Atmospheric sensors/thermostat report 'nan' values #57

Open mkfink opened 6 years ago

mkfink commented 6 years ago

A handful of times per day some sensors (mostly humidity, occasionally temperature) report 'nan' values over mqtt. Happens mostly with the commons ground and ceiling sensor clusters and sometimes with the office thermostat. No occurrences from the fablab sensor cluster in the past 4 weeks. Home Assistant can't parse any of the values because an unquoted string is not valid JSON. Suggest re-reading the sensor or else just adding quotes in the case that the value is 'nan'.
