Broadlink · RM4 Mini
The BroadLink RM4 Mini is a universal infrared controller designed to centralize control of devices that use traditional IR remotes. It lets you manage TVs, air conditioners, projectors, fans, amplifiers, and other compatible equipment from a single mobile app. Thanks to its WiFi connectivity, the RM4 Mini can receive commands from anywhere through the BroadLink app and also integrate with voice assistants like Amazon Alexa and Google Assistant. Optionally, it can use the HTS2 accessory, an external sensor that adds temperature and humidity monitoring, making it possible to create automations based on climate conditions. It is one of the most popular IR blasters in the Home Assistant ecosystem thanks to its wide compatibility, local operation, and easy integration through the official BroadLink integration.
