ESPEasy is really just a device that sends values from sensors, connected to inputs, to a server. Outputting data on ESP-pins is only limited implemented. From a server or browser you have a few html commands to manipulate outputs. (GPIO, PWM, Pulse and Servo are the implemented commands) I think wh...

Interesting, but can you be more specific where to put those lines in the switch plugin ?
Because line 201 is different in different releases.

Would be good to see a few lines before and after these two lines so it is clear where to put them.

@ tozett

Are you doing a commercial for AWS ?

I do not like to use a IOT server under control of an unknown entity.
My IOT server is a Raspberry Pi with Domoticz, 100% private. It can do everything I need and I can trust it because it is open source.

I do not know anything about MQTT.

I was thinking your problem is that the state of an output is not defined after a reset or wake_up after deep_sleep, because outputs may change during the reset process.
Apperently you are asking for something different, something that is not clear to me.

You can solve this with a supported hardware device. The MCP23017 is a 16 port I2C expander. http://www.esp8266.nu/index.php/MCP23017 If you reset the ESP the output states remain unchanged. Steady state current of this device is about 1mA (much lower than the the also supported PCF8574). So deepsle...

It is real easy, bend two pins up so they are not soldered to the board and connect them with a wire to Vcc. The only thing you have to check is that you compile with the option DIO and not QIO. You do not have to cut any board traces.

You do this mod ? http://smarpl.com/content/esp8266-esp-2 ... and-gpio10

Very easy to do when the flash chip is removed, it makes GPIO9 and GPIO10 fully usable, disconnects them from the flash chip.

I am wrong about you cannot use GPIO 1 & 3 for other purposes than I2C. You can connect a DHT sensor . Only hardware setting pinmode high or low is not possible in R80.

Not much chance to get this implemented in ESPEasy.
It would need an huge library of devices and commands.
Memory limitations I'm afraid.

Try it out , nobody has done this before with ESPEasy as far as i know.

After that tell us what your findings are.

I am curious.

When you do a I2C scan you should see address 0x40 with something like "SI7021 Temp/Hum Sensor, INA219, PCA9685" as description.
After adding this device you can use this command to set one output at a time.

At the current state of ESPEasy R80 you can only use I2C on the sonoff. GPIO 1&3 can be used for I2C but cannot be used as input or output. So you cannot attach a sensor like DHT11/22. As alternative you can use the forked version of R78, this version has fully functioning GPIO 1/3 (UART is swap...

@ polluz, yes it is possible.
