That sounds like a great project! For RT-Thread, a common approach is to separate responsibilities into different threads—for example, one thread for sensor polling, one for UI/display updates, and another dedicated to network/MQTT communication. Using message queues or event flags between threads can help avoid blocking and keep timing predictable. Also try to keep the MQTT client in its own thread so reconnects or network delays don’t interfere with sensor timing.
For Wi-Fi modules, many developers find ESP8266 or ESP32 modules fairly easy to integrate since there are plenty of examples and AT firmware options that work well with RT-Thread. You might also find this MQTT + Home Assistant guide useful for structuring your topics and automation:

I’ve experimented with a similar setup using RTOS-based IoT devices, and one pattern that works well is structuring the system around producer–consumer threads. For instance, the temperature sensor thread can act as the producer, pushing readings into a message queue, while an MQTT thread consumes that data and publishes it to Home Assistant.
A possible layout could be:
- Sensor thread – polls the temperature every few seconds and pushes data to a queue
- Control thread – decides whether to toggle relays based on the setpoint
- Network/MQTT thread – manages Wi-Fi connectivity and publishes/subscribes to topics
- UI/display thread – updates the screen without blocking other operations
Nice setup—this kind of producer–consumer structure makes a lot of sense for keeping things responsive. Splitting tasks into separate threads like that is a clean approach, especially for MQTT and sensor handling https://www.youtube.com/watch?v=5v6zZLt-e-4/space waves
This producer-consumer paradigm makes a lot of sense for maintaining responsiveness. It's a nice setup. https://www.youtube.com/watch?v=5v6zZLt-e-4geometry dash
Hey! That's a cool project! I haven't built a thermostat specifically, but I've used RT-Thread on STM32 for similar IoT applications. For the multi-tasking, message queues are your friend - dedicate a thread to MQTT and let the others send messages when they have data.
As for Wi-Fi modules, ESP8266 is popular and well-documented, though you might need to explore RT-Thread-specific libraries. Getting all those threads synchronized is key, sometimes I feel like I'm playing Drift Hunters trying to keep everything under control! Good luck, and keep us updated on your progress!
