RFM95 (LoRa) support

[knopserl]

Hello, great project! I'm trying to integrate a couple of Xiaomi Mijia Temp/Hum BLE sensors with LCD display (link dbelow). I think people have alreayd tested it with this project. Finally I wanted to connect it with OpenHAB (via MQQT). SInce I have also other devces (LoRA) using RFM95, it would be great to have that in addition to the RFM69. The reason is, that I have a couple of ESP32 boards, which have the RFM95 (SX1276) on-baord (not the RFM69). A couple of that product are availbel (very cheap). Another quick question: If I want to use the W5500 instead of the W5100, does that work? Oth do we need another W500 library? Or should I use the ESP32 WiFI together wit Bluetooth instead of Ethernet? Does that work in parallel?

Here is the sensor I wanted to connect: https://www.banggood.com/Xiaomi-Mijia-Bluetooth-Thermometer-Hygrometer-with-LCD-Screen-Magnetic-Suction-Wall-Stickers-p-1232396.html?cur_warehouse=CN

Thanks, It is tested and working since V0.8

SInce I have also other devces (LoRA) using RFM95, it would be great to have that in addition to the RFM69. The reason is, that I have a couple of ESP32 boards, which have the RFM95 (SX1276) on-baord (not the RFM69).

I agree, it could be an interesting feature

If you have the choice between ethernet and wifi I would go for ethernet, you will get faster response time. Regarding the w5500 I never tested it, it could be interesting to have your feedback if you have one.

For questions and support I advise you to go to the forum/community, github issues are didicated to bug/feature request (and on per issue)

thanks for the quick response. I'll test it later with the W5500 (which I have at home).

I have seen, that I ran out of W5500, so I ordered W5500 and W5100 (the W5500 are the newer actually better LAN chips). However, the main request was rather the RFM95 (LoRa) support, as a couple of the ESP32 modules have it on-board (RFM95 or SX1276 which is the same), thus it would be a more interesting Radio than the RFM69 and has even longer range.

A first implementation tested on 2 TTGO LORA32 V2.0

@1technophile Can i use 433MHz RF libaries with TTGO or Heltec Lora ESP32? Because RF Receive/send Modules are really crappy..

If you mean to use the ttgo integrated transceiver for basics protocols supported by ZgatewayRF, the answer is not with the current code and I don't if we can hack the transceiver to do others protocols than Lora. By the way why do you think RF modules are crappy ? May I advise you to continue this discussion on the community forum, i don't want to hijack this issue.

@1technophile wow, I'm impressed, you did it! I will test it tomorrow. I have ESP32 Heltec and TTGo modules with SX1276 (equal to RFM95) on board which are the 868MHz versions of LoRa. I also have own modules with ESP32 and RFM95 modules (which are really good). Now with LoRa we have the longest and reliable range, a really good enhancement! With BLE I had the problem, that from my office to the kitchen (less then 8meters but 2 walls, I loose the connection to the Xiaomi BLE sensors. I'll give you feedack soon and thanks a lot. I hope that also others will like it!

Indeed it is an interesting add to OMG ! I wait for your feedback, at this time this a first implementation. There is place for improvments (like adding sender and receiver adresses) but I need to go in deep with lora protocol.
