Device Profile: Convergent Muse touchscreen automation controller

Dec 7, 2007 — by Eric Brown — from the LinuxDevices Archive — 1 views

Convergent Living used Linux to build a WiFi-capable automation controller aimed at letting users control HVAC and multimedia equipment in homes or offices. The handheld Companion Muse is one of several energy-efficient, Linux-based touchscreen controllers from Convergent, whose products range from kitchen computers to… flatscreen TVs.

The Muse and other Convergent touchscreens are intended to be sold and installed through professional integration markets, says Convergent. Once configured, they are designed for use by homeowners, with additional applications in corporate boardrooms, bars, restaurants, and other public venues.

With the Muse, says Convergent, home owners can access the Web from anywhere in the house, while controlling and programming their HVAC, stereo, security systems, spa systems, and other home devices. The Muse can work with existing devices or be extended via “network translators” that enable control over devices with serial or IR interfaces.

According to a company spokesperson, however, the Muse “is not advised as a mission-critical standalone controller because of the inherent unreliability in WiFi and li-ion batteries.” Convergent recommends it instead as a mobile client adjunct to the company's Companion 15, Companion 8, or SideKick master controller.

What's under the hood?

Formally referred to as the MU8B005, the Companion Muse is based on an 800MHz LX-800 Geode processor. The Muse is equipped with a 8.4-inch TFT Active Matrix 800 x 600 SVGA LCD touchscreen, and includes an embedded 802.11b 2.4GHz Wi-Fi card and 16-bit audio with a built-in speaker and headphone jack. The 7.9 x 9.6 x 1.1-inch, 1.9-pound controller is encased in a magnesium-alloy housing, with optional rubber grips. It comes with VESA wall mounts and a recharging desk cradle with power connector. USB ports are available on both the unit and the cradle.

The fanless device includes a four-way rocker, which, together with four front-mounted preset buttons can be configured to control tasks such as screen on/off, go to browser home page, and volume and playlist controls. They can also be set to operate garage doors, lights, and alarm systems.
