Barring major technical glitches, installation and configuration of a reliable locally hosted Zigbee-based solution is on the order of two hours. https://www.youtube.com/watch?v=GJEwrSSFe9s https://www.youtube.com/watch?v=GJEwrSSFe9s Here's what I used: Raspberry Pi Model 4 B Raspberry Pi CPU Raspberry Pi CPU heatsink (w/self-adhesive) Raspberry Pi manual Raspberry Pi A/C adapter Raspberry Pi case ConBee II Zigbee USB gateway USB ADATA Micro SD card reader USB cable Micro SD card (for operating system and Home Assistant) Ethernet cable (probably not needed because the Pi 4 has onboard WiFi) Thermostats: https://www.sinopetech.com/en/products/thermostat/ https://www.sinopetech.com/en/products/thermostat/ I haven't tried running a local text-to-speech engine backed by an LLM to control Home Assistant (HA). Maybe someone is working on this already? TTS: https://github.com/SYSTRAN/faster-whisper https://github.com/SYSTRAN/faster-whisper LLM: https://github.com/Mozilla-Ocho/llamafile/releases https://github.com/Mozilla-Ocho/llamafile/releases LLM: https://huggingface.co/TheBloke/Nous-Hermes-2-Mixtral-8x7B-DPO-GGUF/blob/main/nous-hermes-2-mixtral-8x7b-dpo.Q4_K_M.gguf https://huggingface.co/TheBloke/Nous-Hermes-2-Mixtral-8x7B-D... HA: https://www.home-assistant.io/ https://www.home-assistant.io/ It would take some tweaking to get the voice commands working correctly.
