SWR/PWR meter with Wi-Fi interface
I use cheap module on base ESP8266 - NodeMCU v0.9
It has internal wifi server with GPIO and ADC functions.
This is SWR and Power meter and you can watch all information in your smartphone or PC. Just need web-browser.
After turn on you need check wifi networks and find "ESP8266". Password is null.
After connecting to "ESP8266" you need open web-browser and write "http://esp8266.local"
You'll see start page
Click "Config the wifi connection" and write your wifi network SSID and password.
That's all. Now SWR/PWR meter is in your local networks.
IP address you can find on page "Config the wifi connection"
Click "SWR/PWR meter page"
After your TX is ON you'll see next page
