## Questions & Answers

**Q: Is there any documentation on how to interface with this?**
A: https://www.hackster.io/makerrelay/esp8266-wifi-5v-1-channel-relay-delay-module-iot-smart-home-e8a437
Hope this helps you. take care.

**Q: I need a device, that when commanded, will send an electrical signal twice in a row. I want to wire it to a remote start which requires two button pu?**
A: If this button you need to control is a normally open pushbutton, you would wire the normally open relay contacts across the terminals of that pushbutton, and when you activate the relay you'll get one "press" of the button.  You would then write code equivalent to:
activate, delay, deactivate, delay, delay, activate, delay, deactivate.
which would give you your two button presses.  Experiment a little bit on how much delay is required, start with each occurrence of the word "delay" above being a 200ms delay.

**Q: Can i use this as a switch with 12v 1amp like sonoff sv**
A: The board requires 5 volts to operate, That said the contacts will switch 12 volts 1 amp.

**Q: All I need is a WiFi relay that alerts me when a float switch closes is there such a thing?**
A: This device is a relay controller, meaning it has an "output" signal.  You need a device with an "input" signal.  There are lots of other ESP8266 boards out there with "input" signals on board, and which could be programmed to do what you want.  You can buy those for about five bucks apiece, plus power.  You could run these off a USB cable with an AC/USB adapter "wall wart".
