Be the manager, not the babysitter

You can't walk every room all day

Reading gauges room by room eats the morning and still misses the spike that hit while you were in another room. LoopString puts every room on one screen.

The damage happens between checks

A check at 8, noon, and 4 gives you three data points a day. A dehumidifier that quits at 11pm won't show up until the morning walk-through — after the room has been out of range for hours.

The 3am failure with no alert

HVAC trips or CO₂ climbs in the middle of the night and nothing tells you. On-Pi alerting fires the instant a reading crosses your limit, on the channel you choose.

No record to explain a bad batch

Without the log, “why did that run underperform?” is a guess. LoopString keeps the history so you can line conditions up against the harvest and stop repeating the same drift.

Every room on one dashboard

Temperature, humidity, and CO₂ from every room in one view, with live sparklines so drift shows up at a glance instead of on the next walk-through.

Control that runs on-site

The Pi holds your setpoints and switches the relays itself, so the room keeps running to target even when the internet is down.

Out of spec, straight to your phone

SMS and in-app alerts the moment temperature, humidity, or CO₂ leaves the band. Set the windows wide enough to skip the noise and still catch the real ones.

Runs on your schedule, not a wall clock

Time-based rules drive FAE fans, misters, and lights on your grow schedule, and switch day/night targets on their own clock.
