More usage examples or ?

[mr-sneezy]

I may have bitten off more than I can chew with my own fragmented coding knowledge (or lack of) with this version.
I've compiled the example ino and loaded to the Wemos D1 Mini, and connected to the Efergy E2.
In a serial terminal at 74880 baud, I see the ESP8266 serial boot message, then some initialization message from the firmware relating to the example settings, but then nothing else after that at all. No esp AP on air to connect too for configuration...

Have I mistakenly thought that there would be an AP on air to do the MQTT configuration etc, similar to what the original code readme describes, or is there a process I've not understood to configure wifi and MQTT settings for my network or get the Efergys TX ID with the library code ?

Sorry for the long winded question.

Yep, more examples are needed. This version 2 module is just the code for the Efergy Component, Wifi, MQTT is now not part of this code any more, so user can utilise the library how they need.

I have just pushed an example with Wifi and Slack if that helps. you'll need to load the MQTT module and add that back in if you need. Hopefully that gets you underway.

Documentation will happen at some point. :)

[mr-sneezy]

Thanks, appreciate the new example. Having a play to see how far into it I can get.

I use Telegram for event messaging out of Home Assistant with a ton of entities, not heard of Slack before tonight so will have to see I can adapt.

BTW, how did you derive your TX ID initially to enter that into setup ?
i.e. Efergymon.setID(,12,50,90);

[steven-geo]

Create a loop of Efergymon.getjsonevent() and print the json str to console, it will dump the packets received, and include an 'id' object in the json payload. I recommend labelling any transmitters you have so you can identify the tx id later.

[mr-sneezy]

I stripped out the Slack code from the example and tried to work this out, but then after three or four JSON beginners tutorials on Youtube and reading stuff the ArduinoJSON website I'm still not able to work out how dump the objects from the efergy library to the arduino terminal. I've not looked at any JSON before this and it shows.
I'll ask on the Home Assistant forum if anyone has used the library, as I think it might be able to used with ESPhome if values can be accessed within it and used as sensors...

[steven-geo]

Take a Look here for the JSON Object Names:
https://github.com/hardtechnology/efergy_v2/blob/master/efergy.cpp#L298

And here on how to access the fields
https://github.com/hardtechnology/efergy_v2/blob/master/examples/advanced_wifi_slack.ino#L68

That should let you get the data out into a variable of your choice. you can see in the example we are getting the 'id' object out of the son dictionary to use in our transmitter notification routine.

[mr-sneezy]

Thanks for the pointers, I'm trying this loop below currently as a general test if I can get the values, but getting 0's from all variables including the timestamp. (I've not shown the setup block as it's same as your examples minus the Slackpost code lines).

//  if (Efergymon.mainloop()) {
//    if (bool(Efergymon.getjsonevent()["changed"])) {
      bool tx_status = bool(Efergymon.getjsonevent()["status"]);
      int tx_id = int(Efergymon.getjsonevent()["id"]);
      int ts_now = int(Efergymon.getjsonevent()["ts"]);
      Serial.print("tx_id ");
      Serial.println(tx_id);
      Serial.print("tx_status ");
      Serial.println(tx_status);
      Serial.print("ts_now ");
      Serial.println(ts_now);
//    }
  yield();
//  }
}

[steven-geo]

I notice you have the mainloop commented out, this will mean packets are not getting received, so it is possible this is just looping through empty data - This would return Null/None/False or 0 depending on the data type. Otherwise looks sensible.

[mr-sneezy]

Modified to use the mainloop (I was not sure if I had to poll this or if it updated in the background).
Now have it in the loop, now however I get nothing printed after the IP address (from setup).
Does this mean my esp is not decoding ?
I have checked the bit frames out of the Efergy E2 with my oscilloscope and they are present on D0 of the Wemos at 2.5V and bit edges look sharp.

void loop() {
  if (Efergymon.mainloop()) {
//    if (bool(Efergymon.getjsonevent()["changed"])) {
      bool tx_status = bool(Efergymon.getjsonevent()["status"]);
      int tx_id = int(Efergymon.getjsonevent()["id"]);
      int ts_now = int(Efergymon.getjsonevent()["ts"]);
      Serial.print("tx_id ");
      Serial.println(tx_id);
      Serial.print("tx_status ");
      Serial.println(tx_status);
      Serial.print("ts_now ");
      Serial.println(ts_now);
//    }
  yield();
  }
}

[steven-geo]

You should be getting something. Can you set this in your Arduino code? This will dump out a heap of information about the Radio RX and decoding being performed for you. This might enlighten if we are beginning to decode anything and if there are errors.

#define DEBUG 1

[steven-geo]

Actually if you remove the 'if' around mainloop, as you won't have any Transmitters Identified, it will return a False and not run the code in the loop.
So run Efergymon.mainloop() but then just continue in the main loop, then you should see heaps with debug turned on as well, and be able to identify your transmitter.

[mr-sneezy]

Thanks. Removed the if around the mainloop and set #define DEBUG from 0 to 1.
Oddly, not much changed in the terminal. Here's a chunk of the dump from as it finished initialization...

[steven-geo]

Yeah, looks like you aren't receiving any data. Double check the inpin is set correctly to D0 and physically connected. I do notice it appears you aren't in debug mode still. When starting you should see a message like below on the console to indicate debugging is on
_debug=ON - T=Timeout, S=Start, b=bit, o=Rxtimeout, L=loop routine, E=End of Packet

[mr-sneezy]

OK I'll double check the signal on D0.
Here's the whole code (minus my real WiFi SSID and PW), in case I've dumb-assed it someplace.
Debug is set to 1.

Also tried reassigning the data input pin to GPIO4 (D2), compiled and switched the cable. Same result as above.

[mr-sneezy]

I tried something more basic today. Created a very small sketch that just reads pin 16 (D0 efergy signal) into a boolean and then right away sets pin 4 (D2) to that boolean in a tight loop. Digital equivalent of an analogue opamp 'follower' I guess...
The data is good. The CRO shows pin 4 output mirrors the waveform seen at input pin 16 (within the loop time), so confirming the Efergy E2 RX signal is being read fine by the ESP8266.
Now need to see why Debug is not working. Does it need to be also set in the Efergy library ?
