About
Ortsnetz-Auslastung is an integration that sends grid voltage readings from a home's PV system to the ortsnetz-auslastung.de service. It reads three phase voltage sensors, with optional grid frequency and PV forecast sensors, and submits them together with the location of the instance to the vendor's cloud API. After the first transmission, values are sent every five minutes. It adds two sensors, a grid voltage status and a battery storage recommendation, which come back in the response to each transmission. The status shows the worst phase result as normal, warning or critical, and the recommendation suggests charging on overvoltage, discharging on undervoltage, or no action. A phase whose sensor reports exactly -1 is left out of the evaluation, as long as at least one phase gives a valid voltage. Setup is done in the UI.

From the README
Diese Anleitung richtet sich an Personen, die eine Home-Assistant-Instanz betreuen. Die HACS-Integration sendet die drei Phasenspannungen L1, L2 und L3 sowie den Standort deiner Instanz an die Ortsnetz-Auslastung-API. Nach dem ersten Senden werden die Werte alle fünf Minuten übertragen.
