Universal ESP32 to MQTT client
(this project is being developed using Clion IDE + PlatformIO)
it is maximum flexible and detailed customizable client for managing DIY IoT devices based on ESP 32 platforms easy to configure and install!
PCB Project
in additional for this project was developed prototype board and it is available now in the public EasyEDA access:
https://easyeda.com/deg026/esp32-120-85
You can easily order its production through jlcpcb.com, just for about 5$
MAIN FEATURES:
- stable work via WiFi connection
- start configuration via WiFi AP and web browser
- auto-switching to AP (access point) mode in the absence of unavailable requested ssid (repeating search every 5 minutes and automatic re-connect if it appears)
- immediately ready to use, does not require any changes in the program code to start, everything is configured directly through the web interface
- control and configuration via simple web interface (including relay switching commands, and read current sensors values)
- access control by authorization using configurable user / password combinations (basic HTTP AUTH)
- synchronization of all sensors values data with the MQTT server (for relays - in both way)
- automatically detecting connection lost from MQTT broker and reconnection automatically
- OTA update - easy update using firmware upload via web interface
- support for up to 10 temperature sensors connected via 1-wire, automatic search for sensors - no need to manually write addresses (a modified version of the library is used, which solved the problems of simultaneous operation of 1wire and wifi on esp32 chips)
- control up to 10 OUTPUT pins switches (for relays etc)
- control states up to 10 INPUT pins (in the settings it is possible to switch PULLUP and PULLDOWN modes)
- easy button configuration with bounce protection, allow to collect events: current status, single click, long click, double click
- reading values of up to 5 analog signals from standard analog pins
IMPORTANT INFO:
- basic WiFi AP ssid: esp32mqtt (no password)
- ESP IP in AP mode: 192.168.4.1
- basic HTTP auth: admin / admin
