Technical description
- The firmware controls the heating relay from LoRa-received state and local safety logic.
- Safety logic defines when the relay may be enabled, when it must be disabled and how the module reacts to radio-state changes.
- The module state depends on LoRa communication and local conditions around the controlled relay.
- Automotive use requires noise resistance, stable power and careful load-enable logic.
- The key technical areas are power supply, noise, radio range and relay reliability.
