SolarManager MyStrom Bridge

A Home Assistant custom integration that bridges a virtual MyStrom Energy Control Switch to Home Assistant entities via UI config flow.

Features

• Switch entity – reflects the relay state of the virtual device; toggling the switch calls /relay?state=1|0 on the device.
• Power sensor entity – exposes the current power reading (W) returned by /report.
• Automatic polling – polls /report at a configurable interval (default: 5 s) and keeps the HA entities in sync.
• Power forwarding – optionally tracks any HA sensor entity (e.g. a real smart-plug power sensor) and forwards its value to the virtual device's POST /power endpoint every time it changes.
• Options flow – polling interval and power source entity can be changed at any time without removing the integration.

Installation via HACS

1. In HACS → Integrations → ⋮ → Custom repositories, add
   https://github.com/neuhausf/solarmanager-mystrom-bridge as Integration.
2. Install SolarManager MyStrom Bridge from HACS.
3. Restart Home Assistant.

Setup

1. Go to Settings → Devices & Services → Add Integration.
2. Search for SolarManager MyStrom Bridge.
3. Enter:
   • Name – friendly name shown in HA.
   • IP Address / Hostname – the address of the virtual MyStrom device (must be reachable from HA).
   • Polling Interval – how often to query /report (default 5 s).
4. Optionally select a Power Sensor Entity whose value (in W) will be forwarded to the device via POST /power.
