 There are 3 types of ZigBee Devices:
-  - **Zigbee Coordinator Device:** It communicates with routers. This device is used for connecting the devices.

-In order to setup ZIGBEE you need at least one **ZIGBEE coordinator** device. In my case I use [[https://www.home-assistant.io/yellow|YELLOW]] from Home Assistant where a ZIGBEE module (Silicon Labs MGM210P Mighty Gecko) is on-board. In common use is also [[https://www.zigbee2mqtt.io|Zigbee2MQTT]] with a supported ZIGBEE adapter of your choice. I use this approach for debugging purpose only.

 In order to build a DIY Zigbee device (End Device or Router) we need a programmable Zigbee module. Several modules can be found in the market but I stick to [[https://wmsc.lcsc.com/wmsc/upload/file/pdf/v2/lcsc/2404011708_Chengdu-Ebyte-Elec-Tech-E18-MS1-PCB_C97344.pdf|E18-MS1-PCB]] from Chengdu Ebyte Elec Tech.
 It's based on CC2530 from Texas Instruments a bit outdated but cheap and easy to get.

 For DIY devices you may have to teach the coordinator software how to deal with your Zigbee data. In Home Assistant [[https://github.com/zigpy/zha-device-handlers|quirks]] bridge the functionality gap created when a DIY device deviate from the ZCL specification, handling deviations and exceptions by parsing custom messages to and from Zigbee devices.

-The final PCB is quite compact with a size of 44.5 x 24mm. On top you see the programming interface (J1) and a button (SW1). The yellow LED (LED1) is used an indicator. A 5V power supply can be connected via 2-pin JST connector (J7) or Micro-USB.  A 3.3V regulator is on-board too. The UART interface has 5V signal level and the I²C is standard 3.3V. The level of additional two GPIOs can be selected between 3.3V and 5V by jumper. All 4-pin XH connector (J3-J6) provide a power pin so that a sensor can directly be connected.

-For long I hesitated to step to ZIGBEE as the firmware development could become a challenge. There are a lot of step-by-step descriptions public but it's look like not to be an out-of-the box task. But I could find a couple of projects utilising the [[https://ptvo.info|PTVO firmware]]. The firmware tool allows creating a ZIGBEE device with easily configurable functionality, including inputs, outputs, ADC, pulse counter/generator, I2C, external sensors.

But I could find a couple of projects utilising the [[https://ptvo.info|PTVO firmware]]. The firmware tool allows creating a ZIGBEE device (has to be TI SOC based) with easily configurable functionality, including inputs, outputs, ADC, pulse counter/generator, I²C, external sensors.
 After some tests I was impressed and convinced how easy it is to setup a ZIGBEE device. This tools not only outputs the binary file (.hex) that can be directly programmed to the ZIGBEE module, it also generates the custom files for your coordinator of choice (e.g. quirks for Home Assistant). No need to program a single line of code.

 The setup of PTVO firmware is very easy. Just define P21 as counter and set the interval to 60 sec. Every pulse longer than 1ms at P21 will be counted.

 After pairing the PTVO firmware will send the counter value to the coordinator. In my case the sensor gives 360 pulses per litre. This calculation as well as the daily consumption can be easily done in Home Assistant. The following examples show the results:
