I have not tested this.
Great great work!
Would you mind sharing the flashing and pairing part a bit more in detail? I have never seen/done anything diy with zigbee devices and it seems like there is not much info for the ptvo firmware (apart from russian).
thanks!
Flashing is quite straight forward:
- prepare and download zigbee firmware with the PTVO program
- Flash CC2530 with CC debugger:
by using the free software from TI: SmartRF Flash programmer http://www.ti.com/tool/flash-programmer ( NOT V2 ).

Daaang and the e-ink model looks snazzy too!
As well as this “DIYRuZ Flower” Soil Moisture Sensor
PS: I posted a similar question in this Home Assistant community forum thread but got no suggestions there as of yet Zigbee flower sensors for soil moisture + light + temperature + humidity?
Thanks for the inspiration! I tried at first without the diode, and you’re right. It is not working. Hehe. But after adding it I think it is working just fine.

Tip is to also check out the related discussion here:
I’m looking for something like this too, but i’ve got 4 borders with plants outside. I think it’s cheaper to just buy 4 Mi Flower Care Plant sensors and replace battery every year instead of making this by my own, buy 4 cc2530, a IP67 box, power adapters, etc etc.
What should you do?
I personally went the Mi Flora way with ble integration. I would have preferred ZigBee but the lack of battery powered solution make me change my mind.
So far, the Mi Flora’s have been reliable since the Bluetooth integration revamped in HA.
