SwitchGuard watches the smart plugs and switches in your eWeLink and Tuya / Smart Life accounts and raises an alarm the moment something changes — a freezer plug switched off, a pump that stopped, a device that lost its connection.

• Alarm that keeps ringing until you dismiss it, even in silent mode — full screen, even on the lock screen
• "Alarm may not reach you" check: finds the phone settings that would silence your alarms and fixes them in one tap
• Smart alerts: one alert for a power outage (all devices offline together, or this phone unplugged), unusual consumption, monthly budget and a weekly report
• Telegram: if an alarm isn't dismissed in time, the people you choose get a message, in stages; check status, take over an alarm, switch devices and run scenes with commands
• Ring again if not resolved: reminders while a device stays off, on or offline
• Live updates within seconds, with automatic backup checks
• Per-device rules: alarm, notification or nothing — for on, off, offline and online
• Ignore brief disconnections, quiet hours, a different alarm sound for each device, volume and vibration
• Automations: alarm when a switch stays on too long, or when a channel's power drops while it should be running (e.g. a pump that stalls — SONOFF SPM-4Relay / DUALR3); switch devices at sunrise, sunset or by outside temperature, only on certain hours and days
• Scenes and At home / Away / Vacation mode
• Power, voltage and energy on power-metering devices; history by day, month and year with cost (single or three-rate tariff), standby consumption and PDF/CSV reports
• Switch devices on and off from the app and manage their eWeLink timers
• Home-screen widgets (status, a device's switch) and Quick Settings tile
• Full event history with CSV export, and an optional daily summary
• Encrypted backup file for moving to a new phone
• Phones, tablets and Android TV — on a TV the alarm comes up over whatever is playing
• English and Turkish, switchable in the app
• Try it first without an account: built-in demo devices simulate every feature
• No ads, no tracking, no account of ours — your data stays on your device
• Free for 1 device; a one-time Pro purchase monitors all your devices

Works with eWeLink (SONOFF) devices — needs a free eWeLink developer App ID — and with Tuya / Smart Life devices — needs a free Tuya Cloud project. The in-app guide walks you through either one.
