The WLAN-Thermometer



I started the project in february 2013 on www.grillsportverein.de as a very small proof of concept never even dreaming about what would develop out of this little seed planted in the heads of some geeky BBQ-buffs!

http://www.grillsportverein.de/forum/threads/wlan-thermometer-selbst-bauen-mit-raspberry-pi.181768/

It actually turned out to be of great interest to the BBQ-community and suddenly, a small number of developers from Germany and Austria teamed up and over the years added functionality and useablity to the product. Main goal was to have an affordable and powerfull tool to support grillers achieve their ambitous results in Q-ing.

The first PCB's were developed for the Raspberry Pi B and produced in China. Non-profit distribution of the PCBs very quickly created lots of builds all over Germany and Austria.

V3 "normal" and SMD-Version

With the new mini-version created by aschaefer85 integrating a Pi-Zero and adding 433Mhz hardwaresupport for future enhancements, the project now has reached a new level!

Nice stack of tech



Here is a picture how to hook up everything to the board:

The documentation can be found at www.wlanthermo.com . The problem is that it is not fully up to date due to a recent server-hack (shouldn't name it a hack here, ehhh ;-) ) and also due to the brand new mini-version-description not yet transferred from the BBQ-forum to the website. The handful of developers do this in their sparetime and capacity is limited. Please check the link to the Mini-Version under external links to be on top of (german) information for the moment.

A full translation to english is pending - I know this is a bad thing but we (or I) will work on it!

Update: We started with the Wiki on Github. Please check on a regular basis for updated information:

Going public on hackaday.io is the next step. We are very interested in the reactions of the rest of the world!

Thanks to aschaefer85 and Bjoern for bringing us to the next level.

Special thanks to my Austrian friends Phantomias2006 and JOE16 - without these boys we would not be where we are AT ALL!



Cheers
