Repeater Add-On — Configuration
Parameters like listenCron, cmodeDurSec, smodeDurSec and the filter parameters also exist in the base app-nrf91-origin firmware, but their purpose here is different: on the Repeater they control which telegrams are re-transmitted — there is no cloud upload.
General Parameters
| Description | Key | Type | Possible Values | Default |
|---|---|---|---|---|
| Listen Cron [UTC+0] | listenCron | String | Any CRON string | H H 10 * * * |
| Verbose UART Log | verbose | Bool | true or false | false |
Wireless M-Bus Reception
| Description | Key | Type | Possible Values | Default |
|---|---|---|---|---|
| C1/T1 Listen Duration [s] | cmodeDurSec | Number | seconds, 0 = disabled, max 36000 | 300 |
| S1 Listen Duration [s] | smodeDurSec | Number | seconds, 0 = disabled, max 36000 | 0 |
| Meter ID Filter | devFilter | String | e.g. 88009035,13456035 | (empty) |
| Device Type Filter | typFilter | String | e.g. 08,07 | (empty) |
| Manufacturer Filter | mFilter | String | e.g. DME,ITW,SEN | (empty) |
| CI-Field Filter | ciFilter | String | e.g. 8a,72 | (empty) |
| Receive Tune Commands | rxTune | String | e.g. axi, blank = none | (empty) |
Filters support blacklist mode by prefixing with !, e.g. mFilter=!LOB excludes Lobaro telegrams.
For details see Meter Reception Filter Configuration.
Maximum listen duration is 36,000 seconds (10 hours). Long durations drain the battery quickly.
Repeater Settings
| Description | Key | Type | Possible Values | Default |
|---|---|---|---|---|
| Repeater Filter | rFilter | String | comma-separated repeater IDs, or * (any) | * |
| Maximum Hop Count | maxHopCount | Number | 1–4 | 4 |
| Duplicate Suppression Time [s] | suppressionTime | Number | seconds | 300 |
| Install Mode Duration [s] | installModeDuration | Number | seconds after reboot | 3600 |
| Status Telegram Interval [s] | statusInterval | Number | seconds | 30 |
| RTC Chip | rtcChip | String | ds3231, rc3028, both | both |
rFilter
Either a comma-separated list of repeater IDs (only retransmit telegrams from those repeaters) or * to retransmit from any repeater.
maxHopCount
Limits how many times a telegram may be retransmitted in a chain of repeaters.
suppressionTime
Duplicate telegrams received within this window (seconds) are suppressed.
installModeDuration
After reboot the repeater runs in install mode for this duration. In install mode the green LED blinks on each received packet.
rtcChip
Selects which RTC chip on the Repeater Add-On board is used. Use both unless directed otherwise by Lobaro support.
