I want to be able to detect lake temperature. Would prefer to use a Wifi device, but would settle for a 433 or 900 MHz transmitter with a gateway.
I want to record the temperature locally. IE, not be reliant on a cloud service. I got burned by the whole Nest/Google debacle where they shut down the API, and ended up having to switch to a home thermostat that supports a local API.
I don't really care HOW the data gets stored locally (whether the gateway dumps to an FTP server, or I query it via serial, or it dumps to a log file) as long as there isn't a cloud server in the loop.
Has anyone found a device like this? I thought I had something with the Monnit Wifi sensor, but it seems like you cannot uncripple the device from their cloud service.
