Guys, sorry, this is just what I need, but how do I run it? I'm using an iPad only these days, although I do have a Vera3 home automation system which runs code similar to this and links to my Netatmo at present (Vera runs Linux).. All I have it doing is retrieving the data from Netatmo so I can do things like turn heaters on and off. I'm now adding a Hydrawise sprinkler controller and would like it to be able to see my Netatmo - it gets it's data from Weather Underground. So, how does this script run? I do have a Samsung Galaxy Note 2 if there's an Android way of doing it. Last choice is to integrate Hydrawise and Netatmo - beyond my programming skills although I do have the Hydrawise API. Yes, I know all the words but couldn't write the code for toffee! I guess I can see this is a php thing but have no idea how it runs. Lastly, I do have a web hosting service which is also Linux based if there's a smart way of publishing it there. Many thanks in advance!

hi mfr
which free cron service can i use for your script?

Seems like this script broke. I've used the official measure api which works. You can get the changes from my fork.

I also added support for a rain gauge as shipped by Netatmo.

Yep, line #67 - last_data_store is no longer available. I've updated this in my fork.
