What is it?

It's a fully assembled and programmed compact wireless devices, atmospheric pressure, temperature, humidity, weather forecaster, illumination, charts with 2.9" e-paper display, resolution of 296 x 128 pixels. The device has an industrial look, at least I wanted to achieve this. The sensor has good energy efficiency. Powered by CC2530 chip (Zigbee), works with Zigbee2mqtt, ZHA.

Why did you make it?

I am interested in making original devices that are not on sale.

Right now, I'm very interested in low-power, cost-effective wireless devices.

What makes it special?

• Wireless communication standard is Zigbee, works with Zigbee2mqtt, ZHA. https://www.zigbee2mqtt.io/devices/EFEKTA_eON29wz.html

• RF module EBYTE E18-MS1-PCB with CC2530 chip.

• The project uses 2.9 inch e-paper display from Dalian Good Display Co.ltd or e-Paper V2 from Waveshare Electronics.

• Long runtime with two AAA batteries.

• Consumption in sleep mode 1.8μA.

• The device has a temperature and humidity sensor SHTC3, pressure sensor bmp280, light sensor bh1750

• Charts of pressure, temperature and humidity for the last 24 hours are displayed.

• Weather forecast.

• Light level

• The case is printed on a FDM 3D printer, color: PLA Carbon Black. After printing, the case is further sanded and polished.

• Inside the case, magnet are installed for fixing to magnetic surfaces(optional).
