Hi mscory,

It's been a while, but as far as I remember I was able to see the values as text in domoticz, but was not able to use those in events.

You can charge a battery, of course.....
A small dynamo will do the job.

It could be that transient sound waves are reflecting/scattering around and affecting the readings. The NewPing library states that 29milliseconds should be the shortest delay between reads.

Sound travels a little more than one foot in 1millisecond so you have an inherent delay in an empty garage; 15 feet each way, for example is about 30milliseconds from ping to read.

So, if you insert a delay(50) after you obtain the distance you may leave enough time for all of the sound to be absorbed or reflected away.

I second this. Built the sensor with a neopixel ring and the leds go berserk when I am about 3 cm away from the sensor with my hand.

Trying to get a Wiegand 26 reader to send the tagcode to domoticz.
Being not a wizard in coding, I think I got something wrong. I need to send the cardCode to domoticz to use in events, but the code appears in domoticz as "lux".
Does anyone out there knows how to correct the program (much obliged)

Thanks.
Knew this, but esp easy has native support for a wiegand reader, where mysensors has not. Had the software (included access control) up and running, but unreliable; as said before.
So I'm searching for a substitute for the esp.

finch666

Finally done away with esp sensors, wich to me appeared unreliable, and switched to the NRF solution. Stable as a rock so far, but I really miss the possibility to intergrate my wiegand door access in the network.
Anyone developing something like this at the moment?

Been running Domoticz now for a month and experimenting with programming sensors, I notice IDX numbers keep rising. Not used IDX's are not re-assigned by domoticz.
Is it possible to re-assign IDX numbers, so I won't run out off IDX's, or is it a none existing problem I see ahead?

finch666

It appeared my radio module wasn't functioning......
The nano gateway works perfect now.......
Thank you, TheoL, for your reactions!

finch666

Yep, even larger than 4.7 uF.
Could it be the 5V pin on the nano, not giving enough current?(a 3.3V regulator is connected to this pin). I thought this pin was directly connected to the 5V coming from the usb connection (powered hub attached). But if it isn't........ will be investigating that later this day...
This topic could be a lead; will try to get 3.3v directly from the nano.........

finch666

Trying to use a nano clone instead of mij current uno to establish a serial gateway to a raspberry. The nano however, keeps giving me a radio fail.
Checked the wiring 4 or 5 times, so that should be okay.
Searched the interweb for problems with these clones, but nothing useful came up, besides known problems with a USB driver, wich don't seem to be relevant, given the fact that uploading a sketch gives no problems.
Anyone else experienced such problems? Is there a solution? Or would it be much smarter to use a mini with a ftdi232?

The output on node 2 looks strange - ID 0 is (and should only be) the gateway!

I guess you mean node 1. And indeed, I really messed up the code somehow. Reloaded the original sketch and adapted it again, now everything works like a charm.
Thanks everyone for thinking along!

Node 2 was not powered when I monitored this node 1 output.

As a noob I ran into a problem with two nodes.
One (node 1) is running code to actuate 6 relays. the other one (node 2) has a relay and a pulse meter.
Whenever I actuate the relay on node 2 (connected to pin 4), then relay 1 on node 1 (also connected to pin 4) is actuated too. When I actuate relay 1 on node 1 however, node 2 is not affected.
Some how seems I'm overlooking something basic, but I can't figure it out
Node 1 is running the following code:


#include <MySigningNone.h>

  // Send the sketch version information to the gateway and Controller

  // Fetch relay status

    // Then set relay pins in output mode
