Seneye Web Server Monitoring System
The Seneye Web Server Monitoring System is a compact, web-enabled sensor and alerting platform focused on easy remote monitoring and timely notifications rather than full automation, making it an economical choice for users who want reliable alerts and then to trigger an emergency heater cutoff via an external relay. It is more affordable and simpler to deploy than full controllers like Apex or ProfiLux, but lacks built-in multi-relay cutoff hardware, so it pairs well as a monitoring-first component in mixed systems.

Review Summary
"Seneye Web Server users value its affordable continuous monitoring and alert features but commonly report sensor drift, periodic recalibration or replacement needs, and a less polished web experience. Many see it as a useful budget monitoring tool rather than a premium long-term solution."
