Release notes

For: Elvaco Edge

Elvaco Edge 1.1.1

Release date: 2026-11-05

Background: Elvaco recommends upgrading to the latest firmware version. This release improves cellular network and DM server stability and adds some new functionalities, e.g. sending the first stored meter value immediately from all meters. For mains supplied Edges, starting from firmware 1.1.1, will now always power the M-Bus. However, for battery-driven Edges, the setting is still deactivated from factory.

Parameter changes:

  • Configuration parameters

    • New parameters

      • MinVbatNwkConn: 0 (disabled)
      • MinVbatMeterStart: 0 (disabled)

    • Renamed parameters

      • LwM2MForcedQueueMode → LwM2MQueueModePolicy: QueueModePolicyBootstrap (0)

        • This is just a renaming, no change in default value

      • Changed behaviour

        • MbusAlwaysOn: configuration unchanged, but Edge using PSU will now ignore the setting and always power the M-Bus

LwM2M Object changes:

  • Added resources

    • 33918 Elvaco syslog config (v1.0 → 1.2)

      • Resource 4 added, Historical syslog readout trigger

  • Changed resources

    • 33916 Elvaco Gateway Config (v1.8 → v1.10)

      • Resource 57 changed name, LwM2M device forced queue mode → LwM2M queue mode policy

  • Removed resources. These resources were previously not implemented/used.

    • /1 LwM2M Server

      • 2 Default min period
      • 3 Default max period

NFC Interface changes:

  • NFC TLVs

    • New TLVs

      • 0x8A: LWM2M_QUEUE_MODE_POLICY
      • 0xB3: MIN_VBAT_NWK_CONN
      • 0xB4: MIN_VBAT_METER_START

Upgrading modem firmware

Important

DFOTA upgrade path

A direct DFOTA upgrade from firmware 01.202 to 01.304 is not supported. Gateways running 01.202 must first be upgraded to 01.301, then to 01.304.

Required upgrade sequence: 01.202 → 01.301 → 01.304.

  1. Identify modem FW version

  2. If on FW 01.202

    1. Upgrade to 01.301, then
    2. Upgrade to 01.304

  3. If on FW 01.301

    1. Upgrade to 01.304

Notes: Deprecation of automatic migration to cron syntax for FW 1.0.0-1.0.1.

Edge has an automatic migration of the previously used schedules based on configuration of intervals (like readout interval, report interval and transmission interval) to cron syntax. This migration takes place at first bootup after a FW upgrade. This functionality will be deprecated in future FW releases and a manual migration will be needed. The corresponding configuration items will be removed.
