Work Notes ========== DHD20160818 The methods: SortedMap getOptionalJSONStatsByUTCTimestamp(); SortedMap getJSONStatusValveElseBoilerControlByID(); have been removed from ETVPerHouseholdComputationInput and only: SortedMap getOptionalEnabledAndUsableFlagsByLocalDay() should be used for segmenting the data into control/normal. This is to clarify that the method entirely independent of the actual OpenTRV hardware and is more broadly applicable to any similar energy saving device.
