SIGVERN RF v2.0.0-beta.3
The ESP32-S3 generation is here.
SIGVERN RF v2.0.0-beta.3 brings the proven RF gateway, Analyzer, RAW Learn & Replay, MQTT and Home Assistant feature set to ESP32-S3 N16R8. The new architecture adds dual-core task separation, 8 MB PSRAM support and significantly more processing and memory headroom.
The ESP8266 v1.2.0 edition remains available as a feature-complete legacy release. The ESP32-S3 branch is now the active SIGVERN RF platform.
v2.0.0-beta.3 highlights
The proven SIGVERN RF feature set, now on ESP32-S3.
The first public ESP32-S3 beta preserves the existing RF workflow while adding dual-core execution, PSRAM-aware buffering and substantially more hardware headroom.
ESP32-S3 Dual-Core
FreeRTOS task separation keeps RF processing apart from the main application workload for smoother concurrent operation.
8 MB PSRAM
Large non-critical RAW, Learn and Analyzer work buffers can use PSRAM while time-critical RF data remains in internal RAM.
RF Analyzer v2
The Analyzer is non-exclusive on ESP32-S3 and can run alongside RX Slots, MQTT, Home Assistant and normal gateway operation.
RAW Learn & Replay
Capture unknown RF pulse trains, preview them, save them to persistent TX slots and replay them when needed.
Universal RX Slots
Store decoded RF event identities and expose recognised events through MQTT and Home Assistant workflows.
Native Protocol Framework
Structured protocol support includes native NVKP01 Kinetic decoding and provides a foundation for additional protocols.
MQTT & Home Assistant
Configurable MQTT, event publication and Home Assistant Discovery remain integrated into the local SIGVERN RF workflow.
OTA, Backup & Restore
Update firmware from the WebUI and protect device configuration with integrated backup and restore tools.
433 / 868 MHz Selection
Two CC1101 radios support simultaneous 433.920 and 868.350 MHz operation with suitable modules and antennas.
Live System Diagnostics
The WebUI exposes CPU and memory information together with Flash, PSRAM and internal heap diagnostics.
Development roadmap
Dual-radio SIGVERN RF is available. Next comes the Deep Analyzer.
v2.0.0-beta.3 supports two CC1101 radios for simultaneous 433 and 868 MHz operation. Deep Analyzer development is planned next and has not started.
Stabilisation and refinement
Continue real-world testing and refine Analyzer responsiveness, RF behaviour and the ESP32-S3 WebUI before the first stable v2 release.
Simultaneous 433 + 868 MHz
Released in v2.0.0-beta.3: two CC1101 radios can operate together on 433 MHz and 868 MHz.
Long-range SIGVERN RF links
Planned LoRa integration will provide a foundation for direct long-range communication between future SIGVERN RF nodes.
LoRa
Distributed RF automation beyond Wi-Fi.
The concept connects local physical inputs, long-range LoRa links, RF transmitters, relay outputs and Home Assistant within one platform.
