eqiva 142461A0 UK Bluetooth Smart Radiator Thermostat

We've a unique setup in our bungalow where the attic space has been converted into an office. That's all there is on the upper floor of the home. So, being able to turn the central heating radiator off outside of Mon-Fri, 9-5 schedule saves energy. I looked into Tado, Nest etc. but they all seemed very expensive for what they offer (e.g. £500+ to kit out our home). A single digital TRV like this one therefore makes a lot of sense for us. But it's hard to see a situation where it could be useful for most people, especially considering the whirring noise it makes (see more below). Note that this TRV doesn't require an internet hub or indeed anything else in addition. It doesn't use wifi. It's just Bluetooth, and I believe it's the old style of Bluetooth that every phone has had for years. You don't even need a phone if you're happy getting on your knees and trying to program it using the buttons. Rather worryingly, the goods I received had clearly been opened. The box seal was fully broken. I'm unsure if it was a return. I found no evidence of it having been used, however. But perhaps you might want to bear this in mind if buying from this retailer ("Megga Distribution" [sic]). Installation was easy, because I read the other reviews here. Do that if you're going to buy this. I've included my installation steps below. They highlight some of the caveats others have mentioned. It seems to work very well. The motor is audible when it's adjusting the temperature – a quiet, gentle whirring for a few seconds. But this is true of all the digital TRVs. It whirrs on to get the radiator warm, and then whirrs off again to when the temperature is reached. This can happen several times an hour, of course, and so is something you know bear in mind if you want to use this in a bedroom, for example. Normal TRVs are silent. This one could disturb sleep if the heating is on overnight. The single-sheet printed instructions and the app are not entirely user-friendly. The app is typical of those for Chinese manufactured goods, in that the English isn't quite right (e.g. rather than tap Cancel, you tap Reject). Because of this, I wouldn't advise this product for people who aren't technically minded. But for those who've done a little DIY and aren't afraid of their phone, you'll probably be OK. For the rest, well, that's why Tado came along and made it all easy – but you will end-up paying a premium! However, this seems to be the cheapest option if you want a digital TRV controlled by your phone, and that lets you schedule daily heating for a room/radiator. And it seems to work. Here's how I installed mine. 1. Installed it on the radiator (turn existing valve to highest setting, unscrew its cap, remove it, screw on this one). 2. Installed the batteries (don't use the ones provided. Another reviewer said they leak. I used Duracells.) 3. Set the time and date using the controls on the thermostat. Don't do anything else at this point—another reviewer warns that doing anything else could block the Bluetooth connection! 4. Download the Calor BT app to your phone using the App Store, open it, and select to "Teach-in Device". 5. Press and hold the large circular dial on the thermostat until it says bLE on the display. 6. The app should connect, and you'll have to type in the code shown on the TRV. 7. Do everything from this point onwards on the app. Don't touch the thermostat again. 8. Don't upgrade the firmware even if prompted to do so! Again another review said this caused connection problems. In all likelihood, you'll never even touch the app again once you've set the timings you want—outside of times perhaps when you want to tap to boost the heat, which I would do perhaps if working in my office on a Saturday, for example.

GOOD: These are a useful way to exert more control over your home heating without paying more than double for WiFi-enabled TRVs, plus a hub, from Tado or Honeywell. I like: * Temperature precision (celsius versus cryptic 1 to 5 on traditional TRVs) * Scheduling * Mixed-room configuration * Bluetooth control from phone USAGE: In my use case, I work from home and sometimes want the office radiator on but don't wish to run around the house all day, turning old TRVs. The family needs heat in certain rooms at certain times of the day, but not others. I feel I having been wasting heat but lazily leaving some radiators on just to keep the home office radiator on. I didn't feel this was a problem that an internet-connector boiler controller could rectify. Whilst that would give me smartphone control from anywhere, and programmable timer control, it would still leave each room radiator requiring a manual turn. My central heating system has a boiler with controls but no wall thermostat in the house - limited control, then. My system has not been efficiently used. For now, that's how I am leaving it, leaving the boiler serving multiple of these units. Look, these are not going to take you in to the world of Nest, Hive, Evohome etc. You won't be setting your room temperature from the beach or on your way home from work from your phone - although that would be possible with internet control installed on the boiler; though I've no idea whether the boiler or controller or these TRVs would take precedence for the set-point temperature. But, for my purpose - which is to say, spending a lot of time at home, wherein the prime use case is merely programmability and a mixed-setting room configuration to avoid heating unoccupied rooms - they, in fact, offer *more* functionality than some of those other, "smarter" names. These have given me what I think is a smarter system. And for a fraction of the cost. Pricing up an Evohome setup on the Honeywell website requires their Wi-Fi base pack power supply and 6 x TRVs at a cost of £642. Compare that with £132 for 6 x of these units. Having learned a bit more about how heating systems work, I have turned up my boiler's radiator water temperature, giving the radiators a fighting chance at producing the temperature I state in the TRV set points. I suppose the optimum is to leave the boiler running all day and use the TRVs as the controllers. At present, I am using the boiler on timer, coming on just before the first TRV is due to call and turning off just after the last TRV is finished asking. That is not least because I'm not yet sure if I could fit one of these on my heated towel rail - meaning that rail would be running all day. Every so often, you hear a faint motor noise as the TRVs open or close the pin on your radiator head, allowing or stopping water from coming through. I actually find this reassuring - I enjoy knowing and understanding what it the TRV is doing for the rad and on my behalf; it's not something I had considered before. Whilst overall setup, per the manual, is a little confusing at first, I had no problems with Bluetooth setup, as some reviewers experienced. It was simply a matter of holding down the wheel so that the TRV can give you a pairing code to supply to the app. BAD: I don't like: * Bluetooth functionality is rudimentary and the app is not polished, though very welcome. * Paper instructions are not straightforward to follow, translated from German and quite messy. * LCD is not lit, so seeing the readout requires light. * The design won't win awards. The question is, will these things transpire to be as nasty as they are cheap? I bought one to test, then bought four more. Unfortunately, one of those shipped to me with a corroded battery, which had spoiled the battery connector, rendering the unit non-functional. All were fulfilled from Amazon, which sent a replacement unit. Another reviewer here has stated their unit/s spoiled due to battery corrosion after six months of use, pointing to quality of batteries used. I will be disappointed if this transpires in my case. Battery replacement wipes certain settings. I will write back if this fate befalls me. I haven't fully used the Open Window function or Eco and Comfort temperatures, and am trying to wrap my head around the Boost function. I assume Open Window works by detecting a sudden fall in temperature. UPDATE: Two months in, these are all definitely getting louder.

As a standalone programmable valve these work really well with multiple temp/time settings for each day. Bluetooth using the calorBT app works OK although the app isn't very intuitive. The bluetooth range is not great but bear in mind it's attached to a large metal radiator so is going to struggle with radio signals. You will not be able to control all radiators in one house from a single location. The motor can seem noisy during the night when the room is very quiet but it's not unbearable and doesn't wake me up. These are cheap so don't expect metal parts - they wouldn't handle being driven into with wheelchairs/buggies or kicked by stroppy teenagers. If you're into tinkering these make a great starting point to a smart-home heating system. I have 8 of these talking to two ESP32 devices with an openhab2 control system running on a raspberry pi. The bluetooth protocol has been reverse engineered so a number of open-source projects exist to control these valves from a central hub. It is not possible to read the current room temperature from the valve but you can see if it is currently open so it's simple-enough to figure out if call-for-heat is required to the boiler. I have had these valves for over a year now and they are constantly being polled by bluetooth and open/close periodically during the day. I've been pleasantly surprised by the battery life - I've only replaced the batteries in one valve and that is because one leaked. I suspect the close proximity to a hot radiator could have caused the leakage.

All'arrivo ero un po' contrariata perché erano rimaste le pile dentro e erano un po' ossidate. Ho comunque ripulito il tutto, montato e direi che non ho riscontrato altri problemi. Ho risparmiato e l'oggetto è davvero utile e funziona a dovere
