Hi all,
i'm looking for a cheap outdoor wifi thermometer and i simply can't find one
I need something wifi because i want to fetch informations from my nas and match them with my heating system.
Any suggestion?
Thanks

what kind of nas you have ? if it's running Linux and have usb port then maybe you can get an rfxtrx433 and connect that one to the NAS
now you can add some cheap Oregon sensors working on 433mhz to it.. an other pro is you can also add some kaku devices to switch lights etc

it's a qnap.
it has linux and usb, but it's not a standard linux so it could be not immediate to get something to work with it
i didn't know rfxtrx433, really nice.. even if it's not just "cheap"

My guess is that a combination of rfx433 and a Oregon sensor is going to be cheaper than any wifi enabled sensor you might find, specially if you also want a sensor for in the house or any other place. The rfxcm stuff only needs FT232 support to work, afaik that's in most kernels.

are you saying you have a rfx433 working on a qnap 412?
how do you fetch informations from the device?
thanks

You could of course just run a real distribution on it

Though at one point or another you'll realize that 'embedded' NAS devices have limited cpu and more importantly memory, also you'll lose the 'management' features (WebInterface etc) thus keep that in mind. Going the Raspberry-PI route might be easier to avoid any problems caused to your storage which you'll likely hold dear.

Please note that if a ready made Domoticz or other domotica package is not available for Qnap, you will have to compile such a package from source your self. I have many years thorough experience with Windows and moderate with Linux, still i found it to be a daunting challenge on my Synology DS412+

Buying a Raspberry Pi and instlalling a package like Domotiga seems easier.
