arnaudne 941abd98d5 feat: initial myprimal MQTT bridge service
Dynamic MySolem/MyIndygo IoT bridge with MQTT, Home Assistant
autodiscovery, and Homebridge EasyMQTT compatibility.

- Device discovery via MySolem API on startup (all modules/inputs/outputs)
- Configurable poll engine (fast/normal/slow buckets, per-input overrides)
- MQTT retained state publishing + HA autodiscovery payloads
- Unified manual command routing (linesControl vs sendManualModuleCommand)
- Runtime config via MQTT $config/set, persisted to config.json
- Expression override system (API-provided > hardcoded > passthrough)
- Minimal REST API: /health, /state, /control, /rediscover
- Docker deployment (Dockerfile + docker-compose.yml)
- 38 unit tests

Raw Blame History

LRPR — Filter Pressure Sensor (LRPR-0D6800)

Module ID: 6a17218be0b88ea3e925524f
Serial: 1D00010D68000001
MAC: C8:B9:61:0D:68:00
UUID: 1D0058B9610D680000000001000D6800
Firmware: 6.3.0 | Hardware: A | Manufacturer: 1D
Type: lr-pr
Role: Measures filter pressure — indicates filter cleanliness / pump running state


Input

Input ID Type Unit Interval
6a17218be0b88ea3e9255251 8 (pressure) bar (unit code 6) 1 min

Raw-to-bar expression: (1.5 × raw 500) / 1000

Latest readings (2026-06-04)

16:01  0.091 bar  ← pump stopped / off
16:00  0.715 bar
15:59  0.741 bar
15:58  0.730 bar
18:41  0.081 bar  ← pump off

Normal operating pressure ~0.700.75 bar. Drop to ~0.08 bar signals pump has stopped.
This sensor can be used to detect filtration start/stop and detect dirty filter (rising pressure).


Remote state

  • Battery: 94%
  • Last radio contact: 2026-06-04T20:05:14Z
  • Relay: 60ca4276ad69dac1558f7c61 (LRMB10)
  • No programs, no outputs — pure sensor

Pressure Alert Configuration

From poolPressureAlertsVariables in the input object (retrieved via mobile API):

Parameter Value Meaning
staticPressure 0.919 bar Baseline pressure at pump start
nominalPressure 1.7275 bar Expected operating pressure
maximalPressure 1.0615 bar Upper alert threshold
atmosphericPressure 1.015 bar Calibration reference
filterCloggedMargin 0.5 bar Rise above static = filter clogged alert
filterPreCloggedMargin 0.3 bar Rise above static = pre-clog warning
activeFilterCloggedAlert true Filter clog alert enabled
activeWaterLevelLowAlert true Low water level alert enabled
activeSuctionValveClosedAlert true Suction valve closed alert enabled
waterLevelLowCount 6 Ticks below threshold before alert

Notes

  • secondaryBatteryVoltage: 80 — secondary power source present
  • Unit code 6 = bar; type 8 = pressure sensor
  • Backwash reminder alerts fire every ~15 days (shared with pool notebook)
