@stubtoe said: I saw that the other day. It is pretty neat and given me a few ideas. I suppose I was also asking (although not very well worded!) where's a good resource when you want to design and manufacture your own bespoke PCB? Is there a good book anyone can recommend? For Designing a PCB, you can watch tutorials on YouTube (search e.g. for "eagle tutorial" if you want to design your board with eagle. I started two weeks ago and after one day of watching tutorials I built my own board in eagle A good address for cheap pcb manufacturers is http://pcbshopper.com/

I'm using a different approach using Google Charts, as outlined here. I run Domoticz on a RPi, and I've written a Python script to get values from Domoticz using JSON calls every 10 minutes, and write these to a .csv file, creating a new file each day. I then run a modified version of @stephenmhall's Python script, which creates an html file and calls Google Charts. One advantage of this approach is that you display the webpage in a local browser.

Fantastic. Thank you @niccodemi

@mfalkvidd I personally prefer to immediately correct the value when read from the dht: float temperature = dht.getTemperature() - 2.0; In case the dht returns a NaN value, this value will stay NaN even when 2.0 is substracted. But I didn't want to complicate things
