Adding LoRa WAN support
Describe the problem you have/What new integration you would like Add support for LoRa WAN protocol like RFM95
Please describe your use case for this integration and alternatives you've tried:
it would be nice to integrate ESP between their self for various automation (like a far remote sensor)
Additional context
this is one of the primary library used on Arduino https://github.com/sandeepmistry/arduino-LoRa
In the german computer magazine c't was a project that contains an ATtiny and LoRaWan.
Maybe this can be used as an starting point?! Here is the link to the source code: c't Briefkastensensor
There is even a schematic to attach the LoRaWan module to the ATtiny which can maybe reused for the ESP32.
My use case: I have a remote network to supervise (in a basement) where there is no cellular or wifi network available (massive construction, tons of steel in the walls). I need to monitor the hosts in the network and report the data regularly. Power consumption is an issue here since the monitoring needs to be battery powered to work as well during a power outage. So any ESP is a must, i can't use a raspberry pi with HomeAssistant. LoRaWan does work here, so the transfer of sensor data via LoRa would work, when ESPHome can talk to the LoRa-Modem and transfer some payload regularly.
Hi there.
I have been trying to integrate Lora functionalities to Esphome on ESP32 TTGO OLED V1 boards.
I have had some success in sending messages. I am stuck on the receiver part.
Please find bellow my code. Please excuse the limitation of my skills in coding, I am no expert at all in this field.
Sender Side :

text_sensor:

lambda: |-
auto lora_text_sensor = new lora_sender();
App.register_component(lora_text_sensor);
return {lora_text_sensor};
text_sensors:
name: "Lora Text Sensor"
The custom sensor code is lora_sender.h
#include "esphome.h"
#include "LoRa.h"
#include "SPI.h"
using namespace esphome;
class lora_sender : public PollingComponent, public text_sensor::TextSensor {
public:
// constructor
lora_sender() : PollingComponent(15000) {}
void setup() override {
Serial.begin(115200);
Serial.println("LoRa Sender");
LoRa.setPins(18, 14, 26);
if (!LoRa.begin(868E6)) {
Serial.println("Starting LoRa failed!");
while (1);
delay(1000);
}
Serial.println("Sending data packet...");
}
void update() override {
// This will be called every "update_interval" milliseconds.
// Publish state
publish_state("Hello World");
LoRa.beginPacket();
LoRa.print("Hello World");
LoRa.endPacket();
}
};
This is obviously a very simple test case, as it pushes a simple string out. But I believe it is simple enough to adapt it to other cases.
I have validated that the messages gets properly sent by scanning RF with SDR.
Now for the receiving part, I am stuck on the custom text sensor definition. I don't know how to create a sensor that listen continuously (with continuous polling).
Any help would be appreciated.

For that you can override the loop() method.
Thank you Otto. Sorry for asking but can you point me to some example code ? As I said I am really coming back to coding, as I find your project worth spending some time upon... But I am absolutely a newbie in this field.
For example components/gps/gps.h - It's basically the same thing as here just that the loop function is now part of the component.
Thank you Otto I will have a look at this and let you know.
thank you for your codes, lefuneste82 and Otto winter's guide.
Can you share custom codes for the lora_receive.h
If Lora supports in ESPHOME , It will be more useful platform for the IOT things.
I wish I can integrate with Lora.
thank you for your trial Lefuneste83. : )
I'm also looking forward to get lora supported in esphome. I ordered some SX1278 modules (Ra-02 Ai-Thinker with 433mhz) to make some tests.
My goal is to connect two different home assistant setup's/networks which are some kilometers apart. Idea is to have a esphome node on each side (in their own network/own home assistant instance) which are listening to some home assistant (binary)sensors and pushing a message via lora to the other esphome node when a (binary)sensor changes. So it should be possible to mirror states from one home assistant instance/network to another. Great! Isn't it? So much the theory...
I think I found two very interesting libraries which could be useful for this:
https://github.com/sandeepmistry/arduino-LoRa
- Support for LoRa Semtech SX1276/77/78/79
https://github.com/jgromes/RadioLib
Supported modules:
- CC1101 FSK radio module
- ESP8266 WiFi module
- HC05 Bluetooth module
- JDY08 BLE module
- nRF24L01 2.4 GHz module
- RF69 FSK/OOK radio module
- RFM9x series LoRa modules (RFM95, RM96, RFM97, RFM98)
- SX127x series LoRa modules (SX1272, SX1273, SX1276, SX1277, SX1278, SX1279)
- SX126x series LoRa modules (SX1261, SX1262, SX1268)
- SX1231 FSK/OOK radio module
- XBee modules (S2B)
The second one is a bigger (not limited to lora) but very active project
My goal is to connect two different home assistant setup's/networks which are some kilometers apart.
Have you looked at the duty cycle limits for the 433mhz band? You might come close to exceeding that with a somewhat smart smart house.
Hey All, I wanted to share with you my custom code for a lora reciever. I'm using it at the moment as a gateway for two lora nodes, one for my power-meter in the basement, that is based on an arduino pro mini, and the second one as a mailbox sensor, that is based on an attiny84, similar to the one mentioned earlier from c't. I'm using the LoRa library for my RFM95 Lora modules and I included also some AES128 encryption with Crypto/CryptoLW library, the attiny84 limited the encryption to only AES128 due to RAM limits.

I wonder if the title should be changed to "Add LoRa support". Because as far as I understand is it all about LoRa here and not about LoRa WAN (yet).
Maybe the LoRa support could be added to the already existing remote_receiver and remote_transmitter components of esphome?
@Johni81 thank you very much for your sketch.
I was able to get a wemos d1 mini with a Ai-Thinker RA-02 433 Lora Module with SX1278 up and running as a receiver with your code. Little modifications for my 433Mhz module in lora_gateway.h are:
#define csPin 15 // LoRa radio chip select
#define resetPin 16 // LoRa radio reset // -1 for not in use
#define dio0Pin 5 // change for your board; must be a hardware interrupt pin
#define freq 433000000 // LoRa used frequency 433 MHz
#define SF 7 // LoRa used spreadingFactor // ranges from 6-12,default 7 see API docs
#define bw 125E3 // LoRa signal bandwidth in Hz, defaults to 125E3
#define sw 0x12 // LoRa SyncWord ranges from 0-0xFF, default 0x12, see LoRa API docs !!! MUST be equal on Lora sensor nodes and gateway
and my spi pins on the wemos d1 mini are:
spi:
clk_pin: D5
mosi_pin: D7
miso_pin: D6
My wiring:
ESP8266 - RA-02
Gpio15/D8 - NSS
Gpio13/D7 - MOSI
Gpio12/D6 - MISO
Gpio14/D5 - SCK
Gpio05/D1 - DIO0
Gpio16/D0 - RST
VCC - 3.3V
GND - GND
Now I wonder what's needed to get another pair of this (esp&ra-02) acting as a sender. My idea is to forward (binary)sensor data the esphome node is knowing (from local or home assistant) anyways.
Could this be possible? :thinking:
Any Chance this will get properly implemented in Esphome ?
@TessyPowder I guess the best would to support RadioLib but I could imaging that it is a bunch of work to integrate into esphome
Hi. I really like to have LORA for my home automation system. It makes my WIFI issues disappear in a second. Please add the support. Thank you in advance!
I have researched LORA a little bit. I think for starters, it would be nice to be able to initialize a LORA module as a sender and receiver. It would be nice to have something like LORA.send (STRING) and some kind of event when the receiving end gets a message.
That way you could set up a very simple LORA connection between two devices.
Do you think this is possible?
I know. So where would you go and post a feature request like this? How can the community fund this development? I think there are some guys interested in this. Do you want to do some kind of bug bounty or a kick starter?
Oliver
P.s. I already donated 50$ for this to Otto and I would add another 50 to some kind of bug bounty.
Best bet would be to drop into discord and possibly reddit and see if anyone is interested. As mentioned, radiolib looks like a promising way to integrate, but it would still take someone's time to actually add it. I think this is a no-brainer for adding functionality, but the issue is finding someone who is interested in actually doing the adding.
