm değerini, şu anda piyasa tekliflerinden 500 £ ila 700 £ daha düşük olduğu için keskin bir kontrast haline getirir.

Notlar: Fiyatlar yazma sırasında bulunur ve DIY kurulumu içindir. Bu doğrudan bir işlevsellik karşılaştırması değil, gösterge verici bir maliyet karşılaştırmasıdır. Bazı sistemler diğerlerinden daha fazla işlevsellik sunacaktır, yani vanaların bölge kontrolü, coğrafileştirme, homeKit desteği, radyatör vanalarında görüntüler vb. Kullanıcının kendi özel ihtiyaçlarını belirlemesi ve değeri belirlemesi gerekir. Kendi oda / radyatör kontrolü şu anda kullanılamadığından, yuva veya kovan maliyetlerini karşılaştırmadık.
Radyatör valf kurulumu
Kendimizi tam bir sunum yapmadan önce her biri deneme olarak 34,99 £ karşılığında ScrewFix’ten daha akıllı TRV’lerden 2’sini satın aldık.
Geniş sıcaklık varyasyonları, mutfak / aile odası ve salon yaşadığımız iki oda vardır. Yağ ateşli pişirme menzili bir süredir mutfakta açıldıktan sonra oda hızla ısınır. Geleneksel TRV’nin yavaş yanıtı nedeniyle, akşamın ilerleyen saatlerinde rahat bir sıcaklığa inmeden önce oda sık sık ısınır. Bu odadaki dikey radyatöre daha akıllı bir statü takıyorduk.

The lounge wall area has approximately 60% glass which faces south. On a sunny day it can be like a greenhouse if the blinds are not pulled, even on a bright day there is a degree of solar heating. Whilst the lounge has low-e double glazing and 300mm of loft insulation it still looses a lot of heat in the evening. We have found traditional TRVs just don’t cut it. The lounge has three radiators, we would be fitting the highest capacity radiator with a Wiser stat.
First impression of the stat is that it looks similar to a regular TRV. There are no buttons or displays on the valve so they differ from 90% of smart valves on the market. Actuation of the valve is achieved by a simple twisting action of the top of the valve, plus will increase the temperature and minus will decrease it. The system will either increase or decrease the temperature by 2 degrees for 1 hour.
Fitting the stats was straightforward. There’s no instruction leaflet included but there are some points printed on the inner flap of the box so don’t thrown the packaging away just yet. The process for adding a radiator thermostat is:
01. remove the existing TRV. This Is secured by the knurled locking ring. Pushing down on the TRV body takes some of the pressure off the locking ring. This will expose the valve pin and the threads to screw on the adapter, in our case a M30 thread. This is the most common type and an adapter is supplied in the box for it and the Danfoss type. contact tech support if these do not fit as more adapters may be available.
02. fit the appropriate adapter ring, in our case the M30 threaded adapter.
03. open the Wiser app and go to settings and then rooms and Devices. We were creating new rooms and adding new devices. obviously if you have already created a room then the following sequence will change.
04. tap on add devices and update the number of radiator thermostats you want to add and then hit Next. This was a familiar process after adding two room stats.
05. At this point we created the new room names and assigned them to the channel on the hub we wanted them to control. We added the kitchen and the Lounge. The channel assigning step may not be needed if you have a single channel controller. Tapping next in the app takes to to the next screen advising to fit the batteries to the TRV’s.
06. remove the battery cover on the thermostat body by pushing the tab on the base and pulling the cover away from the body.
07. Insert the two AA batteries. There are no obvious markings in the battery compartment for battery orientation but a closer look and you will see a plus and a minus symbol punched out of the battery tabs. Insert the batteries.
08. once the batteries are inserted you may hear the motor running, we think this is to ensure the actuator is fully retracted. then the three LED lights will flash. Red under the plus symbol, blue under the negative symbol and the centre will flash orange and green.
09. next rotate the top of the thermostat in the plus direction to initiate connection to the ZigBee network, the center LED will flash green. The LED will turn solid green once the device has connected to the network. We had to do this a couple of times with one of the devices, we don’t know why as there were no specific error messages.
10. The next step is to screw the valve onto the adapter. once screwed on the valve top should be twisted to the minus symbol for 5 seconds. This will initiate the calibration process where the actuator learns the travel distance of the valve pin. We did find the valve LED’s did not align to the front of the valve when tight so we loosened the locking ring, repositioned and tightened the locking ring. We found the entire valve body twisted if the valve is not secured tightly. We cannot help but think there could be a tendency for the valve head to loosen over time after repeated twisting. If it does, there is a temptation to put some thread locking fluid between the valve and the adapter ring to secure it.
11. That’s it, the radiator thermostat appears in the room on the app. similar to the room thermostats in rooms & devices you can see the battery strength and signal strength.
After adding the two thermostats we went about tailoring the schedules for the two rooms. Our experience in the 10 days since we installed them is the temperature between the rooms is much more consistent than with conventional TRV’s. When in action theTRV actuator does emit a mechanical buzzing sound as it drives the valve pin up and down. We found this noise differs slightly in tone and volume depending on which radiator it was fitted to. most of the time it’s operation went unnoticed but it could be different in a bedroom. I compared it to a Z-Wave smart TRV we had fitted and they were comparable in volume.
Alexa Setup
This was something we were looking forward to. We have had little experience of Alexa so this would help us understand a practical application. here is the basic process we followed:
Installed the Amazon Echo app on an iPhone
Searched for the Wiser heat in the skills section and enabled it
Linked to our Drayton Wiser account
Searched for devices and that’s pretty much it
Within minutes Alexa was talking to us, it was that simple. plain spoken commands were quickly followed by clear responses:
Alexa what temperature is it in the Lounge? – “It is 18 degrees in the Lounge”
Alexa increase the temperature in the Lounge to 20 degrees – “I have increased the temperature”
This is pretty cool functionality. how much we will use this feature is still to be seen but it worked straight out of the box. We will experiment with Alexa to determine if we can teach it new commands – “Alexa it’s cold in here” – “OK, I have turned up the heating in the lounge to 22 degrees”.
The growing wish List
When searching for the app on the iOS app store we discovered that Wiser is a brand name used by Schneider electric across a number of platforms from home automation, energy management and lighting control. hopefully we will see the expansion of the eco system here in the UK. If introduced with similar market leading pricing as the Drayton Wiser then many competitors will have a battle on their hands.
In part 1 we compiled a wish list of some features we would like to see and in part 2 Drayton kindly responded with lots of helpful info.
Now with some more experience we have a few more items to add. As we mentioned in our previous article these are not problems with the system but enhancements some customers may find useful plus we need to keep the development team busy!
When boosting a zone the boost button on the app turns green, would be good to have this turn into a countdown timer so you can see how much time is left on the boost.
Add support for wearables ie Apple Watch. A quick flick of the wrist will tell you the temperature and give you the option to see when the heating will next come on and the option to boost.
Change or amend the signal strength icon to show a percentage signal strength – more on this suggestion in the following section.
In the ‘Away Mode’ give the option to set an ‘I’m back’ date and time so you don’t have to remember to turn the heating on when you return from your trip – geofencing may solve this too.
Add a link in the setting menu page to some of these helpful resources. Whilst this is an intuitive product and setup is well guided through the app, there are some subtleties you only learn from reading the detailed guides.
Ability to see how long the heating has been running. A log file or better still a graphical view.
An option to cost the impact of going to ECO mode. get the system to compare eco mode boiler timings vs conventional timings. This would give the users an indication of the ‘savings’.
The ability to tweak the transmission power of devices, so if a thermostat is in a poor spot, you can opt to give it more power, of course understanding battery life will drop as a consequence.
The ability to arrange the rooms or zones in hierarchical tiers. At present it appears rooms appear on the home page in the order you add them. It would be useful to have the option of ordering these in a logical fashion. example organisation:
The house – all rooms all zones
The downstairs – living rooms
Mutfak
Lounge
Çalışmak
Yemek odası
The upstairs – bedrooms
Ana yatak odası
Kids bedroom
