L8-HAK Alarm Smart Switch

I had this for about 3 months now. I installed it myself, and its quite tricky because the hardware takes a big chunk of the box, and there are 7 wires thick wires to connect in very little space left (3 from the mains, 3 to the boiler, plus 1 extra earth to the box). The device has three entry points very close to each other, so you need to be very very careful, and do a neat and tidy installation. I get the feeling whoever reported the device burning maybe failed here.Once this is done, and it works... This device is a breeze. In 3 months it gave me no problems at all. I was concerned maybe I had to reconfigure the wifi or something like other smart home devices I have as light bulbs, but not at all, its been working perfectly since day one.The app is ok, the touch controls are good. You can use 30 minutes, 60 minutes, or a custom length of time of your choosing. In Winter I will schedule it, which I haven't tried yet.I cant fault it on any way after this testing period. I just hope I don't jinx now it after the positive review.

The switch is phyically well made, however the software is aweful and unreliable.I bought two of these as my hot water cylinder is fitted with two 16amp emersions. I setup the first one ok and connected it to the WiFi, and could see its IP address on my router. The second switch however connects to the first switch over the wifi using a proprietary mesh protocol, meaning it doesn't get its own ip address and has no direct Internet connection. So what's the problem with this, probably nothing if it was reliable but the first switch keeps loosing it's Internet connection and when it does this all of the other switches in its proprietary network become inaccessible too, such that I can't turn either of the emersions on from the app.The second issue is that there is no 'Matter' support or integration with smart home systems such as home assistant. Everything about this switch is proprietary rather than following industry standards.Overall, it's a well made device let down by poor, unreliable software and proprietary networking.Overall, its a well made device let down by poor, unreliable software and proprietary networking.

Nicely designed, easy to fit, connected to WiFi without difficulty, simple to navigate and set schedules. Works well, no internet drop, good power consumption data. Fully recommend.

This can replace a 3 gang switch simply, very easy to install and program. Great value also

Set up today great product and value for money

Purchased one as a trial to see how well it works.Overall I love it very well built very well presented.Very easy to set up - if you're not confident with electric get a electrician in!Taking the old one off and installing this took around 15 mins including getting it set up on the app (I am quite tech savvy so may take a little longer for other people)This only works on 2.4ghz wifi and if you have a mesh router you will probably encounter problems - I've always had a second router (not a mesh one!) for home automation with the 2.4 and 5ghz separate to prevent these issues.So far works without flaws and links to alexa without fail!Only gripe is it doesn't integrate with smartthings so I lose some very specific functionality around sensors and timers - but for most people I won't be an issueWould definitely recommend as it adds a nice modern touch and if you have more than 1 switch you actually know what you are turning on!

Some initial issues connecting to my eero6 router but this was resolved with the assistance of the very helpful support at Lanbon.The switch is now working as described and I am very happy with it.

Wifi bar code never worked. Keep saying searching for WiFi network although a full 2.4gh signal is available.I had to put the WiFi setting and connections manually using the onscreen terrible keyboard.I phoned technical support many times but no answer.They replied next day. I already left the site.
