Home power station (HKW / HPS)¶
Main device — pair this first. All other devices and widgets hang off a linked HKW.
Class: solarpanel. App device name: HKW (DE) / HPS (EN).
Live capabilities (tile)¶
| Capability | Meaning |
|---|---|
measure_power |
PV power (W) |
measure_house_consumption |
House consumption (W) |
measure_grid_delivery |
Grid power (W; sign follows E3DC convention) |
measure_battery_delivery |
Battery power (W; charge positive / discharge negative as provided by station) |
measure_battery |
Battery SoC (%) |
meter_power |
PV generation total (kWh) |
charge_time |
Remaining charge/discharge time under current conditions |
firmware_version |
Station software version |
hkw_ladeplan_active |
Whether an HKW charge plan (widget) is active |
diagnostic_report |
Text report for support (settings / flow) |
Wallbox sum power and solar share are shown on the HKW only when at least one wallbox is present (not as separate permanent capabilities on every install).
Settings (device)¶
- Connection — IP, port (usually 5033), portal credentials, RSCP password
Use Repair on the device to refresh credentials without deleting the device. - Battery — override storage size if the station reports a wrong capacity
- Diagnostics — enable detailed recording (opt-in; auto-off after ~60 minutes)
- E3DC Cloud (optional) — optional fallback for some values (local RSCP always preferred)
Incorrect battery storage size¶
Some stations report a wrong capacity. Check the battery size in Homey device settings and set the correct value manually if needed.
Important behaviours¶
Island mode / power outage¶
- Flows: Island mode started / Island mode stopped
- Conditions: island active / island possible
- Timeline messages (examples, DE): HKW unreachable, island mode, grid restored
- Detection uses station emergency-power state after reconnect; island can also be reported after the HKW comes back online if the switch happened while Homey could not poll
- Station switchover is typically ~5 s. Homey and the network path to the HKW (switch/cable/repeater) must stay up — a non-UPS Wi‑Fi repeater often causes “HKW offline” instead of a live island trigger
Charge plans vs manual EMS¶
Active plans from the HKW Ladeplaner widget take priority over manual power-mode flow commands.
Homey Energy¶
For import/export and battery energy in Homey Energy, add the Grid meter and Battery monitor devices.
