do you have sensors on the Vera UI?
Try to debug putting Serial.print(Something) in places so you can see how the sketch progresses...
Yes all the sensors came up in the Vera UI, And looks like they work for some minutes
But when i push å button its looks like all things stop working, and after a reboot on the Arduino its working again for a short time and so on -

I edited you code so it can be read,,, attached.
Remember AutoFormat under Tools in your arduino menu
void loop() { debouncer1.update(); // Get the update value int value = debouncer1.read(); if (value != oldValue1) { gw.sendVariable(BUTTON_PIN1, V_TRIPPED, value==HIGH ?

So I have created a multi sensor that uses the DHT and motion to get Temp/Hum/Motion. Problem I have though is the update of the hum/temp. I have not been able to figure out a way to get a reliable update on those without blasting the GW/Vera with unneeded announcements (disable sleep function and it keeps updating pretty much every second). So right now the script updates the temp/hum only when motion is seen. I have tried a few things with my limited knowledge of arduino and can't get this to work properly. Can someone please take a look at this sketch and tell me what I am missing? If i change the variables for sleep at the end and try to do an interrupt and a sleep delay, i get an error.
-
Nobody wants to take a crack at this? I figured this to be a common combo and would really like to get it to work properly.

Note that the radio will get powered back up // on the next write() call. delay(1000); //delay to allow serial to fully print before sleep } -
Thanks that worked... and for my understanding... looks like your not really using interrupts at all? Looking at the code makes complete sense to me, and proves I was over thinking things on mine.
Thanks again.
-
is it the same process with the new 1.4 library version?
Could you please give us a exemple here or on github to have multiple sensor type on the same arduino with the new 1.4 library?
if it's the same implementation, we could write multiple "gw.present(ID, XXXX);" and send a message for each child ID type?
Thank's very much.

How did you get 3 options for the sleep interrupt? Whenever I would try and add the sleep_time option it would give me compile errors.

Thank you verry much, exactly what i need!For child's id, if you have two sensor you have to change the ID in the second?
Sensor 1 :
#define CHILD_ID_HUM 0
#define CHILD_ID_TEMP 1
#define CHILD_ID_MOTION 2Sensor 2:
#define CHILD_ID_HUM 3
#define CHILD_ID_TEMP 4
#define CHILD_ID_MOTION 5 -
@waynehead99 Are you using the new 1.4 Lib?
-
@waynehead99 you most likely need 1.4 Lib for the new sleep constructor. I have not used sleep on 1.3 so I do not remember what arguments you had available there.
I have also extended sleep with an additional constructor which @hek has pulled into the release branch of 1.4 that permits you to use two external interrupts with independent triggers for sleep in addition to a timeout. Great for nodes with multiple sensors that still run on battery. -
Im trying your code and its almost what im looking for.
I have two questions about it:
1 : Is it possible that the battery info has is own child id?
2 : Why dont you implement a light sensor like an LDR?I think that including LDR/light then you have the ideal multisensor ; light + temp/hum + motion + batt monitoring !
But for now im playing with your code and try to implement light. -

-
The battery percentage is associated with the parent Arduino Node in the vera UI.
I have some LDRs ordered from Ebay so that is the next step. I had previously used the BH1750 I2C sensor in a multi sensor with the 1.3 lib but I want to debug on its own as it seemed to be giving unexpected readings.@codenea The instructions are pretty much from the main page although if I get a chance I try to draw it up and post some pics. My setup not very pretty yet with perf board and jumper wires. A dedicated PCB would be nice.
