For this initial test I am uploading my shack room temperature to thingspeak.com in the "ZYW Home" channel.
The circuit reads temperature every 60 seconds (almost 62 seconds, actually) and uploads it to the cloud. The temperature sensor is a 1-wire DS18B20. The dashboard shows the average temperature in buckets of 10 minutes and how many measurements have been made since power-on.
Incidentally the latter number provides two more information:
- power outage at home if "cycles" restart from 1
- xDSL outage or problems if there is a gap or no data upload
