ESP8266 + NRF24L01+ repeater node

vickey last edited by

Hi.

I want to increase the range of my existing EasyIOT server. I have wifi setup from my home to my farm using TP-Link 5210 cpe. Can I use ESP-8266 12E and NRF24L01+ as a repeater to my existing EasyIOT server which will be installed on my farm and will help to connect NRF24L01+ based sensor nodes installed on my farm to raspberry pi EasyIOT server installed in my home. Is this possible?

Idea came to me through Esp8266 Gateway example on forum.mysensors.org/topic/1870/esp8266-w...y-port-for-mysensors.

LAN8720A - will mysensors work with this module

Thanks for the answer. I meant that Mysensors has ESP32 support but only in terms of WIFI. It supports e.g. stm32 with ENC or W5500 modules - and the question is whether and how to add ESP32 support with LAN8720 module. I am not considering using ESPHOME or MQTT - I want to have native communication with the controller that implements my control schemes on its side. I try to program KC868-A16 but it does not matter - the question is whether such support can be added in a simple way.

@OldSurferDude jus request counter states from controller on each reset, worked fine with Domoticz... or save in eeprom but increase location every write, on power up/reset search eeprom for largest value stored and carry on from that location, one long integer will fit 256 times in atmega328(p) eeprom, is that long enough for you ?

@bgunnarb I like @eiten 's solution for you. Personally, I am not a fan of using cloud/public brokers. Thus I am curious about your system and there is something about it from which I can learn. I would like to understand why you cannot deploy your own mosquitto broker. I see your set up as 3 sensor groups defined by the channel used #define MY_RF24_CHANNEL ChannelOfSensorGroup Each sensor group has some number of sensors and one MQTT GW on ESP8266. On the MQTT side, do you distinguish between gateways by using a different host name? Something like: #define MY_MQTT_PUBLISH_TOPIC_PREFIX "mygateway-nOf3-out" #define MY_MQTT_SUBSCRIBE_TOPIC_PREFIX "mygateway-nOf3-in" #define MY_MQTT_CLIENT_ID "mysensors-nOf3" #define MY_HOSTNAME "ESP8266_MQTT_GW_nOf3" //#define MY_CONTROLLER_IP_ADDRESS 192, 168, 178, 68 #define MY_CONTROLLER_URL_ADDRESS "test.mosquitto.org" #define MY_PORT 1883 I must assume your controller (aka Home Assistant) discriminates between through which gateway the data is to flow by way of the different topic names. If my "something like" is correct, then changing brokers is changing the IPaddress/URL in your gateways and in your controller (though if the controller is Home Assistant, it may be a bother because the device-id's may change which will make a mess of all the work you've done in HA. This is why I like @eiten 's solution.) I hope it's all working for you again. OSD

@OldSurferDude well, the ESP8266 is limited to 4 TCP clients in arduino IDE. This can't be really increased. I did som experiments and you can set it up to 15, but after the 5th client on my web server, I got a freeze. Maybe you got something wrong. #define MY_GATEWAY_MAX_CLIENTS 2 defines how many controllers (eg Home Assistant) can connect to the gateway, not how many sensors/MySensors devices. And yes, you can have multiple TCP gateways in HomeAssistant. I got an NRF24, an RFM95 long range and a RFM95 short range gateway (all based on ESP32) on the same Home Assistant. Regards, Edi

Thanks, I'll keep this in mind if I decide to debug it. I realized that I am also tired of patching the gateway through to the doctor container inside an LXC so now I am looking at creating an esp gateway. Just need to check if I can find a pcb on here. Thanks again!
