DIY zigbee sensor?

[martin3000]

I have built some sensors with wifi based on esp8266/esp32.
Now I would like to build my own zigbee sensors.
Are there any programmable zigbee modules with I/O pins?

Thank you!
He is working with windows software (IAR)?
This is funny :-)

I recommend this one: https://ptvo.info/

@frits thank you, I tried to flash the ptvo firmware, and after flashing I found out that the firmware does not contain a boot loader. So my zigbee stick is lost...

what modules do you use? I work with Ebyte E18MS1xx (CC2530 based) and flash them with a Raspberry Pi or aSmartRF04 clone.

If you have hardware that can flash it, then you can still recover. Not having a bootloader is only an issue if you don't have the right hardware. And as @frits seemed to be getting at, there are many choices these days where common hardware like a Raspberry Pi or even Arduino can be programmed to act as that special hardware. But even if not, some of the more common platforms you can buy pretty cheap programmers that will do the trick.

In my experience it's actually fairly rare to truly lock a device to the point where it's not recoverable. At least at this kind of DIY level. (Burning out a chip by putting the wrong power to it is another story... :) )

@frits I'm using a cc2652rb USB-Stick and I was flashing it via USB.

Do you have a raspberry pi and your zigbee stick has jtag header? Then you could flash your stick via jtag, look here: https://www.youtube.com/watch?v=0XOozGlbU7U

I had no time for testing my designs, but if the is someboby from europe interested it will raise my motivation:
(And i could share some PCBs of them)

for CC2530:
-8 Key Remote
-Test/Dev Board
(-Cc2538 coordionator)

Thanks ! -but you cant see other projects there than Homematic oder Zigbee Devices... They are actually only in my github repos... https://github.com/ranseyer?tab=repositories

@martin3000 I just noticed that PTVO firmware does support the "serial bootloader":

Anyway this feature is not documented too well.
