I totally understand, I have had similar issues, I usually tried some workaround, like, defining different channel types (eg a "multilevel switch" or "multilevel sensor" might do the trick, not sure what you want to do) and accept that the GUI might not be 100% correct, but at le...

The Z-Wave specification is not a single standard, frozen in time. It evolves. The specification, in total, is more than 1000 pages... There is room for interpretation. Z-Uno is unique because it allows you to make "arbitrary devices" that do not resemble anything else. Blame Fibaro, blame...

Try to change the associations, the "M" and "S" columns on HC2 are important, but unfortunately at the moment I can not re-check what I wrote earlier about this, because my HC2 is disconnected

See https://z-uno.z-wave.me/technical/power-supply/ If you remove R12 then you effectively remove all regulators to the MCU, this is what reduces the standby current. Indeed, you have to power via the 3V or BAT pins (top of the board near USB connector). From the top of my head, 15 mA seems "no...

Ah. What did you do before it got into this state? Overvoltage? Apply more than 3.3 V to the pins? Or interrupt flashing while trying to update a sketch or the bootloader? If it is overvoltage then your chances are slim. If it is a problem with the flash image then you might have a tiny chance, Ther...

If it is doing all that blinking, then IMHO it is not dead. I think your user sketch hangs. By recovery procedure, you mean this? https://z-uno.z-wave.me/getting-started/troubleshooting#Z-UnoHangs "To go into Rescue mode hold down the Service Button and then hold down the Reset button, wait for...

Can I "talk out loud"? ;) Does it have to be precise? If eg you wanted to display a time on an OLED in HH:MM format then I think the following might work: define 2 "multilevel switches" and one binary. Every 30 seconds toggle the binary switch, to trigger a scene on your controll...

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...
