Temperature Web Monitor

Hello,

I'd like to start monitoring my house temperature using several espruino (one in each room for ex) so that the data is sent to a webserver (Raspberry Pi maybe?) and then I can monitor the reading on a browser.

The data would be used to adjust my pellet stove so that I can set the running programs better.

My questions are:

1. Is it something someone has done already? If yes, where can I find it?
   
2. If it is not something some has done, how can I set up the various espruino satellites to measure the temperature and send it via the wifi module to the webserver?
   
3. Is the RaspberryPI a good choice as a webserver?
   
4. What else do I need? I'm new at this so your help will be appreciated.
   
   

Thank you.
