It has 167 installs sharing analytics, works locally and was last updated August 30, 2026. Marstek BLE reads the Marstek CT002 smart meter and Venus E V3 battery over local Bluetooth. It uses the Home Assistant Bluetooth stack, including Bluetooth proxies, so the devices need no Wi-Fi, IP address, UDP or cloud access for the provided readings. The meter supplies sensors for total power, power and voltage per phase, signal strength and device version. The Venus battery adds sensors such as state of charge, state of health, battery voltage, temperatures and cell voltages, all taken from one read-only battery query. The CT002 is optional, so the integration can run with the meter only, with Venus devices only, or with both. Setup runs in the UI with automatic device discovery, and a Bluetooth address can be entered by hand; polling intervals for each device type are adjustable.

No vendor cloud in between. - **From the Marketplace**: Installed through the Marketplace, formerly HACS. - **Actively maintained**: Its author released or pushed a change in the last six months. ## Setting it up Install it from the Marketplace and restart Home Assistant, then add it under Settings, Devices and services. ### Marstek BLE - **CT002 (optional)**: Optional. Detected CT002 units appear as MST-TPM\_… with their Bluetooth MAC. The MAC can be entered manually if needed. - **Venus devices**: Select one or more detected Venus devices. Each selected device can then be named individually. - **CT002 polling interval**: Only used when a CT002 is configured. Default and recommended: 5 s. Allowed: 1 to 300 s. - **Venus polling interval**: Default: 150 s. Each cycle reads all selected Venus devices sequentially. ### Venus name - **Name** ### After setup - **CT002 (optional)**: Optional. Select, change, or remove it. Without a CT002 the integration runs with the configured Venus devices only. - **CT002 polling interval**: Only used when a CT002 is configured. Default and recommended: 5 s. Allowed: 1 to 300 s. - **Venus polling interval**: Default: 150 s. One poll reads all selected Venus devices sequentially. - **Venus devices**: Select, add, or remove devices. Each selected device can then be named individually. - **Name** Texts from the code of [Cappa83/marstek-ble-ha](https://github.com/Cappa83/marstek-ble-ha). ## Entities - **Sensors**: Total power, Phase A power, Phase B power, Phase C power, Phase A voltage, Phase B voltage, Phase C voltage, BLE signal strength, Device version, SOC, State of health (SOH), Battery voltage, and 9 more ## From the README > Stabile, schnelle und vollständig lokale BLE-Integration für Marstek CT Smart Meter / CT002 und Marstek Venus E V3 in Home Assistant. > > Marstek BLE liest die unterstützten Geräte direkt über den nativen Bluetooth-Stack von Home Assistant aus.
