Trying to put one of these together this afternoon, I have RFM98/SX1278 radios as we cannot use the 900 range in South Africa. How would I go about selecting the frequency... Please type very slowly...

Still did not find a way to extract the temperature value from the payload with the debug node. Tried several things with http://jsonpath.com/ without success. There I could only select count and data...

@johan Maybe the server does not accept packets without a "time" field? It should, "time" should only be included when you have GPS accuracy.
