Very good idea ! I already use Slack at work and find it very useful.
I would definitely join this room. Here is my e-mail : firstname.lastname@example.org

RE: Powering my node
Actually this one will receive even more sensors (a rain sensor and a photocell). I was thinking about powering it with a LIPO battery and a solar panel. By the way, any tips on what components are needed to do that ? It is not very clear for me...
Anyway, my original question, as well as the answer, are still valid for other nodes I intend to deploy in the house and to be powered with AA batteries.
Powering my node
I built a small weather station with a DHT22 and an atmospheric pressure sensor, an Arduino Pro Mini 3.3V and a NRF radio. I did manage to make it work with a 9V battery to power the Arduino board, but if I replace it with a pair of AA batteries, it doesn't send data anymore...
However I keep seeing projects using only 2 AA batteries to power simple nodes like this...
Any idea what I did wrong?
By the way, I tried to put a 4.7uF cap between GND and VCC pins of the NRF, but it didn't solve the problem...
Hello there !
I am currently testing a simple setup with on one side, a RPi running Jeedom with a Serial Gateway plugged in, and on the other side a Relay + Actuator node. This node uses a modified version of the example code, so the button directly controls the relay, then notifies the GW of the new relay state, instead of asking the GW to toggle the state.
My problem is the communication works well one way: from the node to the GW, as when I use the button, I can see the widget in Jeedom reflecting the new relay state. It always works.
But when I try to use Jeedom to send commands to the node to switch the state (I did not changes this part of the code), the node receives nothing (checked with the Serial monitor) and the GW log in Jeedom shows this:

I'm talking about the last 3 lines. What is above is the working part (GW receiving info from the node).
Here is the configuration of actions in Jeedom :
About an hypothetic range problem, I tested the two devices being as close as 30 cm from each other...
Any idea what could be wrong here?
