What can I do with the LightwaveRF thermostat?

The LightwaveRF smart thermostat allows you to set and monitor your home’s temperature, when used with the LigtwaveRF boiler switch (N79QJ). The thermostat communicates via RF (radio frequency) to remotely control the activity of the boiler switch, switching on the heating when the air temperature falls below the thermostat’s settings.

The smart thermostat features a number of premade and custom schedules or settings that allow you to control how and when your home’s temperature is adjusted. Basic settings can be used to control the running time of your thermostat, allowing you to pre-set 'off-periods' to fit around your lifestyle. Other features such as boost, allow you to quickly increase your home’s temperature for a set period of time. Day- to-day heating schedules can be used, as well as the thermostat’s away and holiday modes, to specify the number of days a particular schedule is active. The thermostat features a default frost mode, allowing a minimal temperature to be set, to avoid damage to pipes or electrical items.

When used with the LightwaveRF Link (A23RX) and LightwaveRF boiler switch (N79QJ), there are two main benefits that become available to your existing LightwaveRF thermostat. The LightwaveRF Link allows the thermostat to be controlled via an app, allowing more intuitive control and a number of features such as being able to save custom heating schedules. The second benefit is the ability to further link your LightwaveRF thermostat together with other products within the LightwaveRF range. This allows PIR (passive infrared) sensors and smart lighting to be linked together with your heating, allowing you to achieve smart home automation.

When used with the LightwaveRF Link (N55LL), LightwaveRF boiler switch (N79QJ) and LightwaveRF radiator valve (N81QJ), this upgrades and takes advantage of the LightwaveRF's great modular design. The radiator valves give you zone control, allowing you to only heat the rooms you need, when you need them. This effectively changes your home central heating to a smart heating multi-zonal system. Each TRV (thermostatic radiator valve) will control the flow of hot water to the radiator, with an inbuilt thermostat which will monitor and activate the valve, depending on your set temperature.

The LightwaveRF thermostat does not have any annual fee/subscription, it is a solution to home heating that adjusts both your heating costs and comforts.

How can I control the LightwaveRF thermostat?

The thermostat features a set of on-board controls, giving you access to your home’s central heating, whilst also monitoring the current settings or modes. If used with the LightwaveRF Link an intuitive app, available for free, allows you to access and control your system from multiple devices simultaneously. Compatible with any iOS 5.0 device or higher including iPhones, iPods and iPads and Android devices running 4.0 and higher. Control your smart heating over Wi-Fi as well as 3G/4G. You never have to worry about accidently leaving the heating on, saving on your heating bill and reducing your carbon footprint

The thermostat also supports LightwaveRF’s remote heating controller (JSJSLW928), allowing the thermostat to be controlled from either the on-board controls or a remote control.

Will the LightwaveRF thermostat work with my existing central heating system?

The LightwaveRF thermostat is compatible with different zonal systems and setups depending on which additional LightwaveRF products are installed. It can be used for heating only (requires LightwaveRF boiler switch), or different heating zones (requires LightwaveRF radiator valve)

This kit does not contain the RF boiler switch, these are sold separately and required for installation (N79QJ)

How do I install the device?

Installation of the smart thermostat is easy, due to the pre-assembled and pre-wired control unit, requiring just batteries and syncing with the boiler controller. The boiler controller (sold separately) must be fitted by a competent person, and installation must comply with the guidance provided in the current IEE Wiring Regulations and current Building Regulations.

Rated 3 out of 5 by from works with major teething problems I'm quite an early adopter, so I'm expecting some radical changes as the system develops. this is my review on 29.10.2014 Initial set up was hit and miss needing to not only sink the boler switch to the wifi link but also to the thermostat several times before success . worked with a delay for two days and currently requires going into the apps room stat temp setting page and back again several times before accepting the new setting. the app has not been developed very well, as heating section seems seems to be more or less rushed into launch and has been poorly/unprofessionally executed. Eg. Apps day runs from 6.00-600 the following day so if you want to set the timer for Tuesdays from 5.30-745 you need to go into monday and set it for 5.30-6.30 then go into tuesday and set 6.30-7.45 ha ah what a joke the best bit is you cant do this for monday as sunday is the end of the week and wont cover monday 5.30 start time.

Rated 4 out of 5 by from Works well I bought this only a few weeks ago. Found it very simple to link to the rest of the lightwave setup. It works well - it is basically just a regular thermostat that can be controlled remotely. The structure of a running day being between 06:00-06:00 felt odd, because during winter, I like my heating on at 05:45-08:00 - but because of a bug - it doesn't currently let me programme an overlap (1. 05:45-06:00 -> 2. 06:00-08:00)...so I have to do 05:30-05:45 and then have 15 mins off until the 06:00 kicks in. Apart from that, it is fine. The iOS app is constantly improving - it's important to raise helpdesk tickets for annoyances/bugs you find so that they know about them.

Rated 5 out of 5 by from Thought I had bought a lemon at first, but works well now. I had a very out of date central heating system with just TRV's and no room thermostat. I liked the idea of this because it would wirelessly connect to a boiler switch, no wall channeling or cable runs. You need the boiler switch to go with this. I thought about pairing it with one of their relay modules, but have not tried it. The boiler switch also has the bost and standby buttons. It was a little temperamental at first, once I emailed their support line I was told that my link wasn't registered, thought it worked for lights and sockets over 3G / remote locations with WiFi. Anyway, they fixed it and now it works really well, especially since they updated the App in December 2015. You can ow select modes such as constant, running and stand by from the app, which is much better.

Rated 1 out of 5 by from Do not buy this product! I have used Lightwave lighting products for a while and found them to be excellent. The TRV's on the other hand are dreadful. Do not purchase this product. First off, it can only be programmed between 6am and 6am which means that if you have it come on before this, you will hear the motor go as the TRV turns off at 6 then turns on again which can wake you up from the next room. I will be returning this and purchasing something different.

I have a Worcester Boiler that already communicates via the Worcester Thermostat. Do I need the Lightwave boiler switch to make the connection work or is the Lightwave thermostat compatible with the boiler, thus not needing the boiler switch, only thermo

Asked by: Peter
You would need the Lightwave boiler switch as the Lightwave thermostat would not be compatible with any other switch type.

Can this item be used to control the temperature of an air source heat pump? The power source is obtained from a low voltage PCB which is fitted as part of the air source heat pump.
