OpenCode in Home Assistant Extremely Slow Communicating with Ollama #43117
Description
OpenCode version: 2.5.0
Operating system: Windows 11 Pro
Steps to reproduce:
Install Ollama on a Windows PC then connect to it remotely from OpenCode in theHome Assistant app. Issue any query or instruction which takes minutes to complete.
Description
I installed Ollama on a MINISFORUM Mini PC AI X1 Pro running Windows 11 and have 48GB of RAM dedicated to GPU. Queries on models up to 30B e.g. qwen3:30b take a matter of seconds when run in Ollama. The same queries in OpenCode take many minutes. This speed degradation occurs with all of the local models I've tried. I have not tried a cloud model in Ollama. I have Home Assistant running on an HA Yellow with a Raspberry Pi 5 (CM5) and 8 GB of RAM and SSD HDD. I've tried numerous configuration options none of which improved the speed. I've listed my current configuration below.
A simple instruction like "Turn on the office lamp" takes about 4 minutes.
This instruction took over 8 minutes, I lost track of time. AI suggested using a sunlight sensor instead of fixed times. I don't use fixed times there is a dawn and dusk template used. Not sure how it came up with fixed times.
