ED-Eâ€™s first job is to monitor the house for extraordinary situations. It does this with a small suite of sensors. It can detect flame, sound, gas, air quality, temperature, and humidity. With this array, itâ€™s probably possible to capture every critical failure a house could experience, from burglarsÂ to water pipe leaks. It uploads all this data to Intelâ€™s Analytics Cloud where we assume something magical happens to it.
ED-E can also sense the state of other things in the house, such as doors, with remote sensors. The door monitors, for example, are an ESP8266 and a momentary switch in a plastic case with a lithium ion battery. Weâ€™re not sure how long theyâ€™ll run, but presumably the Analytic Cloud will let us know if the battery is low via the aforementioned magic.
Lastly, ED-E, can turn things in the house on and off. This is accomplished in 100% Hackaday-approved (if not UL-approved) style with a device that appears to beÂ a lamp cable fed into a spray painted Altoids tin.
ED-E wins some style points for its casing. Itâ€™s a very well executed hack, and weâ€™d not previously considered just how many awful situations can be detected with off the shelf sensors.
