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". ## Frequently Bought Together - HiLetgo ESP8266 5V WiFi Relay Module TOI APP Control for Smart Home Automation System - Ewelink WiFi Wireless Smart Relay Module USB 5v/12v/24v/48v Inching Selflock Remote ON Off Power Switch for Access Control,Turn on PC, Compatible with Alexa Google Home - MHCOZY WiFi Wireless Smart Switch Relay Module for Smart Home 5V 5V/12V，Ba Applied to Access Control, Turn on PC, Garage Door (5v) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sg/products/44238856-hiletgo-esp8266-5v-wifi-relay-module-toi-app-control-smart](https://www.desertcart.sg/products/44238856-hiletgo-esp8266-5v-wifi-relay-module-toi-app-control-smart) --- *Product available on Desertcart Singapore* *Store origin: SG* *Last updated: 2026-09-03*
