Meross Smart Radiator Thermostat Hub Required, WiFi Heating Control, LED Digital Display, Compatible with Apple HomeKit, Alexa, Google Home, SmartThings, M30 x 1.5 mm, 6 adapters Easy Installation

It's summer here in Australia at the moment, so yet to test it in the cold. However, the instructions were good, combined with the youtube video. All set up without any issues once I got my head around the Apple Homekit app (never used it before). Seems to work well - heating up an already warmish bathroom floor. Simple interface in the unit itself and also through the iPhone - looking forward to using it properly next winter.

I have 6 of these now so all my radiators are covered and one has the older version of this model which still works great too. I have purchased pretty much everything that Meross have developed as my original reason for adding so much smart tech to our home was because my wife is disabled and all this tech has made life a lot easier for her to control things that she can no longer reach easily. We use these in conjunction with our Hive heating system and the two work seamlessly together both working really well with our voice activated devices as well as with the superb accompanying apps. 1. Installation I would say that the thermostats require a little more patience to install than say the plugs and multisockets but if you take your time and follow the Meross app's instructions and seriously don't rush this bit and read through carefully, making sure you understand each part of the setup before continuing. You have to setup the Hub first and I must admit I rushed it a bit being overconfident and when I came to install the stat I clicked on the hub setup again by mistake, rather than the stat. You will see if you are new to this setup process. Once I had mastered one stat, I went through the rest with ease and I would point out that these require two AA batteries and when they run down you will get a message letting you know that the battery is running low on whichever stat it is. You can choose from a preinstalled list of rooms when naming them or choose your own, whichever suits you. I did change them to our liking to make sure it was easier for Alexa to understand which stat to turn on and off for example. You can turn them on and off in the app and adjust the temperature in each one. When you do this with the app or Alexa it can take up to 3 minutes to respond but usually it does mine in less time than that. Might be the speed of your network and mine isn't great to be honest. One other thing I would recommend is if you are installing more than one, I found it easier to use the same radiator that is nearest to your router and hub. Just make sure to place the stat on the named radiator as soon as it's done so as not to get them mixed up. You will also need to go through the setup process if you have to replace the batteries but I am so used to the setup process now it's really not an issue for me and I do it really quickly. The batteries do last quite a long time before they need replacing though and it's easier to go into the app and delete the stat before reinstalling. The stats come with a 2 year warranty and so far I have only had one problem with one of them, when the part that grips onto the valve cracked and it wouldn't stay on properly. I contacted Meross and they couldn't have been more helpful and sent another one out literally the next day. So to finish off I can honestly say that I love these products and they have made it so much easier to control the heating both for me and my wife and I have no qualms whatsoever in awarding a 5 star rating for the product and the service.

Used this to replace an Aube Th232 thermostat which is not wifi, ugly, and costs the same price (?!). We have Tado everywhere else and it is a real shame that Tado never got around to releasing an underfloor thermostat otherwise we would have probably stuck with that system. Instead, from now on and for any friends that ask me, I'm going to send them to Meross! Before switching the thermostat I had to check two things - the rated power: how many amps will my underfloor mat draw? Builder can't remember, can't rip up the floor to find out... gee what do I do?? Well don't stress - check the rating of the current thermostat (Aube TH232 is 15A) and compare to the rating of the new one (Meross is 16A). If new one can handle the same or higher, you should be fine - the underfloor sensor: this was an area of uncertainty for me but I found the answers I needed. For the TH232 I found the sensor specs here https://ensupport.getconnected.honeywellhome.com/s/article/What-is-the-resistance-of-the-floor-sensor-circuit-for-the-Aube-TH232-underfloor-heating-thermostat?language=en_US and specifically if you look at the PDF chart it has 10k resistance for a temperature of 25degC looking at the Meross on Amazon you see the spec is the same: "R25℃=10KΩ" (https://www.amazon.co.uk/Thermostats-meross-Thermostat-Compatible-SmartThings/dp/B09K3Z4BD6/ref=sr_1_5?crid=31O74MARMGB2E&keywords=meross+thermostat&qid=1644772797&sprefix=meross+thermostat%2Caps%2C360&sr=8-5) It arrived quickly. Installation was ridiculously easy - had the exact same terminals on the back as the TH232 so just swapped it out. Wifi connection went fine. App works ok I do see the negatives raised by other reviewers: - yes the daily schedule has 5 points even if you only need 2 and you have to set it for every day. Make a cup of tea and just click through it, it isn't that bad and you only have to do this once - no pre-warm. Ok keep that in mind and set your morning temperature to start an hour or two early. No problem Also something else missing, which I find really helpful with Tado, is the ability to see a plot of temperature over time. This would, for example, help me work out how many hours it needs for pre-warm. No big deal though. Just ordering another two now for the other bits of underfloor. Any maybe some plugs too ...

So it is sightly fiddly to install, in that you do need to follow the Instructions rather than try to wing it, like you can with other meross products. Once installed, control is really intuitive. The main use is the schedule when and how warm you want each room to be during a week. This is as simple as not having the living room heated in the morning, or having bedrooms at a lower temperature during the days and only warming up in the evening. It's a pretty granular way to control heating but were no longer heating larger rooms when we're not using them. I also find the room temperatures to be much more accurate, stable and pleasant than the mechanical thermostatic valves. Bought two and think a third would be enough for the way we use our home. All in all, I have found Meross products really easy to use and reliable

I bought this to replace a 'dumb' thermostat as I wanted to control it from my phone and because I found the old unit slightly incomprehensible to use. The installation was straightforward, albeit I should have paid a bit more attention and initially simply replicated the order of the terminals from the old unit. After a bit of family advice and moving a couple of wires, all was well. Thereafter it connected quickly and I was able to create a schedule and have now set it to auto. The unit itself is attractive and the default settings mostly good. I did have to change the settings to just floor temperature rather than room / floor as the switch is outside of the bathroom. A good product at a good price that works well (also prompt reply to a technical query from Meross)
