Just had a solar and battery system installed this week alongside my Ohme Home Pro. Running Intelligent Octopus Go.

The setup:

• 10 x Aiko 480W panels (4.8kWp)
• Sigenergy EC 6.0SP inverter with 18kWh battery on Time-based Control, charging from grid during off-peak
• Sigenergy HomePro SP-F gateway for whole home backup
• Ohme Home Pro managing car charging (Renault Scenic, 87kWh) via Intelligent Octopus Go
• Ohme wired through the Sigenergy HomePro gateway
• Ohme on Manual Control in Sigen app, Ohme app handling all scheduling

The problem: Ohme keeps failing to hit its 80% target overnight with "Charge unsuccessful" errors. Car starts at ~50% so needs around 20-30kWh. Grid peaks at 7-8kW early in the window then drops to near zero around 04:00 when the Sigen battery finishes - but the car is still only at 65% at that point. The data suggest the sigenergy battery is discharging to help serve the Ohme load.

I have Home Assistant with the Local Modbus integration if there's a HA solution.

Has anyone solved this? Should Max Grid Connection Current be set? Should the Ohme be on Auto rather than Manual in the Sigen app?

Love the car but the single cup holder in the centre console is baffling when there's two of us in the front and nowhere to put a second drink.

I've been looking at the 3D printed inserts on Etsy. Anyone tried these, or have a better solution?
