Abstract
Various arrangements for detecting and mitigating toxic gases are presented. Components of a home automation system may be used to monitor gas concentrations in home. Changes or elevated levels of gas concentrations may trigger mitigation or diagnosis procedures. Diagnosis procedures may include correlating the gas sensor readings with the activity of components of a home to identify possible causality. The activity of components may be changed and altered to test correlations or determine causality between components.
