# Wolf Climate Control ISM8

> Wolf Climate Control ISM8 is a Marketplace integration for Home Assistant. It has 73 installs sharing analytics, works locally and was last updated October 12, 2026.

Wolf Climate Control ISM8 connects Wolf heating systems to Home Assistant through the ISM8 network module. It works locally and exposes the datapoints that the ISM8 delivers over the network, and some of these can be written to. Entities appear as binary sensors, buttons, dates, numbers, selects, sensors, switches and times. Supported parts include heating units, direct and mixed heating circuits, a cascading module, a solar module, ventilation units, heat pumps and a controller. Setup runs in the UI, where the host and port the integration listens on are entered and only the devices actually installed are ticked, so others are not created.
