    I bought meself a Sigfox module a while back and started trying it out


    Registering the device was reasonably straightforward, as is interfacing it with the computing machine - I use a 3.3v FTDI cable for now and the cable provides sufficient power to run it.


    Coverage is decent in rural North Cork. Didn't have to place the antenna anywhere special to make it work.



    The biggest disadvantage seems to be the limited number of downstream messages (4x 8byte messages per day) and it appears to be the case that the module needs to request a downstream message before it can be sent.

    I havn't received a downstream message on it yet as I need to set up a script on my web server to handle the call


    Still if the device is sending out a generic stats message every 15 minutes and requests the downstream frame it might be possible to use it for switching on heating or other devices without relying on Wifi/GSM. Havn't yet discovered if requesting the downlink frame alone eats into the 4 messages a day budget. If it does it might be completely useless for home automation use


    Upstream is not so limited - 140x 12byte messages per day
