Migro wifi contactor Buy Migro for 240 volt Migro for 120 volt All in one: indoor-outdoor enclosure, contactor, Sonoff wifi module, antenna. Connect incoming wires to same side of contactor as Sonoff is connected. Connect load wires to opposite side of contactor. Use phone etc to turn load on-off. Your privacy is compromised when using wifi, and they control the product, and information coming from it. Migro comes with 2-pole contactor rated for 40 amp loads, contactor size about 3" x 2.6". The Migro contactor is not rated for 50 amp loads .... 50 amp contactors are 3-pole with minimum size 4"x3" Enclosure must be mounted to structure using screws etc. Cannot be mounted to unsupported siding, sheetrock etc without proper anchoring. Wires must be secured to structure. Extension cord is rated 300 volt and not approved for permanent electrical wiring. Use only 600 volt electrical wire as printed on side of wire. Solid copper is best for heavy amp loads. Stranded wire can splay apart and come loose over time.

WiFi
vs Zwave Wi-fi and zwave are different automation protocols. Z-WaveŽ Sigma Designs. Wifi bandwidth allows quick transmission of data, with more broadcast distance assuming all devices can reach router, and maybe wider functionality than zwave. Wifi has privacy issues, and devices from different companies require different app. Zwave works with phone or other device via in-home hub. Open-source zwave has been standard for decades. Zwave devices from any manufacturer will interoperate with each other, so it's one system. Each device can pass signal to next device, creating array of paths for signal. Zwave has some battery operated devices that can be placed anywhere and will boost signal distance. Depending on structure and placement of devices, Zwave might have more reliable operation with greater broadcast distance. Depending on phone, voice activation etc, Zwave might offer more privacy since information packets are tiny compared with Wifi.

Timer
on wall controls water heater 24 hour mechanical dial timer controls a contactor that turns water heater on-off. Timer fits into ordinary wall box used for switches, outlets etc. For home automation, substitute a wifi or zwave switch for timer. Hot water is scheduled using timer, which saves money each month, especially in homes with peak pricing. Reducing consumption is key for saving the most money and energy. Resources: See installation Image on left shows wall-mounted timer that controls my water heater. Eye-level installation: easy to change schedule, and reset after power outage Resources: See Family Chart for setting timer Off peak water heater options Other resources: Figure volts amps watts 9+ Ways to save with water heater..

 Larger imageNeutral required: Installing wall-mounted timer or home automation plan draws Black Hot and White Neutral from any nearby outlet box. Applies to all 120 volt programmable timers, countdown, wifi and zwave home automation devices. Rule of thumb: Neutral wires are white and usually covered with wire nut and pushed to back of box. Which boxes have a Hot and Neutral available? An outlet will always have Hot and Neutral. A switch box will always have Hot but not always Neutral. A ceiling box with light will always have Neutral but might only have Hot when light is on. Modern wiring code requires each box inside a new house to have both Hot and Neutral. Local codes vary. Some timers do not require a Neutral wire, but typically all wifi and zwave devices require a Neutral. If you do not have 120 volt available, then use ST01 battery-operated timer. If you only have 240 volt available, but not 120 volt, then you can step the 240 volt down to 120 volt using either encapsulated transformer or industrial transformer.

Fuse
and breaker
cuts off power when heat on wire exceeds rating. GFCI cuts power when a short to ground is detected. Arc fault cuts power with an arcing connection or short to ground. Ground provides direct pathway for electricity to reach soil or ground. Surge and arrestor protect from voltage increases caused by inductive loads and nearby lightning.
