Device sends %CO2% instead of the actual value

[Ed Davies]

Well, good in a way - it failed at or soon after 06:12:59 this morning.

Here's the last bit of logging my code got for this device out of MQTT (mosquitto). “ow” stuff is some one-wire temperature sensors and “cc” is a CurrentCost mains electricity meter. MQTT logged times may be a second or so late relative to the debug output; my logging code accumulates everything that happens in a particular second to make up a JSON line in the logfile.

Code:

{"_": "2016-12-30T06:01:09Z", "sophie": {"altitude": 28.49, "co2": 756, "pressure": 1009.83}}
{"_": "2016-12-30T06:03:30Z", "ow": {"28.B21AC8010000": 19.75, "28.D517C8010000": 19.875, "28.E3F2C7010000": 20.1875}, "sophie": {"temperature": 18.87}}

Attached is the debug output from just under half an hour before that (tail -n +20000 debug > debug.txt).

PS, device is plugged into a hub attached to me laptop so I could talk to it with the config utility. I'll leave it like that for the time being.
