Hi @gtortone I'm working on finalizing this node and I'm having some trouble with stability. The node stays alive from a few minutes to 30min and then stops communicating.
What kind of decoupling capacitors are you using in your setup?
I now have 2 pc 0.1uF, 2 pc 47uF and one 0.33uF.I use a HLK-PM03, a Pro Mini 3.3, and the NRF24L01+
Debugging output don't give me much to go in since it just stops responding.

Hi,
at the moment I'm defining some things in order to use RFM69 modules...
in the past, on my NRF24L01+ I was using 10 uF capacitor but I had same problems of "stop responding"...@gtortone My node has now been running for more then 40min since I added the 0.1uF and 0.33uF tantalum caps. I'm hoping this will be the solution for me since I have no tools to debug any disturbance like this.
EDIT: It failed again :(
-
Tried exchanging the NRF24L01+ with an RFM69 but it does not seem to work at all with this setup. Might be because the RFM69 is using the same frequency as the RFM12B or maybe I can not have the 2 in the same node because they are related.

I tried to add some more debug prints to your code today but if I add them to the wrong places the efergy receive function stops working and receives only 0 value. I guess it messes with the timing.

@korttoma Hi, I just returned to play with Efergy and Arduino. I realized that debug messages on UART reset the micro. Now I'm skipping (with a #define DEBUG and #ifdef) all debug messages and it seems to work fine. But take into account that now I'm not using any radio module... just to test the firmware.
-
:D What a coincidence. I returned to this project today also. Now trying to set this up as an Ethernet GW with local sensor without NRF radio. I still have to share the SPI bus with the Ethernet module though. I'll let you know how it goes.
I think I did try removing the serial prints earlier but I'm not sure..
-
The ethernet GW approach performs even worse than your original solution. I get one or 2 measurements and then nothing. Still responds to ping but no communication with the controller.
I don't know how to debug this since it just stops working. Is there by any chance anything in the code that consumes memory? -

Hi All,
First of all, great work man!
I was wondering do you know if we need to have established link between the wireless sensor and the receiver?
I only have the wireless sensor so I was wondering if I can use this without the receiver?
Any thoughts?

Hi,
I have been trying to receive the efergy signal using RFM69 and so far it's a dead end. I'm unable to receive any data on the RFM69 module.
Since you guys talked about RFM69 module here, I thought you might have some insight to share.
-
Any chance that I can see how you wired up the NRF24L01+? I bought the parts back in January 2017 and just found it in a drawer this evening. I assembled everything but the NRF24L01+ and I am a bit stuck right now.
BTW: Great build - I really hope that I will get mine up and running :)

@gtortone that is the same useless junk I got from e-bay at first, range is terrible.
This gives me some hope to get this working with the RXB6. I will test this as son as I can (might be a few weeks until I can).
@korttoma
I resume an old topic: i'm trying to receive data from Energy2 whith arduino connected to an RXB6. I can't receive any data, and i don't know how to substitute the code block related to RF12 with a correct one for my receiver. Can someone help me? Thanks in advance, Mauro -
Long story short, try 433.55 MHz
I tried for years to received my Chacon Ecowatt 800 (a rebranded Efergy 2 classic) data. I knew the frequency wasn't 433.92 MHz.
I lastly opened transmitter case to find which RF chip was used ... but I didn't get any datasheet for the "A71C03AUF" I found :(On last resort, I sought a signal on all "433.92MHz" ISM band (433.05~434.79 MHz, with sdr-sharp). I did find something centered on 433.51 (433.47 and 433.56, FSK?) MHz.
As for Somfy stuff (which uses 433.42 MHz), many generic receiver can't work with those *special" 433MHz frequencies.In the end, I tested this new frequency using rtl-433 and guess what, there's a working Efergy module ! Moreover, I did not make a great discover, 433.55MHz is well precised in the "efergy_e2_classic.c" module comments...
RFM69 or NRF24L01 may be frequency ajustable!
