Automation & Control

Your reef runs itself.
Even when you’re not home.

Connect Shelly smart outlets and automate dosing, lighting, and equipment — all without leaving the app. Schedules live on the device and run 24/7 even when your phone is off.

Shelly Smart Outlets
Connect any Shelly Plug US Gen4 in minutes — no Shelly app needed. Tag it as a doser, heater, light, skimmer, or return pump and control it directly from NextUpReef.
Automated Dosing
Calibrate your pump once, set a daily mL target, pick a schedule. NextUpReef writes it directly to the outlet — doses run on time even if your internet goes down.
Schedules Run on the Device
No cloud, no server, no phone required. Your reef stays dosed and lit through power outages, router reboots, and travel.
