Outside temperature and electricity usage

Our living room/kitchen is on the south side of our house, wireless outside thermometers can't reach it from the north side. But I have a server recording outside temperatures, and maybe a whole weather station in the future. So I only had to display the temperature I already had. We also had an old IPhone and a radio with IPhone dock. So I only had to write a small script that displays the current temperature in a web page and automatically updates. Then use the IPhone to display the page.

It also displays the electricity consumption in the last minute.

Maybe in the future I'll build a better app with more information, todays forecast or something. Data could be sent with mqtt maybe.
