Inverted RX serial in Berry

[jeroenst]

I want to read an inverted serial signal from a Dutch smartmeter with Tasmota using this device:

https://smart-stuff.nl/product/p1-dongel-slimme-meter-esp32/

The serial data is inverted by using the espressif function uartSetRxInvert.

How can I set Tasmota to receive the inverted serial data in Berry without additional hardware?

I guess this would need a change in Berry b_serial_init supporting the recently added invert option to TasmotaSerial()

Let me add this option, it's simple enough.

Please use the latest development version, there is now an optional argument to set to inverted:

# gpio_rx:4 gpio_tx:5

# normal mode
ser = serial(4, 5, 9600, serial.SERIAL_7E1)

# inverted mode
ser = serial(4, 5, 9600, serial.SERIAL_7E1, true)

# gpio_rx:4 gpio_tx:5

# normal mode
ser = serial(4, 5, 9600, serial.SERIAL_7E1)

# inverted mode
ser = serial(4, 5, 9600, serial.SERIAL_7E1, true)

its 4 years later, sorry for the bump,
but is it possible now to set 115200, SERIAL_8N1, 16, -1, true
aka rx 16 tx null signal inverted
or do i need a custom build, np there but where and how to set it?

[s-hadinger]

Those are in the standard builds. It should work. Just try it.

Thank you very much!

I'm going to test it this week.

hey man, I have the same dongle but I am not getting it to work, did you figure it out? so yes are you able to help me with mine?

Not yet, I want to pick up the development of the smartmeter script in the next few weeks
