Sonoff gpio0. 3V, RX, TX, and ground Feb 8, 2020 · Hi All, I am new to the home automation space and would like confirmation on how to use the exposed GPIO pins on a Sonoff SV flashed with Tasmota. GPIO0 or GPIO14. I’m assuming 4 of those are the 3. This means that any connected device may "blink" when the Sonoff is powering up. A small green LED is onboard which can be controlled using PWM or GPIO commands. These are the differences between the two: * It can be powered by DC voltage * It has more usable GPIO pins - GPIO4 - GPIO5 - GPIO14 [Help]Remap GPIO0 button on Tasmota-ed Sonoff Basic for MQTT Is it possible to use the built-in button (used normally for toggling the relay) as a trigger to do something else in HA? If so, what do I change on the Tasmota configuration page and in configuration. 5 mm jack. mcu: esp32c3 board_build. DS18B20 have about 1 meter cable. Easily discerned from original Sonoff Basic since its using wires instead of thick solder traces for mains power. variant: esp32c3 # added the line below to prevent bootloops when flashing modern bin via serial board_build. 3v * Purple => GND * Green => TX FTDI to RX sonoff * Blue => RX FTDI to TX sonoff Jan 23, 2026 · - Sonoff switches appear to be locked - These have a Tuya CBU chip, but I am unable to flash them (tried unsuccessfully with some spares I had, they flashed but were unresponsive. x. The SV has 9 GPIO pins. Configure your smart switch module to work with Tasmota open source firmware. Sep 10, 2017 · Re: Sonoff basic - use RX and TX pins as GPIO #3 door tuxmartin » 08 okt 2018, 11:03 grovkillen schreef: 08 okt 2018, 10:30 Have you measured the pull-up voltage so it's close to 3. This also involves desoldering the entire CBU from the board, so I'd prefer a better option) - CloudFree has a 1-button switch that's absolutely perfect Mar 14, 2017 · GPIO-14 is the pin that can be used for this. flash_mode: dio esp32: variant: ESP32C3 board: esp32-c3-devkitm-1 framework: type: esp-idf sdkconfig Sonoff TH10/TH16 Information The Sonoff TH10 and TH16 are 10A/16A smart WiFi switches with optional temperature and humidity monitoring. yaml to first make HA be aware of it and then as the automation trigger? GPIO Layout ESPHome YAML esphome: name: basic-r4 friendly_name: basic-r4 platformio_options: board_build. Jun 18, 2020 · Hi all I’ve been expanding my collection of connected devices and am now playing around with the Sonoff SV. Later on, Itead made a few board revisions with noticeable layout changes. io lists out the available pins (note that there is no GPIO17 on ESP8266) I could not find a clear pinout anywhere. Although ESPHome. You have 2 choices when it comes to picking which GPIO to use. In my case this Sonoff will switch a light bulb, but for the input I want to have a doorsensor, via a reed-contact/magnet. One of RJ11 connector have 4k7 resistor - about 15 centimeters long wires from Sonoff PCB. If you have a Sonoff BASIC V1 devices GPIO14 is already presented on a pin header on the PCB next to the programming pins. 0 board into flash mode you need to ground GPIO 0 which is exposed on the back of the board and plug the board to USB Here is an image of the wiring Legend: * Yellow => 3. Does that mean that if I flash ESPHome to it, I would be able to use those pins to use as I²C’s SDA & SCL pin or to hook up an additional sensor like a Dallas DS18B20 or a flow sensor to it? Another quick question: Since the CSE7766 Power Sensor on the POW R2 only . Thanks to the incredible guidance by this community I’ve been able to connect it to a switch and a sensor on GPIO14 (like in the famous DrZZs garage video) My question is about the rest of those pins. GPIO Pinout Basic Configuration The following configuration also contains commented lines for adding a 1-Wire sensor via the 2. Sonoff Safe Voltage is almost the same as Sonoff Basic R1. Jan 16, 2018 · Introduction The Sonoff Basic is a relay unit to be used as retrofit. jllk pklx qppspn msd hxdvnpr glcy sjyc mkj kvs bqfqx
