Data updates

The Huum integration pollsData polling is the process of querying a device or service at regular intervals to check for updates or retrieve data. By defining a custom polling interval, you can control how frequently your system checks for new data, which can help optimize performance and reduce unnecessary network traffic. [Learn more] the Huum cloud service every 30 seconds for status updates.

Known limitations

• The light and steamer entities are only available when the corresponding hardware is configured on the sauna controller.
• The steamer humidity level can only be adjusted while the sauna is actively heating.
• The target temperature can only be changed while the sauna is in heat mode.
• The integration applies the same safety measures as the Huum app. If a safety condition is triggered (for example, the sauna door is open), the sauna will not turn on.
