5 years ago So correct me if I'm wrong, but it looks like your objective is just to be able to read the state of the GPIO pins over MQTT, is that correct?
Try this: (which I am using for a garage door opener)

}I also suggest adding a transistor to the I/O pins you are using to attach to the garage door opener's limit switches. Even if your door opener is reading 3.3v, the unknown circuit doesn't give you any guarantees. You can use something easy like 2N7000, attach the gate to the switch on the garage door opener motor, source to ground (which should be common between the sonoff and the garage door opener, you can safely ignore the children who write the wiki at tasmota with their claims that it will catch on fire with a common ground -- its utter nonsense), and drain to the I/O pin on the sonoff.

Originally posted this in Gitter and it was suggested that I post it here.
Currently using a SonOff WiFi basic / Tasmota in multiple function mode as a Garage door sensor, opener and have added one DS18B20 sensor for temperature only monitoring. GPIO 4, 14 and a pulse for GDO. (IE: door open sensor, door closed sensor, push button pulse to open garage door and temperature sensor) It has worked fine over the last few months.
Over the last few months though have switched from Tasmota to Espurna firmware.
Automation sand box here using Homeseer MQTT, Home Assistant, Openhab, Domoticz, and Homegenie. (continue to utilize X10, UPB, Zigbee and ZWave). Personally like the Espurna firmware a bit better than Tasmota firmware. Where would I make a request for same functionality using Espurna firmware versus Tasmota custom firmware? I noticed it is much easier to solder modifications to the SonOff WiFi basic board versus the Magic Home RGB controller (which I am currently using with customized Espurna firmware).
In a recap the firmware would be multi functional for use with the modded SonOff WiFi basic device. Hardware modifications to testing SonOff WiFi basic: 1 - cut high voltage traces for relay to use low voltage 2 - soldered pins to RX, TX, Ground, GPIO 4, GPIO14. (GPIO 1,3,4,14) 3 - connected GPIO 3 to one door sensor, GPIO 4 to second door sensor, GPIO 14 to DS18B20.
Using MQTT to monitor status of GPIO 3 and GPIO4 and GPIO 14 and toggle relay for garage door opener.
This is a low cost WiFi basic combination garage door opener, door monitor and temperature sensor.
