Re: Z-Wave Gateway
Since you say sou want to interface a PIC with that SoC, I'd say you kind of regard the ZM SoC like it is a merely some kind of transceiver. Z-Wave is actually controller, transceiver, radio, SDK, standard for messaging, standard for commands and sensors and much more... You can have good reasons to...

Re: Z-Wave Gateway
I can't help you with that ZM5304 because it uses a "serial interface protocol" and I have not read the docs in-depth (see ""Serial API Host Appl. Prg. Guide"". It is totally unlike the Z-Uno... It does not look like "building a device with the SDK either". I ...

Re: Z-UNO + RS232
Oh... Xon/Xoff protocol? Or maybe no handshake at all? Plausible.
I'm sorry to hear about those fried pins... Yeah... 1 k resistors...
A tiny (clone) logic analyzer might come in handy right now.

Re: Z-uno Nfc badge reader
Well... I thought the same, to make some super-slow-but-usable-transfer-protocol. Transmit to Z-Uno by setting multi-level (dimmer) 0-99, and reply by setting some dummy sensor. Device some handshake protocol. Hmmm... Probably just as fast as morse code ;-) Yes, unsolicited reports every 30 second. ...

Re: Z-UNO + RS232
Tht's ok, that is a "typical rs232 converter IC" According to the datasheet: "Operates With 3-V to 5.5-V VCC Supply" BTW I have not used RS232 in 10 years :-) my memory is rusty. There is a whole bunch of signals like CTS and DTR that might need to be set, before the UPS wants to...

Re: Z-UNO + RS232
Yes. The resistors are there, in case you accidentilly connect the uno to 5 or 12 V. Any partnumber on that chip.

Re: Z-Wave Gateway
My implementation is "power hungry" if you consider 40 mA at 3.3 V "power hungry"... I don not think you can power down the CO sensor. So trying to optimize the Z-Uno seems not worth it in this case.The Z-Uno is always on. You could make devices (actor + sensor) that run with les...

Re: Z-uno Nfc badge reader
I never saw a "text" variable. I think Z-Wave does allow a manufacturer to transfer arbitrary data, but it is somewhat special. But even If Z-Uno supported this... you still need some support on the controller, so that would be your next problem. If you own a Fibaro RGBW you might have see...

Re: Z-UNO + RS232
What chip is on that converter board? I suspect possible issues if the nominal voltage is 5 V. The Z-Uno outputs max 3.3 V (actually closer to 3.1 V). That might not be high enough to signify "1". Also, it does not accept more than 3.3 V on any pin, higher voltage with no current limit dam...

Re: Z-Wave Gateway
Yes, your Z-Uno can implement a relay and/or a dimmer and/or a sensor at the same time. For instance, I have a n RGBW light behind my TV and it also has a CO2 sensor at the same time.
