FHEM vs Google Home

FHEM is free, GPL version 2 software for automating household devices from a self-hosted Perl server. It can control lamps, shutters, heating, and other compatible equipment while recording temperature, humidity, and power events. Control is available through web or smartphone frontends, telnet, or TCP/IP. FHEM can create devices and logs when new device data arrives, write events to files or databases with regular-expression filters, notify external programs or scripts, and run timed commands. Its text, JSON, and XML interfaces work over plain TCP/IP, SSL, or HTTP. The modular system lists more than 430 modules and supports devices and services including HomeMatic, Z-Wave, EnOcean, Philips Hue, FRITZ!Dect, Alexa, HomeKit, HomeBridge, and MQTT. Media examples include major television brands, Bose, Sonos, Kodi, Plex, and Apple TV. It offers local control, energy monitoring, voice-assistant support, installation guidance, packages, containers, documentation, and a forum.

Google Home brings compatible smart devices into one app for setup, control, and home automation. The dashboard can pin favorite devices and show camera feeds, alerts, and activity from connected first- and third-party products. Compatibility includes Google and Nest devices, Matter devices, and thousands of partner products carrying the Works with Google Home badge. Automations can come from suggestions, be drafted with Gemini from text, or be built in an editor with starters, conditions, and actions. Gemini for Home supports natural spoken requests, including multiple requests in one go. On the web, users can monitor cameras and doorbells, adjust devices, run automations, and create them with a script editor. The app is available on Android and iOS, and the service has a free plan. A Matter hub is needed to manage Matter devices while away from home. Many features also require the app, Wi-Fi, and internet access; availability can vary by country and language. Premium Standard is $10/month or $100/year, and Premium Advanced is $20/month or $200/year.
