Have fun with your Z-Uno!

No, use SLEEP. Your PIR element should wake up Z-Uno each time motion is detected I agree but I've build a device with a few sensors and an LED and in this case ZUNO_SLEEPING_MODE_FREQUENTLY_AWAKE allowed me to turn on the LED so it offers functionality that is available in no commercial product 8-...

BTW never inject current into a pin, I mean when you have no power to your Z-Uno then, for example, do not connect an input to a 3V battery without limiting current. The best thing that can happen is this... Your source connected to that pin powers up the Z-Uno (which might lead you to believe a Z-U...

Thank you for reporting back! Glad you have found a workaround with "Smart Implant".

IIRC I've fixed it like this, but it was a long time ago... I downloaded sdcc 64bit for mac. Possibly I used "homebrew" to do that but I cannot remember. The I searched where Arduino puts the sdcc compiler in its tool chain, in my case the path is: /Users/peter/Library/Arduino15/packages/Z-Uno/tools...

Make sure to set up Multichannel Association to 1:0 and not just a simple Association to 1 Neither HC2 nor HCL or HC3 allow you to enter associations like that (using numbers), but HC2 and HCL have columns marked "S" for single and "M" for multi which is the equivalent. I've tested this after a use...

I don't define pins in this sketch, this is intentional. I only send "on" or "off" to 7 sensors at regular intervals... To prove that the HC2 and Z-Uno can "understand each other", but only if I remove both checkmarks in S and M column, save, and then add M checkmark! If you want an example of "read...

No issues with "Sensor Binary"... Works for me after I remove both checkmarks in S and M column, save, and then add M checkmark, save. Don't forget to exclude your Z-Uno, then flash sketch and re-include before trying my sample sketch... All seven (or eight if you count "root" sensor object) devices...

Thank you for reporting back. If I find the time, I'll test with ZUNO_SENSOR_BINARY_MOTION or something similar

I don't have a "Sensor Binary" test sketch, but I do have this "Switch Binary" test sketch, I've extended it to handle 7 switches... Works for me after I remove both checkmarks, save, and then add M checkmark, save. Don't forget to exclude your Z-Uno, then flash sketch and re-include... MultiChannel...
