433 / 868 MHz common temperature sensors



  • Hello all,

    as I read this forum, it is an ongoing problem to battery power the sensors.

    Somebody told me that the temperature sensors usually found in "weather stations" you can buy everywhere often speak a very simple JSON protocol over 433 or 868 MHz. And since they usually don't have a problem being battery powered, they are probably an alternative, at least for measuring temperature and humidity.

    Did anybody already do some research connecting those kinds of sensors to a MySensors Gateway?

    Marcus.



  • I've one of these connected to MySensors - it's custom written code which I've lost 😕
    Anyway, using RX433MHz module it decodes binary sent code and reports as temp/hum sensor.

    Look for it, it's widely available for most of common sensors.



  • @MSchmidke Take a look at what Ray ( at rayshobby.net) has documented on this subject.
