SMA SpeedWire Integration for Home Assistant

I don't work on this integration since my inverter died, can't test changes, sorry.

Custom integration for Home Assistant to connect SMA inverters via SpeedWire protocol. The integration polls every 5 minutes only 3 entities because i only needed it for my Energy Dashboard:

• Energy production total in kWh
• Energy production today in kWh
• Power production now in kW

The integration should support a range of SMA Inverters here a list.

Installation

a) Install over HACS

• Add https://github.com/eddso/ha_sma_speedwire repository to HACS integrations
• Add SMA SpeedWire Integration integration with HACS

b) Install manual

If you don't have or don't want use HACS, install it over Terminal:

cd config/custom_components
wget https://github.com/eddso/ha_sma_speedwire/archive/refs/heads/main.tar.gz
tar --strip-components=3 -xzf main.tar.gz ha_sma_speedwire-main/custom_components/sma_speedwire

Restart

After install restart Home-Assistant under the Configuration -> System -> Restart

Setup

• After installation, you should find SMA SpeedWire under the Configuration -> Integrations -> Add integration.

• Enter IP and password (default password is '0000') of inverter on integration setup. Normaly the inverter get the IP over DHCP. So you should configure your router to give always the same IP to inverter.
