Therefore, there is no solution for HL2 for controlling the antenna toggle during RX and eventually other peripherals from the software front panel yet. (In my opinion, at least RX antenna toggle belongs to radio and not to external devices) Temporarily Arduino+Pi4 duet is used as a way around. Pi4 role is to manage Arduino remotely via TCP/IP.

For remote management, via LAN / WAN (remote is also another room, another floor of the same house, garden terrace, holiday cabin, etc.) as a "mediator" can so far Raspberry Pi be used. Arduino coupled via USB with Raspberry Pi and then Raspberry Pi is managed remotely via TCP/IP LAN/WAN.
*Or even only the Raspberry Pi itself can be used with the use eg. of remote GPIO if the requirements for the number of controlled relays are not too great.
* Toggle is a function when during the reception we can switch between listening on the main or receiving antenna. But, when the PTT button is pressed the only main antenna, will always be used.

Below is the script code for cooperation between Raspberry Pi and Arduino interconnected via USB.
It is built from 2 scripts:
GatewaySerial is what we need to upload after to Arduino. With this modified GatewaySerial I can communicate remotely with Arduino via RPI which is connected to the network. Local LAN and WAN/Internet.
This part of the code that differs from the original in the GatewaySerial script is marked with a different color (below include the mysensons library)
In addition, to implementing a part of RelayActuator scrip to GatewaySerial small following modifications are done

In addition, to implementing a part of RelayActuator scrip to GatewaySerial small following modifications are done
- in function presentation BINARY changed to LIGHT
- #define RELAY_PIN must be the pin number where our firs relay is connected
- #define NUMBER_OF_RELAYS amount of relays we use. (I use 8)
- #define MY_RADIO_RF24 have to be commented with //
* By the way, caution is recommended in experiments using the I2C protocol(not only) for communication RPI with Arduino. (except Arduino Due).
Remember that RPI logic is 3.3 V and Arduino 5 V (Arduino Due 3.3 V).
For small projects I sometimes use 5Volt relays together with Raspberry PI.
RPi has 5V power available at pin 2 or 4 of the GPIO header. But this voltage is only used to power the coils of the relays while the control logic is at 3.3 V. (similarly using the MCP 23008 expander.) The coil is not controlled directly from the GPIO.

That is why it is better/safer to use level converters (or at least simple Darlington transistor array) even when no pull-up resistors are connected to the open-collector outputs. (such a resistor may have your actuator or sensor).
Modified code below: * The MySensors Arduino library handles the wireless radio link and protocol
* between your home built sensors/actuators and HA controller of choice.
* The sensors forms a self healing radio network with optional repeaters. Each
* repeater and gateway builds a routing tables in EEPROM which keeps track of the
* network topology allowing messages to be routed to nodes.

* DESCRIPTION
* The ArduinoGateway prints data received from sensors on the serial link.
* The gateway accepts input on serial which will be sent out on radio network.
*
* The GW code is designed for Arduino Nano 328p / 16MHz
*
* Wire connections (OPTIONAL):
* - Inclusion button should be connected between digital pin 3 and GND
* - RX/TX/ERR leds need to be connected between +5V (anode) and digital pin 6/5/4 with resistor 270-330R in a series
*
* LEDs (OPTIONAL):
* - To use the feature, uncomment any of the MY_DEFAULT_xx_LED_PINs
* - RX (green) - blink fast on radio message received. In inclusion mode will blink fast only on presentation received
* - TX (yellow) - blink fast on radio message transmitted. In inclusion mode will blink slowly
* - ERR (red) - fast blink on error during transmission error or receive crc error
