Automate a small office without rewiring or replacing switches: install Shelly i4 Gen4 behind existing wall switches and use single/multi-click actions across up to four inputs to trigger scenes and workflows - turn lights and appliances on/off via Shelly relays, adjust HVAC based on Shelly BLU sensors, and connect to business systems through scripting, webhooks, HTTP, MQTT, or KNXnet/IP. Set up routines like an “End of day” double-press that shuts down lights and equipment, updates AC settings, and sends a usage report, plus quick maintenance alerts with a triple-press, while keeping the same familiar physical controls.
