A home automation platform, such as Home Assistant, allows you to make temperature v time graphs using sensors that you might place around the home. Monitoring temperatures allowed me to get my heating devices...
Yes. Below you’ll see how to control HomeEasy devices through Home Assistant and the RFlink receiver/transmitter. (This also controls other manufacturers’ wireless sockets). You’ll be able to create timers and automation to turn things...

rogerfrost.com is a compendium of ideas for using technology to find answers to sciencey questions. Since 1995 it has provided ideas to school science teachers. Since 2020 we’ve focussed on questions around the home with a new home automation section. So today we look at ways to measure and monitor around the house.
You will find everything here tagged and indexed by topic or technology.
Roger Frost was a writer from 1988 and this web includes many of his articles for magazines and newspapers. They tell how the early Internet developed; how real scientists work and how real people, like you might use technology at home or school.
