@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.
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"...
Hi @korttoma,
the value 65535 or 32768 often is used as multiplier from sensor that send metric;
usually when you have to send a "small" float value (temperature, current) you can send it as integer
multiplied by a big constant instead of sending it with a float value converted in binary...
I just refined my formula with this that is more close to formula I found for my Efergy using a small
constant:
current = 18348 / 32768 / pow(2, 255-254 + 1) = 0.139 A
current = 17693 / 32768 / pow(2, 255-255 + 1) = 0.269 A
current = 28835 / 32768 / pow(2, 255-255 + 1) = 0.439 A
Hi @korttoma,
take a look to this decoding based on your collected data for 30W, 60W and 100W;
everything seems to be ok !!

Gennaro

Hi @korttoma,
happy to read that you are getting "reasonable" values from RFM12B !!
but I agree that in your case the decoding protocol needs some refinements...
just a question: your line voltage is 110 or 240 ?
take into account that from Efergy current sensor you get the value of "current" and
not "power" than for 30W expected value from data is (V/30) [Ampere]...
Hi, I have these modules:
http://www.banggood.com/433Mhz-RF-Transmitter-With-Receiver-Kit-For-Arduino-ARM-MCU-Wireless-p-74102.html?rmmds=search
the range is only few centimeters... I will try to do some antenna tuning but I don't expect any significative improvement.
If you want to try with your RXB6 module the code is always the same, you have only to remove the configuration code lines related to RFM12b configuration;
Hi,
you need to connect RFM12b module to Arduino following this schematic (you can avoid to connect IRQ line...)
http://jeelabs.net/attachments/download/331/jlpcb-128.pdf
after this cabling you need to connect RFM12b DATA pin to Arduino D3 pin (you can select a different pin but modify
code accordingly...)
only after this you can use the Mysensors-Efergy-e2 sketch (https://github.com/gtortone/MySensors-Efergy-e2) to get
RF data;
I tested my code with cheap RF modules (I received them some days ago) but the performance of these modules are very
poor... I will try to do other work on cheap RF modules in the future...
Thanks !
Hi @korttoma,
I did not tested cheap 433 MHz modules yet... I will receive a couple of them next week !
anywai RFM12b is a great module that has interesting features like frequency tuning and adjustable gain...
If I will have updates on cheap modules I will update this thread !
@skywatch
I meaning that often is also useful to check cable two (or three) times !
but if you already did it... ok !
@skywatch
Hi, options for "configure" are ok, I suggest you to double check your cabling !
You're welcome !
you can (re)run configure, make, make install when you want,
but I suggest to stop the mysgw executable before launch "make install"
if you did
make install
the mysgw executable is in /usr/local/bin directory then you have to launch it with:
/usr/local/bin/mysgw -d
@skywatch try to run it with "mysgw -d" .
Enabling debug mode you can see on console every message and diagnostics...
@korttoma said:
@gtortone very nice! I think I have one of these efergy e2s collecting dust. I would love to get more info on how you connected the RFM12B and where you purchased it from so I can get the correct type.
Hi, as you can see in photos I just posted, you need to connect DATA pin of RFM12B to a digital input of Atmega328P (it must be a pin suitable for interrupt).
RFM12B modules are not longer available... I have some of these (old) modules (all of them tuned for 868 Mhz) but I will do some tests with a cheap 433 MHz receiver (like this one: http://bit.ly/2gl6yXJ) or with a recent Hoperf transceiver modules (RFM69)
Thanks,
Gennaro

Some notes:
I'm using a RFM12B radio module tuned for 868Mhz equipped with 433 MHz antenna... but everything goes fine due to RFM12B has frequency tuning
I plan to do another setup using a simple 433 Mhz receiver or other Hoperf 433 Mhz receiver module (RFM12B are obsoleted modules)
Hi,
I just published on github (https://github.com/gtortone/MySensors-Efergy-e2) my last work about integration of Efergy e2 power meter with MySensors. The Efergy e2 electricity monitor (http://efergy.com/it/products/electricity-monitors/e2-classic) provides a sensor that wirelessly sends information about the amount of electricity you are using to the display monitor. The monitor converts this into kilowatt-hours.
This sketch use a JeeNode v5 (http://jeelabs.net/projects/hardware/wiki/JeeNode) equipped with 433/868 MHz RFM12B module (www.hoperf.com/upload/rf/RFM12B.pdf) configured in OOK mode to capture wireless data (on pin D3) and forward it through NRF24L01+ with MySensors library.
Comments and suggestions are very welcome !
Regards,
Gennaro
p.s. photos will be published soon !
Hi,
on gateway I'm using a NRF24L01+PA+LNA and everything works fine if I use NRF24L01+ or SI24R1 on sensor side.
If I replace NRF24L01+PA+LNA with something different (NRF24L01+ or SI24R1 module) the communication does not work...

I realized that if I disable broadcast search of parent node with:

the Si24R1 works fine !
but I don't know if this can be a problem for other features of MySensors...
@tekka Hi, thanks for the suggestion - I checked with MySensors dev branch from github but results are the same:

If I replace the Si24R1 with genuine NRF24L01+ everything works... (also with MySensors master branch)
Hi,
I just received five NRF24L01+ clones (Si24R1) but on website it is reported and I did not realize it when I bought these modules...
anyway is there a 'recipe' to have a Si24R1 working with MySensors ?
I tested them with ping-pong examples and they work fine... but if I try to use a Si24R1 with MySensors libraries it does not work..
