Dorhea 4Pcs ESP8266 ESP-12F WiFi Serial Module Microcontroller 802.11N Development Board Wireless Transceiver Remote Port Network Module for NodeMCU MicroPython
The ESP-12F module combines the ESP8266 microcontroller with 4MB of flash and a PCB antenna, with 16-bit Lite mode, clocked at Supports 80 MHz and 160 MHz, supports RTOS, and integrates Wi-Fi MAC/BB/RF/PA/LNA..
The ESP-12F WiFi module supports the standard IEEE802.11 b/g/n protocol, a complete TCP/IP protocol stack. Users can use this module to add networking capabilities to existing devices or to build separate network controllers..
The default firmware can add WIFI capability to another microcontroller, but it really shines when loaded with MicroPython, or NodeMCU..
The ESP-12F is an improved version of the 12E, improve the peripheral circuit, the four laminates plate process, enhanced impedance matching, signal output is better, It is pin compatible with enhanced stability and a better antenna..
Not recommended for users who are new to the ESP8266. New users should instead look at development boards with integrated USB..

Insteon Garage Door Control & Status Kit, for Standard 2-Wire Button Controlled Garage Motors, 74551 - Insteon Hub Required for Smarthphone Control and Alerts
Remotely monitor and control (open and close) your garage door using any Insteon controller (sold separately).
Includes sensors that provide status on whether the garage door is open or closed.
Compatible with traditional 2-wire garage openers only - if your garage control button features a display panel, this kit is not compatible.
Can be used without an Insteon Hub (2245-222) - included Insteon I/O Linc module (2450) communicates over powerline only, which may cause issues if you are trying to remotely operate your garage from Insteon devices on a different electrical phase (circuit) or from an Insteon Mini Remote.
Recommend adding a Range Extender (2992-222) on the same phase to bridge the I/O Linc module with Insteon RF-only or Dual-band devices.
