@gohan said in Arduino Pro Mini Shield for RFM69(H)W:
If I remeber right that pin is used as input so the RFM69 is not receiving any 5v signal. In addition there are people claming they have the RFM69 module working on 5v on data pins and 3.3v on vcc, but I hardly suggest to do it.
thank you just what i thought .
about direct 5v on data...well... i seen a big red sign saying n :DONT do it! lol
Level converters are so cheap...that i ordered 5 or 10 thoguether with rfm69 board.
sorry about hijack this topic, i though i was on general discussion
@GLAB No worries, was in a similar situation.. My perspective was on what the Node could be made to provide, not what could be done within Domoticz to address the requirement - eg Had heard of Dummy counters but had no experience nor understood their purpose, nor had ever used scripts.
I had been sending a logical ON/OFF as well as a cumulative total from the Node and hit the same hair-pulling scenario as yourself.
Now only the ON/OFF is sent and the short script makes the transposition within Domoticz to a dummy meter (I think kWhr) using the internal clock in Domoticz.
Have fun
Use a latching relay. Here is one I found on Amazon. https://www.amazon.com/dp/B015MRQNXS/?coliid=I3LXTGKX4GEPUR&colid=31WWM91JAUE22&psc=1&ref_=lv_ov_lig_dp_it
If you are trying to use with existing 3 ways use https://www.amazon.com/dp/B015MSYQ8Q/?coliid=I3RP8X9OMYWU97&colid=31WWM91JAUE22&psc=1&ref_=lv_ov_lig_dp_it
Use an optocoupler to indicate lamp status...see the last diagram in this post. https://forum.arduino.cc/index.php?topic=435506.0
Thanks for your fast reply.
That sounds easy.
And you think that the communication between sensor nodes and Gateway are still possible via wired RS485?
I tried to find an example on this site for sending Information from Gateway to sensor nodes. (via SendMessage ?)
For example I like to Switch on/off an light that is connected to an relay board at my sensor node.
Communcation Flow:
OpenHab2 --> MQTT --> Gateway --> RS485 --> Sensor Node --> Relay Board
Currently I have an working RS485 Connection between my Arduino Uno's with the use from SoftwareSerial library.
During my testings I realized, that the message that I triy to send "Hello" will be sent to the other arduino char by char. Is that true?
Because I tried to raise up an pin on HIGH with "if(msg == "Hello")..." But it doesn't worked.
Will the sendMsg method from the MySensor library handle this out of the box?
Regards,
Simon

I found the solution on this page: http://mathertel.blogspot.com/2013/04/using-spi-bus-with-ethernet-sd-card-and.html
The key is setting the Chip Select (CS) line to be different for each module.
For the CC3000...
"#define ADAFRUIT_CC3000_CS 7"
Pin 7 is being used exclusively to select the Wifi module.
https://learn.adafruit.com/adafruit-cc3000-wifi/cc3000-breakout
For the NRF24L01+...
"RF24 radio(9,10);"
Pin 9 is being used for Chip Enable (CE) and Pin 10 is Chip Select (CS).

http://maniacbug.github.io/RF24/classRF24.html
The other SPI pins: CLK, MISO, MOSI, are shared by the two modules and get wired in parallel.
Hi do you still have a Gateway code when using CC3000 and arduino Mega or UNO(if it fits)?
