ESP32 Capacitive Touch Input

ESP32 Capacitive Touch Input Using “Metallic Hole Plugs” for Buttons Using Arduino

https://youtu.be/qQG8SdMgj8I As I was finalizing design decisions for an upcoming ESP32 WiFi Kit 32 based project requiring three button input, one noticeable problem was that the WiFi Kit 32 does not possess a single mechanical pushbutton, yet alone three mechanical buttons, for input. However, the WiFi Kit 32 does have plenty of capacitive touch inputs, …

Omnik Inverter Off Its Cloud and on My MQTT 1

Omnik Inverter Off It’s Cloud and on My MQTT using Arduino

I have a solar power installation using an Omnik string inverter. Omnik is a China based manufacturer of PV inverters and they make extremely efficient devices. Optionally, you can install a WiFi module to make it “connected”. I am very content with the device, with two notable exceptions. It “phones home” to a China based …
