Harvia Smart Sauna Sensor Wi-Fi

The Harvia smart sensor turns any sauna into a smart device, including those heated with a wood-burning stove. After connecting wirelessly to the free MyHarvia app, you can monitor the temperature and humidity in real time from anywhere. The sensor is suitable for dry saunas and measures temperatures from 40 to 110°C. The app also estimates when the sauna will be ready and notifies you. For saunas with wood-burning stoves, it helps you know when it's the right time to add more wood to keep the heat stable.

Smart features and operational optimisation

Over time, the sensor learns how long it takes for your sauna to heat up. Based on this data, the MyHarvia app calculates when the sauna will be ready and sends you a notification. For increased safety, it detects and reports abnormal heating, such as if the door is left open. The sensor also records all sauna sessions and collects data on the sauna's behaviour under different conditions. This information helps you optimise energy consumption and makes it easier to plan maintenance, like knowing the right time to replace the sauna stones.
