merossSmart Thermostat, for Electric Underfloor Heating, with Timer, Programmable and Multi-room Control, Hubless, Voice/Remote Control, Compatible with Apple HomeKit, Amazon Alexa, Google Assistant

The electrician fitted this yesterday to replace an olde wolrde clockwork style timer on the gas boiler, that hasn’t worked since I moved into the house, and a massive prehistoric thermostat that was a blot on the landscape in my hallway.In contrast this looks sleek and unobtrusive and my heating came on just before my alarm for the first time in over a year! Just need to paint over the area where the old one was.Took about 6 attempts to pair to my phone on the Meross app (finally worked when I used the QR code label stuck in the mini manual).Once connected it was easy to set different times/temperatures using the scheduling in the app.Very pleased with my purchase ⭐️⭐️⭐️⭐️⭐️

Super easy to install and setup, working as expected. Built in schedule is useful to save costs with off peak heating and not heat up on weekends (home office). You can also automate and control remotely via HomeKit. The app also shows costs and heating history. You can choose where to measure the temperature from: air or probe.

So far very impressed with this thermostat.It is relatively easy to install but do read the write-ups from others about connecting a jumper wire in some instances.It requires a deeper back box 35mm minimum to install.Once wired up and the app is donwloaded using the basic features of this thermostat is very straight forward.It has a nice backlit display which can be set to a low brightness level when not in use and brighter when you use the thermostat.It also has a child lock function so that the temperature or other functions can't be altered or accessed. You can switch the function off easily from within the app or via a series of buttons on the thermostat itself.The programming schedule on the app is intuitive. It allows individual days/groups of days or all 7 days to be programmed as you wish. The on/off times and temperature are altered by sliding your finger across the screen of your 'phone, ipad etc. The app works well on both Android and iPhone. The app seems to be designed only for 'phones so it is smaller on a tablet (iPad at least) but does still work as expected.The other plus for this thermostat is that it connects directly to your wifi system (2.4Ghz) and doesn't require any other hardware.I haven't used the alexa/homekit system yet but will at some point.The lack of informative instructions is a negative. the thermostat app has numerous menus and settings but there is no explanation of most of these so you're left to figure it out yourself!It would be nice if there was a "holiday" mode but setting the frost protection to a suitable temperture (max 15C) can double up for this.

I installed this smart thermostat over a year ago to replace an old Honeywell wired thermostat. It works really well, to be able to control the central heating whilst not at home in winter ie: save energy when not required but switch heating on when you’re about to set off home so the house is toasty when you arrive👍🏼I left my original time scheduling controller connected as it’s a separate unit without a thermostat component, located near the boiler.I leave the old scheduler switched on constant as this smart thermostat now controls everything.This was really easy to fit. I bought a separate surface pattress box with rounded corners to match the contour of the Meross smart thermostat. My previous old Honeywell thermostat was surface mounted. I didn’t chisel into the wall because there’s a light switch on the other side, so no space.Wiring this was easy. My power cables were as follows:Brown is live L (2), Blue is neutral N (1), Black is switched live NO (3). You need to bridge L and Com with the small cable included in smart thermostat pack. Earth can be attached to a back box sunk into wall or a pattress box if surface mounted, or if neither of those, insulate and isolate the earth cable as there’s no earth connection on this smart thermostat.I’m also really pleased that it wasn’t too expensive and the quality is good. Highly recommended ⭐️⭐️⭐️⭐️⭐️

Really pleased with this. Looks great, simple to use, upgraded from a 'non-smart' thermostat so the smart functionality is great. Especially Alexa connectivity!Had an initial issue connecting the thermostat to the app, but this was due to my router and it was easily resolved. I reached out to the support team via the app and Lydia responded speedily and the issue was resolved quickly.
