I recently purchased a Pioneer wall mounted ERV ( Pioneer ECOasis 150). It utilizes a re-branded / re-skinned Tuya app, but I was able to successfully get it setup and working with the Tuya Smart Life app (by volcano technologies).
Using the Tuya integration, I am able to add the device to Home Assistant. The issue I am facing is that the Tuya device type (Ventilation System (xfj)-Tuya Developer Platform-Tuya Developer) is not supported by Home Assistant.
Scenes work, but I would prefer to control the device directly via HA. Please add support for the “xfj” device type in the Tuya integration.
