General Discussion

Short answer: No. Slightly longer answer: If you are sleeping to conserve battery you would need to power down the radio, so even if MySensors supported interrupts there would never be an interrupt because the radio would be sleeping as well. The power requirements for the radio in receive mode are too high for battery use. Long answer: Read the following earlier threads on the same topic: https://forum.mysensors.org/topic/2852/arduino-sleep-wake-on-interrupt https://forum.mysensors.org/topic/676/interrupt-on-recieve-radio-data/ https://forum.mysensors.org/topic/1461/how-to-sleep-the-arduino-but-still-have-it-respond-to-the-vera https://forum.mysensors.org/topic/1250/wake-up-over-radio/ https://forum.mysensors.org/topic/3100/low-power-servo-actuator/

@y4CdW42Ol8 Have a look at the examples as supplied with the mySensors library. Both ways are implemented extensively. The gw.sleep(...) function will be the way to go for the 12 hrs. you'd like to put the sensor asleep. This is used in many examples For waking up with interrupt have a look at the example for the power meter. It wakes up the sensor when an interrupt occurs. Be my guest to find your own way of programming this, but as @mfalkvidd already pointed out: MySensors has its own functions! Good luck, Boozz.

So with a little playing with the continuity tester I found a loose connection. I am not sure yet why I cannot do the upload with the UNO, but I got it to go with the serial adapter.

The controller can use the debug serial output from the gateway of type internal message subtype 9, I_LOG_MESSAGE, and report it in a log.

@dbemowsk Also works great in wine.

MySensors is primarily wireless, but not wifi (as in wireless IEEE 802.11). We do have wired options as well with RS485 / RS232 I do not think that ethernet (as in IEEE 802.3) is the best option for sensor networks for home-sensors, It requires too many wires to each sensor point, and too complex transciever hardware on each sensor node. RS485 is more suitable for this purpose.

In sweden this should be available on Clas ohlson, but you should be able to get this at almost any store that sells electric components.

@mfalkvidd said: I am using them at 12V so the power would be ~4W. Not too much but still enough to get the sink hot! The voltage makes no difference. 5A is still 5A. you are right :-) brain fart

if you put up some code I can have a look at it

@Øyvind-Lauritzen Debouncer Bounce won't work with sleep. Use a short sleep of 5 ms to debounce instead. Look at the binary switch sleep example.

btw, some of the RFID keypads that @hek mentioned supports the wiegand protocol and there is a arduino library available for that. https://github.com/monkeyboard/Wiegand-Protocol-Library-for-Arduino

Great, thanks for answers.

Problem Solved! When compiling, you must select Processor: ATmega 328 (3.3v, 8Mhz). Then the Serial Monitor will be fine at 9600 baud with the 3.3v Pro Mini.

Thanks for the link @mfalkvidd , ordered. Should be some fun projects for the kid and I over the summer.

To put it pretty simply, a gateway is a way to convert and move data from one protocol to another. For example, At some point I am hoping to create a MySensors gateway that will let the MySensors protocol talk to my RCS serial thermostat that runs on an RS485 serial network and uses a protocol written by RCS.

@y4CdW42Ol8 said: So in the build example, should the DO pin of the sensor be hooked to D2 of the Arduino? No, D0 on the moisture sensor is connected to D3 on the Arduino. See the wiring instructions: https://www.mysensors.org/build/moisture#wiring-things-up

Here is a package you can start without installing anything ;-)

Oh good, Thanks.

Found the problem. Bad connection to router. I am now able to interact with it. Ping did work as did netcat. Thanks again.
