Not sure how to ask this question but.......
I am working with Tasmota for the A6 and trying to understand how map the module parameters (GPIO1 to GPIO39) to the terminals of the 868-A6. I have not been able to find any documentation that describe the A6 functionally and which board inputs/outputs are mapped to the configuration table which is mapped to the ESP32 processor and determine which board inputs can be used for which sensors. IS THERE A DOCUMENT THAT EXPLAINS HOW THE TEMPLATE MAPS TO THE BOARD AND THE ESP32? E AND WHICH INPUTS/OUTPUS WORK WITH DIFFERENT TYPES OF SENSORS?
HOW DO WE DECIDE WHICH "GPIO" NUMBERS TO USE FOR SPECIFIC PORTS AND WHAT THEY SUPPORT?
THE ESP32 SCHEMATIC DOES INDICATED SUPPORTED PROTOCOLS BUT HOW DOES THAT TRANSLATE TO THE GPIO'S IN THE TEMPLATE AND ON THE BOARD?
I understand I2C and assume the display and external connector are wired to GPIO4 and GPIO15 and there are no other access points to that bus. Is this correct?
I understand the PCF8574 expander/multiplexer and the configuration with the 6 relays and the 6 DI ports that can be configured as INPUT/OUTPUT and through rules you can map inputs to drive the relays, IS THIS CORRECT?
SPECIFIC SENSOR QUESTION:
I need to us SEVERAL DHT11 temperature sensors , which GPIO's support that sensor? Its a digital data stream.
I assumed IO-1 or IO-2 on the board, is that correct? If so, should the KC868-A6 module parameter template be set to GPI01 and GPIO2?
On this template there is a "TX GPIO1" and a "IO GPIO2" that can be mapped to many different devices. Yet the input/outputs indicated for the A6 is "IO-1" and "IO-2". WHAT DOES THE "TX" AND "IO" DESIGNATIONS MEAN? IS "TX" MEANT TO BE AN OUTPUT IO OR ARE BOTH BI-DIRECTIONAL?
I different bus interface such as LoRa, RS22, Relays, etc. are clearly understood.
Are there 868-A6 specific videos and tasmota templates available? I have visited other forums and always come across the A4 and A8 but seldom find anything on the A6.
