TemperatureLowWarning #

Meaning #

The temperature in a room has dropped below 20 degrees Celsius for the past 6 hours. This is a warning threshold indicating that the room is becoming uncomfortably cold.

Impact #

Sustained low temperatures can cause discomfort for occupants, reduce productivity, and potentially affect the performance of electronic equipment. Prolonged exposure below 20 degrees Celsius can also pose health risks, especially for vulnerable individuals.

Diagnosis #

Check the current temperature readings from all Shelly H&T sensors:

shellyht_temperature_celsius

Identify which specific rooms or sensors are affected:

kubectl get pods -n iot -l app.kubernetes.io/name=shelly-ht-monitor -o yaml

Review the temperature trend over the past 24 hours to determine if this is a gradual decrease or sudden drop.

Mitigation #

Turn up the heating to increase room temperature. Check if heating systems are functioning properly and if there are any drafts or cold spots in the room.

Consider using additional heating sources such as space heaters or heated blankets if the central heating system is not sufficient. Check for open windows or doors that may be allowing cold air to enter.
