NAMF-47 release

This release is based on NAMF-47rc8. Major updates:

• support for NAM DNMS
• fixed high level of check sum errors for SDS011 in english firmware
• NAM 0.4 beta (LoRaWAN support)
• NAM SDS restarter can work as alarm device (high pin when PM values over set threshold)
• InfluxDB v2 HTTP endpoint supported

Removing reset to defaults procedure

It looks like there is some problem with reset to factory defaults. When power outage happens and there is power supply flapping NAMF resets itself to default config. Will test if this caused by reset to factory defaults procedure in current setup.

Particulate Matter App (Feinstaub App) API port update

This release uses HTTPS port for Feinstaub App

Cleanup before stable release

This release removes some code used to test SDS011 & WiFi behavior on ESP8266, cleanup before stable release.

Influx DB v2 support

This release introduces compatibility with InfluxDB v2. Now there is a checkbox to inform NAMF that Influx server is in v2. Authorization is only via token. Provide v2 write endpoint (with bucket and organization name if needed) username leave empty and as password enter Influx API token with write access.

Changes in WiFi handling

With this release user can control if WiFi is being stop on measure time. Default behavior is changed compared to earlier 47rcX - WiFi is not stopped by default. This option has to be enabled in SDS011 Advanced section.

Change how LoRaWAN mode works

This release changes how to LoRaWAN mode works (OTAA data are not persisted, so after reboot new OTAA will be required before sensor start sending data again). Data to LoRaWAN is being sent on every 5th measurement. We will return to persisting LoRaWAN session data after more tests.

PM alarm fixes

This releases fixes two bugs in alarm set on PM values (with use of SDS Restarter).

LoRa and DNMS

This pre-release brings further improvements for ESP32 NAM 0.4 and working LoRaWAN sensor.

Second new feature is support for DNMS - Digital Noise Measurement Sensor. There is a kit in preparation for NAM which provides this functionality.

If your NAM has SDS hardware restarter then you can use pin 7 to raise alert if PM2.5 or PM10 exceeds some level (adjustable in advanced SDS config section). Feature was requested from users wanting to control mechanical ventilation without any additional smart home hardware/software.

NAMF ESP32

This release brings ESP32 line back to life. It is based on Heltec Wireless Stick Lite and have support for LoRaWAN (The Things Network). To get it run you need NAM 0.4 which is in beta and will be available in January. Other changes in 47rc1:

• new version naming schema (now it is NAMF-47rc1 we have dumped 2020 from version string)
• on ESP8266 NAMF will disable WiFi when getting measurement from SDS011. It resolves problem with high checksum error, but sensor is not available during 7 seconds (on default settings)
• OTA update now can work over SSL. Fully functional for ESP32 version, work in progress for ESP8266. By default it falls back to unsecured connection when failed connecting over SSL

Version was released on Jan 8th.

Binaries with 32 in name are for ESP32. Currently only English version is available.
