I have two questions. 
First question, I have damaged the GPIO1 by having to many volts. It probably reached 7-8 volts. I'm using GPIO 1 and GPIO 2 as pulse counters. GPIO1 stopped working and will not read any more pulses. GPIO 2 still works. 

Are there any additional GPIO that I can use for pulse counting. I'm not using Wi-Fi, 485, or SIM module. If it's possible, where are the additional GPIOs located? And will be using a voltage divider to drop voltage down to 1 volt.

Second question, for the digital inputs. I was hoping it would trigger with 12volts. But it seems it will only trigger with ground. The reasoning is that i am using this in a camper van and I get 12-14volt DC as trigger. But it doesnt trigger, only with ground. 


Thanks again,

I want to control 2 different devices fans with 0-10v capabilities of one KC868-A4S but I'm not sure about wiring.

For the first fan from AFL Motors (file 122) these are the connections that I plan :
 - 0-10 VDC yellow on fan with AO1 on KC868-A4S
 - GND blue on fan with GND after AO1 on KC868-A4S

for the second fan from Aermec (file 22) these are the connections that I plan :
 - 0-10V IN V2 blue on Aermec with AO2 on KC868-A4S
 - 0V V1 grey on Aermec with GND after AO1 on KC868-A4S

Am I right or wrong ? If I'm wrong, what are the right connections ?

Thanks

I am looking for confirmation before purchase that I can use this board as I plannig to. Smile
So my plan is to use this board for central heating management. I attached a picture how does the setup looks so far.
I will use Home assistant and esphome.
As you can see I have 
- 4 24V AC valve.
- 5 temperature sensor (ds18B20)
- analog pressure sensor (SEN0257)
- leak sensor (just a basic contact sensor)
- opentherm adapter (this one)
- for network connection I will use ethernet

Do I need an additonal power supply (9-24V DC) to power my board? Or it can be power from 5V?

4x 24V AC valve: This is easy, They can go to the 4 relay. I think I will use the normaly closed terminals, in case of a board issue, the heating should not be affected. There is a separate 24V AC power supply, which only responsible for powering these valves.

5 temperature sensor (ds18B20): As far as I know these sensors has uniq id and can use the same pin, with one wire protocol. I can use the 3.3V output and ground from the board, and GPIO01 for the onewire.

analog pressure sensor (SEN0257): This sensor needs 5V can I get 5V out of this board? The output of this sensor is analog, so I can use AI1 for that.

leak sensor: This is just a digital sensor this is trivial too, it can go DI1 and ground.

opentherm adapter: This board need 3.3V, this I can get from the board. But also needs 2 free IO. Is there an IO I can repurpose in this case? There is only one free "bare" gpio left which is this case GPIO2. All other looks like has a special purpose.

I am really excited for this project and looking forward for responses. Thanks in advance.

SETUP:

  preferences.begin("almacenamiento-valores", false); // Start storage
  Serial.println("Escribiendo en NVS: 123");

  int valorLeido = preferences.getInt("offset", 0); // Reads the stored value.
  Serial.print("Leído de NVS: ");
  Serial.println(valorLeido); // Show the value that was stored.
  preferences.end();

Result I get on serial monitor:

Would you advice using a different library for storing values?

Currently yaml is like this:
Code:
uart:
  baud_rate: 9600
  tx_pin: 15
  rx_pin: 13
sensor:
  - platform: sim800l
    rssi:
      name: "Sim800L RSSI" 
      id: rssi
binary_sensor:
  - platform: sim800l
    registered:
      name: "Sim800L Registered"
but no sensors work in homeassistant....


I have a TTGO T-Call V1.4 board with the same sim 800l module.
everything works fine
The only thing is that there are additional module settings in yaml:
Code:
switch:
  - platform: gpio #SIM800_PWKEY
    pin: 4
    restore_mode: ALWAYS_OFF
    id: SIM800_PWKEY
  - platform: gpio #SIM800_RST
    pin: 5
    restore_mode: ALWAYS_ON
    id: SIM800_RST
  - platform: gpio #SIM800_PWR
    pin: 23
    restore_mode: ALWAYS_ON
    id: SIM800_PWR
