NRF52 MQTT gateway

Omemanti 10 Feb 2020, 14:21 last edited by

Hey all,
I want to upgrade my system to be able to use MQTT.

ATM, I'm using a ESP8266 (ESP-link) with an Ebyte NRF52832 as a mysensors gateway (LINK)

Can anyone point me on how to achieve this.
So my goal is:
Let all my NRF52832 mysensor nodes report to an MQTT broker (preferably bound to an ESP8266)

Who can point me in the right direction, or even better, tell me how to achieve this.

@NotYetRated Hope you'll find good uses and a fun time while building your sensors.

@Paul-Scarbro There are multitude of solution, but since we are in MySensors Land, let's do a MySensors solution. You'll quickly see that doing that adds a lot of overhead. We'll use an Arduino Nano or RF Nano if you're going to go whole hog. It can be run from 3.3V or 5V DC, not AC. The reed switch would be connected to an input of the Nano and one of the outputs would drive a relay. The relay would drive the chime. Your C++ program would be something like: #define inputButton 2; // connect reed switch here #define outputRelay 4; // connect relay to this pin see MySensors Relay example #define RELAY_ON 1 // GPIO value to write to turn on attached relay #define RELAY_OFF 0 // GPIO value to write to turn off attached relay void setup() { pinmode(inputButton,INPUT); pinmode(outputRelay,OUTPUT); // put your setup code here, to run once: } void loop() { // put your main code here, to run repeatedly: if (digitalRead(inputButton) == 0) { digitalWrite(outputRelay,RELAY_ON); wait(2000); // wait 2 seconds digitalWrite(outputRelay,RELAY_OFF); // now wait for door to close while(digitalRead(inputButton) == 0) ; //does nothing until reed switch opens } } There are some subtleties that I may have glossed over, but this is the gist. By looking at the MySensors Relay example, you'll see how to integrate this into a MySensors environment. That's where you'd want to get the RF Nano. I've made the assumption you're familiar with the Arduino IDE and you've looked into the MySensors environment.

@OldSurferDude yes, you are correct. this sensor is capable of 50A continuous, which safely I would make it working at 40A max., but for such an important load as in your case I would go for a beefier one, like the ACS75x, 77x, but at this point I would also change the node's form factor for space and insulation reasons. On my application on the RV I have a max. curr. of 13A running on a AWG14-16 cable (European rules for RVs), so I did not ask myself too many questions beside, of course, safety. About the signal, it will be a sinusoidal signal swinging around Vcc/2. Vcc can be easily measured internally on the ATmega328. On all my DC sensors I measure Vcc at every loop, just before measuring the ADCs. Honestly, when the space is not an issue like in my RV, I would rather use a ring core current transformer, and I would get rid of noise, response time, power dissipation, but over all no need to cut any cable. Long story short, it has been a nice experiment and I used it for 6 months, and then I switched back to my RF-NANO based RS485-Modbus - Mysensors bridge connected to an off-the shelf power analyzer. Just for fun I attach a pic of my 12Vdc sensors installed on my RV. Forgive me for the spaghetti wiring on the right side, but this is an area that needs improvement.
