+
+## Function: log
+- Endpoint: /log
+- Method: POST
+- Receives log messages from the ESP board.
+- Extracts hostname, IP address, and message from the JSON payload.
+- Prints the hostname, IP address, and message.
+- Updates the status of inputs and relays based on the message.
+- Records the log in the logs table.
+- Updates the board status in the boards table.
+
+## Function: control
+- Endpoint: /control
+- Method: POST
+- Receives control commands to update the status of relays.
+- Extracts the relay status from the JSON payload.
+- Prints the new relay status.
