Did you manage to fix that? I have been trying for 2 days and nothing. I`ll surender i guess.

INTERACT SIEMENS S7 PLC INTO HOME ASSISTANT HOMEASSISTANT (SUPPORT s300, S1200, S1500, LOGO) 

https://github.com/xtimmy86x/ha-s7plc

 VERY EFFORTLESS PROGRAMMER THAT COMES OUT INJECTABLE. WORKS STABLE.

• ⚡ Direct PLC communication over S7 protocol via pys7.
• 🧩 Multiple entity types: light, switch, button, binary_sensor, sensor, number.
• 🧮 Value multipliers: scale raw PLC values before Home Assistant sees them (e.g., convert tenths or hundredths to human-friendly units).
• 🪶 Lightweight: minimal overhead, no broker/services required.
• 🛠️ Full UI configuration: set up and manage the integration entirely from Home Assistant's UI.
• 🔍 Optional auto-discovery: the setup wizard pre-populates PLCs found on your local network while still allowing manual IP entry.
• 📄 S7 STRING support for text sensors.

• A working Home Assistant installation.
• A reachable Siemens S7 PLC (e.g., S7-1200/S7-1500/S7-300/S7-400) over ISO-on-TCP (port 102).
• Network connectivity between Home Assistant host and the PLC (no firewalls blocking 102/TCP).
• Python dependencies installed automatically from requirements.txt (notably pys7).
