Tuya helps you easily Design & Manufacture your own Smart Home Solutions

I was recently informed about LSC Smart Connect 3 door sensor selling on Action discounter with over 600 stores across the Netherlands, Belgium, France, Germany, Luxembourg, Austria, and Poland. The door sensor is based on ESP8266, and people have bought a few and flashed their own open source firmware converting the device into a multi-purpose sensor device with ESPNOW protocol that enables direct and low-power control of Espressif devices without the need of a router. The module inside the door sensor is called TYWE3S, which one document on the FCC website refers to as “Tuya WiFi module” and further mentions “TYWE3S is a low-power consumption module with built-in Wi-Fi solution designed by Hangzhou Tuya Technology Corporation” that is based on ESP8266 WiSoC with 1MB flash, 50 kB RAM. One person in the LetsControlIt forum thread linked above explains the stock firmware can be updated over-the-air via a Raspberry Pi 3/3+ board using a project named Tuya-Convert. That looks fun already, …

PUCK 2 Bluetooth to IR Bridge Allows you to Control Appliances from your Android or iOS Phone


We’ve already seen there are several solutions to control IR appliances such as air conditioners or (dumb) televisions via your smartphone thanks to solutions such as ZaZa Remote  that adds an IR transmitter to your 3.5mm audio jack or more recently via your USB-C port. If you don’t quite like having extra hardware connected to your smartphone WiFi to Infrared bridges such as the compact and omnidirectional Broadlink RM Mini 3 are cost-effective solutions, although you’d need one in every room where you wish to control appliances. I’ve recently noticed an even smaller “smartphone to IR” solution with PUCK v2 Bluetooth to IR bridge. The full technical details about PUCK 2 have not been made available, but we do know it’s a Bluetooth 4.2 to infrared remote bridge that transforms any iOS or Android device into a remote. The infrared LED has a range of about 4.5 meters, while Bluetooth works up to 30 meters. All you have to do …

ESP32-MeshKit is a Development Kit for ESP32 Mesh Networking


The ESP8266 was a jewel in its peak, it ruled the maker’s world in the need for creating a low-cost WiFi module. Being Arduino compatible also furthered  its glory then the ESP32 came in. ESP32 offered so much more than the ESP8266, and most importantly it was also affordable. With support for Bluetooth and WiFi, ESP32 was to open a new frontier for the development of Internet of Things applications. A major drawback of the affordable ESP32 was the lack of official support of mesh network for the chip, something that was easily possible with the ESP8266. Mesh network allows you to build a network of nodes that can communicate with each other, self heal, and many more possibilities.  But thankfully, back in 2018, Espressif Systems released the ESP Mesh Development Framework (ESP-MDF) which sits on top of the IoT Development Framework (ESP-IDF), the official development framework for the chip. The launch of the framework makes it possible to develop …
