Hardware

@fhenryco I agree with you, I find it more simple to just remove the led. Cutting trace can lead to mistake (like you did on your first board) and there are a bunch of different promini clones, some might have traces using different paths than on the example.

@edsteve - thanks for reporting back - it might help someone else in the future :) Great you solved it.

I finally found some time to really look in to this 562 issue. I looked at the raw data in DataMine2 and I noticed that the 562 value appeared every 10 minutes on the minute. [image: 1480571212918-dm_co2.jpg] Then I knew that this value cannot possibly come from the sensor. I search around in my Vera device for a bit and I found some lua code that copied the "Variable1" value from the sensor to the "CurrentLevel" every 10 minutes. Then I remembered that in the previous version of this sensor the value was reported via V_VAR1 and I had to copy it to another variable in Vera to be able to draw any graph. The current version of the sensor reports the value directly to the "CurrentLevel" variable and the value 562 that was still in the old variable was copied over the "real" value every 10 minutes. I also previously had some really low values from time to time from the sensor mostly when responseHigh = 1 and responseLow = negative value so I forced the responseLow to always be a positive value like this: int responseLow = abs((int) response[3]); I will keep an eye on the behavior of the sensor now that I have finally removed the confusing 562 value.

@n3ro Couldn't you power the step-up from one of the arduino's digital pins? Then set the pin to HIGH/LOW to power the sensor on/off? Maybe it draws too much power?

@kimot Tried that. Ca't get domoticz to see the sensor.

@Cliff-Karlsson said: @tbowmo Like a "flex" sensor? Or loadcell? Like a flex sensor..

I think people are running MySensors on ATmega32U4 without any problems... I.e. @fleinze https://github.com/mysensors/MySensors/pull/378

Juts to leave a record about the issue. I changed the GW radio module with a NRF24L01 + PA + LNA one, powered by the AMS1117 and the ugly fix. Everything seems to working fine now. Thank you to every one.

You'll have to use separate gateways.

I did a similar project that is working well. Mine was powered all the time, so I didn't use the sleep code. The main reason I didn't was so that I could manually control the relay/light when there was no motion detected. It also allowed me to get continuous readings from the LDR so I could use that light level for other things if I ever wanted to. Here is a link to my project. https://forum.mysensors.org/topic/5243/driveway-motion-light . Maybe you can get some ideas from my code.

@Boots33 thanks that's really helpful info much appreciated. Now i need to decommission my Mega as my GW ready for RFlink and setup a new gateway.

There is an USB host shield: https://www.circuitsathome.com/arduino_usb_host_shield_projects/ This could be a solution.

@gloob I only commented out my network id/ passw/ and ip config A counter is included ;-) /** * The MySensors Arduino library handles the wireless radio link and protocol * between your home built sensors/actuators and HA controller of choice. * The sensors forms a self healing radio network with optional repeaters.

@AWI i've since done some more work on this and discovered the switched 3.95v didn't share a common ground with the rest of the circuit. So i ended up hooking up a DIL reed relay PRMA 0105 (5v) onto it, and used the relay contacts to connect to pin D3 on my nano. So i've got it operating that whenever the motion sensor is tripped it toggles my 1 channel relay board, but what isn't working is being able to manually switch it from in domoticz. Would someone be able to take a look at my code which i've taken from this thread My code is: /* DESCRIPTION Sketch for 1x relay with buttons bistable.

Hello For answering to pins connection in continuous mode i think you can connect it to the pins you want, and poll or irq. But, RFM69 driver for Mysensors uses Packet Mode. not Continuous mode.

@axillent thanks and what is the smd coil that you use?

@samdel said: how do you measur the noisyness Empirically, I just couldn't get it working.

Hello, Theese relays is already with triacs. You could look at themes in here: https://forum.mysensors.org/topic/4020/controlling-an-inductive-ac-load/2 ...and here: https://forum.mysensors.org/topic/3238/ac-light-dimmer-with-2x-triac There is discusion about it, and also shematics. Check it :)
