Connect your IoT devices via MQTT or Webhook. Set threshold rules with a safe expression engine. Get instant alerts on Telegram, Email, Slack, Teams, or Discord.
Connect any device that speaks MQTT (QoS 1) or can send HTTP webhooks. ESP32, Raspberry Pi, PLCs — all supported.
Write rules like 'temperature > 50 && humidity < 30'. No code injection risk — expressions only, no function calls.
Automatically alert when a device stops sending data. Detect offline equipment before it becomes a costly outage.
Configurable cooldown prevents notification storms. Same rule + device won't spam you every second.
'Temperature > 50 for 5 minutes' — avoid false alarms from brief spikes during normal operations like defrost cycles.
Telegram, Email, Slack, Teams, Discord — all built in. Send to multiple channels simultaneously with retry logic.
