MQTT Gateway Client - Last Will topic and feature.

It would be really nice if our controllers can know if the gateway disconnects.

I think this can be implemented in MyGatewayTransportMQTTClient.cpp

bool reconnectMQTT(void)
{
GATEWAY_DEBUG(PSTR("GWT:RMQ:CONNECTING...\n"));
// Attempt to connect
if (_MQTT_client.connect(MY_MQTT_CLIENT_ID, MY_MQTT_USER, MY_MQTT_PASSWORD))

Hello everyone, Firstly, I apologize for reviving such an old thread, but I find myself in a unique situation and was hoping some of you might be able to help. I hope everyone's doing well. I have a specific inquiry that I couldn't find a recent solution for. Does anyone here know of a tool to generate "fake" Dooya remote (DC90) RF codes for curtains? I've acquired a few motors without controllers and am trying to integrate them with Home Assistant and Bradlink RF remote. Specifically, I'm searching for a way to generate codes for the Up, Down, Stop, and the "Set" button functions to configure curtain limits. Any insights or guidance would be immensely appreciated. Thank you so much in advance!

Yes, this is a good idea. but not with an ethernet switch/hub, only an ethernet crossover cable. ?? https://copperhilltech.com/wt32-eth01-serial-to-ethernet-module-based-on-esp32-for-iot-applications/

I never noticed the 20 device cap. That won't do. What I am thinking of now, is to use EspHome and just dedicate a router to handle just that network - so kinda creating an IoT network without internet access and as standalone as possible. Using static IPs should make the response better too. Thanks for looking into this.

25/25 Програма ChatGPT сказала: It seems like you're exploring the use of PJON with RS485. While RS485 is natively supported in MySensors, using PJON for collision handling can offer some interesting advantages, especially in environments where communication reliability is critical. PJON's collision management may be useful in bus systems like RS485, but it's worth considering whether the added complexity is necessary.

It seems that using an Ethernet PHY (like LAN8720) with the ESP32 in a MySensors setup requires a bit of extra configuration, including initializing the PHY using the ETH.h library and disabling the default Wi-Fi initialization. Interestingly, this setup allows for dual IP addresses, with one for the Ethernet connection and another for Wi-Fi, which can be useful in certain applications.

Just for reference, as this solution was no yet mentioned: You could also use a second UART on your controller or a software serial for debuging with the following defines: #define MY_SERIALDEVICE Serial // Interface for controller connection #define MY_DEBUGDEVICE Serial1 // Interface for debug output Regards, Edi
