I am experiencing a issue where my Enphase Gateway stops reporting and updating. Rebooting the Enphase Gateway temporarily solves the issue. after a short period, cloud updates freeze again.This issue started immediately after Enphase Support enabled Modbus TCP on my Gateway. System Setup: Victron Cerbo GX / Enphase Gateway . [3-Phase Victron Powerhouse: 15kVA MultiPlus-II + 32kWh DIY Battery Setup with ESS-Green Mode - #28 by BjoernK](https://community.victronenergy.com/t/3-phase-victron-powerhouse-15kva-multiplus-ii-32kwh-diy-battery-setup-with-ess-green-mode/60748/28) Troubleshooting Already Tried: Ruled out External Pollers: Checked local network—there are no other systems polling the Enphase Gateway via Modbus TCP., only The Cerbo GX. Adjusted Modbus Client Polling Interval in Venus OS: Connected to the Cerbo GX via SSH (PuTTY) as root. Modified /opt/victronenergy/dbus-modbus-client/dbus-modbus-client.py. Found that UPDATE\_INTERVAL was initially set to 100 ms (polling 10 times per second). Increased UPDATE\_INTERVAL to 10000 ms (10 seconds) and subsequently to 20000 ms (20 seconds) to reduce load on the Enphase hardware daemon. Restarted the process / Cerbo GX to apply changes. Power-cycled Enphase Hardware: Has anyone an idea to solve this ? ---
