ZigUSB was developed as a device that allows you to control and monitor the power of a device connected via USB.
Using this device, you can remotely control the power of the USB port to turn on or off the connected device. And also monitor the current voltage and current. And it’s not a bad Zigbee network router.
Frequent use cases: converting a “stupid” USB lamp into a “smart” one; connecting modems / sticks / adapters, which sometimes require a power reset; monitoring the current consumption of any connected device.
layout: page hide_title: true hide: true About This adapter is designed to connect an OpenTherm compatible boiler to any TTL port (TTL-USB, ESP8266, ESP32, Arduino, etc).
Same size as popular RS485-TTL module for more compatibility.
As software part you can use:
OpenTherm gateway for HomeAssistant - very intelligent OT control firmware 🧠 Tasmota OpenTherm - perhaps the easiest way to connect the boiler to your smart home system 🏚 Opentherm IO library for Arduino or OpenTherm Arduino/ESP8266 Library (slave mode only)
ZigUNO is a development board for creating DIY Zigbee devices based on Ebyte E18-MS1 module (CC2530)
Physically, the board is compatible with all shields of the Uno form factor. Finally you can use countless old Arduino shields 🤣
As a firmware, it is proposed to use:
Zigbee configurable firmware PTVO 🚀 Develop your own using ZigUP or one of the various DIYRuZ projects as examples Usefull links A beginner’s guide to using PTVO is available on Habr (in russian) A beginner’s guide to developing your own Zigbee firmware is available on Habr (in russian) A complete guide showing how to install IAR to start developing your own firmware is available on ZigDevWiki ZigUNO is certified open source hardware project Overview v1.
Lumi Router This is fork of Lumi Router JN5169 firmware for use with the LM15-SP-WM module used in the Xiaomi Smart Plug (ZNCZ02LM).
Also it can be used with any other JN5169 based module.
The only difference is the ability to reset the device using a button on DIO 0.
In the original firmware, all control takes place only through the serial port.

Board v2 available at GitHub Today I want to share with you the history of the development of a device for controlling a multi-apartment intercom using the Zigbee protocol.
Once upon a time I had an automatic doorphone opener based on: ESP8266, a module for two relays (16A) and a transistor with a strapping.
All this was collected on a bunch of wires and snot made of hot melt glue and looked something like the second photo.
During the New Year holidays, we got around to finishing and posting on GitHub the code that allows you to raise your TCP server for OKO devices with state transfer and the ability to control via MQTT. 💡
The MQTT AutoDiscovery mechanism has been implemented, which allows you to automatically add all devices / inputs / outputs / sensors to HomeAssistant. Supports work simultaneously with multiple devices, multithreading.
Currently, support for expansion cards and radio sockets is limited.
Ubuntu Xenial Docker image with CUPS and additional Epson TM-T20II drivers It is intended to be used as an AirPrint relay on the Synology NAS, and the local Avahi will be used to advertise printers on the network.
Changes in comparison with the original:
updated version of Ubuntu added prebuilt rastertozj from here added tm-t20-orig.ppd is tm-t20ii-rastertotmt.ppd provided on Epson site modifited to use rastertozj filter added tm-t20-NP.ppd to make possible print Nova Poshta Zebra Markings 100x100mm from iOS browser (with image scaling) added tm-t20-TG.
I need to display actual number of tickets in our service support system using big LED display. 🚨
I found LED P10 modules, they are cheap and nice, different colors available. Modules can be connected one by one to make big screen.💡
Then I need some hardware to connect to P-10 and I found VBC-P10 module from great Ukrainian 🇺🇦 manufacture VK Module. But it has only RS485 and TTL ports, while I need Ethernet so I add Ethernet - RS485 converter.
