Custom sensors on pins?

Fri, 13 Feb 2026 03:31:20 +0800

New user here! I have not yet purchased the ALR, but am looking at purchasing for several remote sensors and the gateway. In reviewing the documentation and the youtube videos, it seems the individual pins are pre-defined sensors like the DHT. Is there a way to create a custom analog and/or digital sensor on the ALR? For example, if I have a High/Low signal?

Hi Admin,

Is it possible to use LoRa for indoor connectivity?

hi,

Even when the code apparently is uploaded I got this error message ( see last line )
can you please help on this matter?

all drivers installed

test with 3 different USB cables and usb ports

ALR LoRa firmware for home assistant enabled AUTO DISCOVERY

Thu, 05 Sep 2024 08:42:30 +0800

here is KinCony firmware for ALR LoRa board - ALR. it support control relay , monitor DS18B20 temperature and 4 channel analog input, 1 channel digital input state in home assistant by MQTT. You not need config any code for home assistant yaml. Because we have design firmware enabled MQTT auto discovery for home assistant.

  ALR-PCB-LoRA-Test-1.jpg (Size: 393.74 KB / Downloads: 1086)

here are two ALR board. one work as RECEIVER(gateway), another work as TRANSMIT(read sensor state, control relay), just set DIP switch on PCB, let two board same DIP state, so that they will communication with each other, easy!

  ALR-PCB-LoRA-Test-2.jpg (Size: 301.23 KB / Downloads: 1051)

RECEIVER(gateway) board's LCD displayer will show MQTT broker connection state, LoRa signal value and how many LoRa package have received.
TRANSMIT board's LCD displayer will show DS18B20 temperature value, LoRa signal value and how many LoRa package have sent.

chose RECEIVER board's firmware and set address to 0x0

  esp32-download-tool-transmit.png (Size: 52.85 KB / Downloads: 924)
chose TRANSMIT board's firmware and set address to 0x0

set router's wifi ssid, password, mqtt broker ip, mqtt port, mqtt username, mqtt password for RECEIVER board via USB-C cable.

config json command:
{
"wifi_name":"KinCony",
"wifi_psw":"a12345678",
"mqtt_ip":"192.168.3.124",
