off / delayed) – Hot water pump steering – Lights – Window blinds – Garage gate – Main entrance gate • Scheduling: – Define schedules for any switch (with delay), eg. blinds up every 6AM • Sensors: – Current temperature – Charts • History: – Switches state – Temperatures
via Ethernet (ready- made board) • Switches module RM8 5V controlled via GPIO • 12V relays for switching 230V in window blinds • Dallas ds18b20 one wire temperature sensors • Bread-board and bunch of wires
- “delayed” on / off • MongoDB – history of sensors and switches • Memcached – cache switches status • Crontab module to setup schedule (via internal curl to API)
/ queue) • Don't play around with higher voltages unless you're pretty sure what're you doing... • Be prepared for frequent and random restarts (and SD cards failures…) • Don’t use GPIO pins which have different initial (on boot) state than you like to use with your peripheral device • There plenty of ready made components, soldering is often last thing, if you want to get things fast
