Wifi Power Strip

Software:

C++ source, HTML, Javascript & JSON communication with the web interface.

• Full MQTT: configuration, status and distribution of the schema allowing a device auto-detection in home-assistant,
• Allows to control up to 6 switches per ESP8266 module,
• Also allows controlling multiple outputs with a single switch (tuya power strips),
• Can control up to 12 switches with an additional slave module connected via the serial port,
• allows timers on each output,
• management of single-switch multi-output devices(*),
• allows to disabe the timer of an output by maintaining the action of its corresponding switch for a few seconds (only during its activation in the case of multi-outputs with single-switch - see tuya power strip),
• several configurables SSID,
• high or low value configurable on each output (allowing different interface cards),
• configuration and retrieval of the device status by html requests (JSON format) also available,
• available backup of the output states on reboot,
• firmware update via WiFi (OTA), without loss of setting (except if the version number is modified beforehand),
• can manage contact sensors (with virtual outputs),
• the html interface can be delocalized to a dedicated server,
• dedug trace available in a telnet console (only in the C beta-version),
• each object (wifi manager, pins manager, mqtt or ntp manager) is reusable for other projects...

(*): pressing, for example, the switch 3 times with less than 1 second between each press activates the third output; if the switch is held (at least 3s) on the last press, the time delay (if set on the selected output) will be canceled.

Http requests available:

http://IPAddress	WEB User Interface
http://IPAddress/status	get the device state in JSON format - also used by the html interface
http://IPAddress/status?{'JSON setting'}	set all or parts of the state setting (see above)
http://IPAddress/html	allows the recovery of the HTML code of the interface for the purpose of its delocalization on a dedicated external server.
http://IPAddress/restart	restart the device, the output states will be restored.

TODO:

• set the "Access-Control-Allow-Origin" parameter (to allow a domain name use),
• test the new serial communication with the slave,
• add the trigger setting programmed in the interface,
• finalize the setting of all the mqtt parameters in the interface (default values in setting.h),
• do the dev doc,
• ...

Hardware:

• Webmos D1 mini + wiring diagram of the interfaces (with 2N7002 or S8050):

• 

• Progammable contactors with WiFi control:

• Interface board: 1 x Wemos mini D1, 15 x 1N5819, 3 x Zeners 3.3v, 6 resistors 360 ohms, 6 x MOSFET 2N7002 SOT23 and somes connectors... for each master / slave module (via UART) of 6 inputs and 6 outputs for power interface control (and SSR relay interface or, best to turn off led lights: 5V relay module board, 6 channels).

• 

• With 3D printed case:

• Master/Slave modules:

• switchboard (5-way module for lighting control):

• Example of selector definition in Domoticz:

• Plan view ("Fixe-the-State" to inhibit the internal timer, such a 3-second press on switch):

• 

• 

• relay modules (Serial Master/Slave):

• 

• USB WiFi-relay (same code with ESP01-1m):

• 

• Hacking - same code on TUYA power strip (TYWE3S):
