433 MHz is not dead! Using an ESP32 board with LoRa module to talk to 433 MHz sensors – CNX Software

Posted by jpluimers on 2025/09/23

This was a cool post: [Wayback/Archive] 433 MHz is not dead! Using an ESP32 board with LoRa module to talk to 433 MHz sensors – CNX Software

433MHz LoRa Transceiver-based ESP32 board work with regular 433 MHz sensors found on the market. This gives end users a simple off-the-shelf solution for receiving these signals without having to use a soldering iron and making a circuit.

…

This opens many doors regarding 433 MHz sensor readings with one device, including weather stations, doors, PIR, TPMS, temperature, and BBQ sensors.

SMLIGHT SLZB-06 – A Zigbee 3.0 to Ethernet, USB, and WiFi adapter with PoE support – CNX Software

Posted by jpluimers on 2022/11/01

Want: [Wayback/Archive] SMLIGHT SLZB-06 – A Zigbee 3.0 to Ethernet, USB, and WiFi adapter with PoE support – CNX Software

Startup SMLIGHT has launched the SLZB-06 Zigbee 3.0 to Ethernet, USB, and WiFi adapter with PoE support that works out of the box with open-source software such as Home Assistant and Zigbee2MQTT.

The device combines Texas Instruments’ СС2652Р microcontroller for Zigbee with ESP32 for WiFi, data transfer to Ethernet or USB, and peripheral functions such as LEDs and a button.The design is complemented with Microchip LAN8720 for Ethernet.

GitHub – arendst/Sonoff-Tasmota: Provide ESP8266 based itead Sonoff with Web, MQTT and OTA firmware using Arduino IDE or PlatformIO

Posted by jpluimers on 2020/09/15

On my things to try on IoT stuff list: [WayBack] GitHub – arendst/Sonoff-Tasmota: Provide ESP8266 based itead Sonoff with Web, MQTT and OTA firmware using Arduino IDE or PlatformIO

Many Sonoff based devices are never updated, so this firmware will likely be a much more secure solution.

Since it supports MQTT, it should be far easier to integrate into home automation solutions.

Via a comment on [WayBack] +ITEAD Studio has just launched one of the cheapest WiFi smart plug, and it should work in most of the world thanks to 6 different plug types. https://… – Jeroen Wiert Pluimers – Google+

  • How safe would “cheap” be?
  • Linas Naginionis:
    Just flash with Tasmota firmware and you can do whatever you want with it.

The device was announced at
