Modern climate control makes us feel as though we have done just that... seized control of the climate. The mythology of total control for the sake of comfort is simultaneously a negation for us to attend, and care about local ecology. Haunted House explores how existing spatial technologies like the Internet of Things, might be reprogrammed, not in a logic of service provision, nor accelerated consumption, but rather towards greater contextual ecological awareness, kinship, and correspondence with more than human worlds. Smart homes, and the expansive field of wireless sensor technologies they're built on can do more than automate blinds and harvest user data. How might our habitats be embedded with a greater sensitivity to solar, meteorological, seasonal, celestial, migratory information etc? The intent is to derivé domestic IoT in order to "haunt" homes with a more-than-human presence, we for so long denied existed. Haunted house may be an installation, essay, or workshop.
