Honeywell Home THR99C3110 evohome Smart Wi-Fi Thermostat Kit with Wireless Boiler Control Relay Box - and Improve Efficiency, White

First question I bet you are asking is what is in the box?1 x BDR91A1000 Wireless Relay Box (used to turn your boiler off/on)1 x ATC928G3000 Evohome WiFi Controller With Desk Stand And Mains Power UK / EU Power Adaptor.I have radiators which have Honeywell thermostatic radiator valves and thus fitting HR92UK  evohome Wireless Radiator Zoning Kit  was very easy (I got 2x4 packs for £372.00).Installing the Android app and setting up an account was easy and I created the heating schedules on the app rather than the device.Before with my  Honeywell Lyric T6 Wired Smart Internet Enabled Thermostat - works with Alexa , the boiler went on/off based on the hallway temperature. I now have this area set lower and can control each room individually (except bathroom, as I thought the condensation would get to the controller plus it acts as a bypass).The Lyric is no longer in use with the BDR91 mounted in place of the Lyric boiler controller.I am looking forward to lower gas bills and I hope the system will pay for itself in two years or so (maybe quicker if the price of gas goes up again).I should say the package made absolutely no mention of Alexa support but I see there is an Alexa app to link the systems together but reading reviews you have to be very clever to name your rooms unique so Alexa can understand you.I am just going to stick with the app which gives you full control in or away from home (no option to geo-locate turn on/off your heating in the current app). evohome Wireless Radiator Zoning KitHoneywell Lyric T6 Wired Smart Internet Enabled Thermostat - works with Alexa

Bought this during Black Friday at a cracking price of £175.15, however it was out of stock and needed to wait until December (but it was in before Christmas).After looking on line I decided to try installing myself which didn't take that long, much more time was spent on research than the installation. For me, the £120 quoted by Amazon was not worth the 2 connections to the combi boiler or the 2 for power that needed to be made. I will state I'm not a qualified plumber or electrician so if you do decide to fit yourself that is your choice.Once fully installed and set up (which took a couple of hours) I then added to Alexa. It's very rarely I use the app when at home. App is mostly used for turning on the heating when heading home on the train.Once I was happy the system worked I invested in the HR92 TRV and this is where it really came into its own. As it is only heating a particular room and not the whole house, it heats up so much quicker. The rooms stay at a more even temp.I believe this is one of the more expensive smart heating system but it works so well.Hardware:Can't fault it.Software:App doesn't allow for full set up, this needs the base controller. (Once set up I haven't touched the base controller)A way of viewing how long your boiler was on each day and which rooms would be a great improvement.

This has been THE BEST buy!! We moved to a 3 bed detached C17 thatch a year ago and bought 500L of oil a month to heat it between November and March to approx 18 ° twice a day. With over a foot of new insulation in the loft the bills kept mounting up and the house felt constantly freezing unless we had the heating in 24/7.We bought this last month (as well as the Hr92 TRVs and a room sensor for the en-suite with towel rails) and wow!! What a difference!!We hired an electrician to fit the relay and set up the controller and fitted the Hr92s ourself (all rads had TRVs so with a combination of adaptors etc it was quite straight forward).We no longer have draughts, the house is heated everywhere we need it comfortably at all times, it feels like the insulation in the loft is now actually working and gone is the pooling condensation from the single glazed windows! We’re yet to see if this has a dramatic improvement on our oil buying but we both agree if we spend the same amount at least we are now actually warm and dry!!Thank you Honeywell! What a game changer this clever little system is!

The good points about this control panel are that looks good and has lots of features for controlling the central heating system. It's pretty straightforward to use and the instructions provided are easy to follow to get you started.I would have given this device an extra star but for a few things which I feel could be improved. Firstly, the touch screen - it's not very responsive and I find I often have to press on the screen several times before it reacts. Secondly - since this device connects to the Internet, there ought to be an option to export your settings (that would also open up the possibility of being able to save more than one profile for each connected device). Lastly, the idle screen - it's way too bright and there ought to be a way to make it less bright without having to reduce the brightness of the settings screens. An option to have a white clock on a black background (as is currently available in night time mode) would be a good feature and there should be an option to completely turn off the idle screen at night as even with the white clock on a black background, it still lights up my bedroom if I leave the door open for ventilation.

Still a work in progress really but so far I am more than impressed for a couple of reasons:1. The manual! No need to go tracking down stuff on the internet, though that doesn't hurt. The manual has the answers and you can take it with you to the room you are connecting.2. The simplicity to enable the device on the internet. Create an account, link the machine to the account and you are up and running. I then downloaded the app to my phone and it is easy to use.3. That simplicity goes to connecting devices too. I haven't connected the boiler yet but have started adding the TRV devices.Just one job to go and that is to see if the old Honeywell wireless relay box (circa 2013/14) connected to my underfloor heating is compatible with this and I will be 75% of the way to full connectivity.
