Flower sensor Zigbee
Github How to compile Follow this article https://zigdevwiki.github.io/Begin/IAR_install/
Version 1 A lot of time has passed since the appearance of Mi Flora, but Jager never dared to purchase it. First of all, the fact that it was Bluetooth stopped, and this automatically created problems on a scale at home and the second reason was the cost, taking into account the fact that Jager needed 20-30 pieces. The decision, do it by myself.

FreePad Zigbee remote v2
Github
The first version of the Zigbee remote control is good, but this option is not suitable when mobility is needed. For this reason, a second version appeared, in which Jager tried to make a more compact version.
Since 20 buttons are not always and not always needed, Jager had to come up with a board design that allows you to assemble 3 versions of remotes, for 20, 12, and 8 buttons.

Geiger counter Zigbee
Github
We all know what radiation is and its harmful effects on humans. Since this danger is not tangible, in connection with this the idea was born to make an indicator for continuous monitoring of the radiation situation.
The device is not designed to measure the level of radiation in the epicentre of a nuclear explosion, but it allows you to constantly monitor changes in background values. This can be useful in the event of man-made disasters or when you or others bring something with increased background radiation into the house.

UPD: This keypad has appeared on AliExpress
Keypad has 8 buttons, two-colored led, and is powered by CR2032 lithium cell.

Reed Zigbee sensor
Github
Continuing the automation of the apartment, the idea came to make a doorbell button with ZigBee support. Sergey decided to use the factory model CACAZI A8 as a case with an acceptable cost - about 230 rubles at the time of original writing.
The heart of the device is the popular E18-MS1-IPX module. You can also use the version with a built-in antenna, but Sergey thought that the signal quality behind the metal entrance door would not be very good.
