Hello,
I'm a student at BUT Brno in the Czech Republic at the Faculty of Electrical Engineering. I am interested in IOT. At work, where I go, I want to suggest that we start doing Smart Home on your system. We often do electrical installations, and also consulting projects. I mean, if we learn with your system and implementation in HomeAssistant(We have built a few homes on HomeAssistant) I think we could buy products from you more often. So I would like to design my own smaller smart switchboard at home to show the company that this system has potential. So I guess my situation corresponds to situation B, start a Project.
If you grant the request, I would be interested in the KC868-A4.
Thank you very much for reading.
Sincerely Lubos Chmelař

Rebooting...

How solve it ? Is it hardware problem ?

I have designed a control system for a refit of my boat.

The break panel/control panel will be in the engine room, and would like to be able to turn things on and off at the helm, via a dedicated touchscreen.

There are 11 pumps, I would like to be able to see if they are turned on, for how long and if after a preset time, give out a warning.  

electrical layout

would love some feedback and/or corrections.  Trying to order equipment this week.

Hello everyone!

I would like to kinldy ask for some help with the KC868-A2. I am unable to communicate with the SIM800L module. I have tried to use the example code for KC868-A8S sms-relay and adapt it but it didn't work.

I have changed the Serial2 pins in "HardwareSerial.cpp" to RX2 34 and TX2 13.

Could you provide me with an Arduino source code for the KC868-A2 with the SIM800L module?

Thank you

Hi im very new to this and have been trying to find sample code to amend to do the following

Digital input 1 pulse count
 
Digital input 2 pulse count
 
Digital input 3 Reset Button 
 
If input 1 = input 2 + 100 pulses

Then switch com1 status to nc1

Hello.
I have already add my KC868-A6 by MQTT as binary sensors.

binary_sensor:

- name: 'a6-kcs-input-1'
  unique_id: a6-kcs-input-1
  state_topic: 'KC868_A6/B8D61A5C5304/STATE'
  value_template: '{{ value_json.input1.value }}'
  payload_on: true
  payload_off: false

How i can make work in modes "single click", "double click", "hold on"?

Hello need help,

I have this 2 sensor water level and pressure sensor but i dont know how to program it to ESPHome i cant see any code using this sensor in the internet hopefully anyone here can or know how to write the code. please see attached picture for reference.

I want to measure the level on how many percent of the tank like 100% is full and 50% half etc.

And the pressure of the water pipe like if 30psi to 70psi something like that.

Both output are 0-5V
My water tank is 3M height 

Thanks in advance

Could someone tell what is wrong in the code? it's not working with a hmi delta dop-107EV, I don't know what could be an error in the code.
