  • Some of the buildings constructed using RAAC were only intended to be temporary structures, regardless of the knowledge of the material’s true lifespan.

    The Queen Elizabeth Hospital in Kings Lynn for example, was opened in 1980 and was intended to last only 25 years. But it is still being used today, 43 years later. It is finally being replaced, but only after it’s RAAC roof started to fail and had to be held up by hundreds of temporary supports.

    Buildings like this would have been replaced long ago if consecutive governments had not failed to properly invest in our public infrastructure.













  • You may get better results by using both indoor and outdoor lux sensors. Depending on the sun position, room layouts and window locations there can be a quite a difference in outdoor and indoor lux levels, which might interfere with your automations.

    I use a combination of Aqara Zigbee motion sensors, which also have a lux sensor, a couple of dedicated lux sensors, and my outdoor security cameras which have a day and night sensor.

    You can always try it with one and add more if you need more granularity. Every smart home is different.


  • Relying on sun positions and weather data can be a bit hit and miss for lighting automations. I originally used to limit some of my light automations to only turn on between sunset and sunrise - when it should be dark.

    But often when there was heavy cloud during daylight it would be dark enough to want lights, but the available weather data I had was never accurate enough to tell heavy gloomy clouds from lighter clouds.

    I added some light sensors to the mix and my automations have been a light more accident and flexible.
