**Summary** Viessmann binding detects partially energy meters: - Solar panels power is provided - Power from grid is NOT provided **Installation** 2 energy meter E380-CA Connected to a Vitocal 222-S as shown on this schematic ![image](https://community-openhab-org.s3.dualstack.eu-central-1.amazonaws.com/original/3X/f/f/ffa8489741371332f37285b68d42f0bd3a640343.png) The 2 energy meters are correctly comminating through the CAN bus, values are correctly reported as shown on the screen shot of the Vicare app: ![image](https://community-openhab-org.s3.dualstack.eu-central-1.amazonaws.com/original/3X/9/6/967fceec9f5e85fe00f7ffdd0fe971a1c8907abc.png) **Configuration** Software: - openHAB 5.2.3 - Viessmann Binding 5.2.3 - OS: Ubuntu 24.04 Things: - Bridge: Viessmann Gateway TCU301\_Vitocal - Viessmann Device HEMS. Channels: - viessmann:device:xxxxxxxxx:xxxxxxxxx:HEMS:ems-heating-rod-connection-point - viessmann:device:xxxxxxxxx:xxxxxxxxx:HEMS:ems-hoca-features-tariff-based-financial-optimization#active - viessmann:device:xxxxxxxxx:xxxxxxxxx:HEMS:ems-kpi#self-consumption - viessmann:device:xxxxxxxxx:xxxxxxxxx:HEMS:ems-kpi#calculation-status - viessmann:device:xxxxxxxxx:xxxxxxxxx:HEMS:ems-kpi#autarky - Viessmann Device hems-0. Channels: - viessmann:device:xxxxxxxxx:xxxxxxxxx:hems-0:photovoltaic-installed-peak-power - viessmann:device:xxxxxxxxx:xxxxxxxxx:hems-0:photovoltaic-production-current - viessmann:device:xxxxxxxxx:xxxxxxxxx:hems-0:photovoltaic-status#status **Expected behavior** As the photovoltaic production (yellow line above) is provided by viessmann:device:xxxxxxxxx:xxxxxxxxx:hems-0:photovoltaic-production-current, I would expect a **grid supply** (grey line above). Data is available since autarky is based on this value. I tried to add manually a hems-1, but no working. Anyone with the same problem and solved it ?
