Off-grid power

If your site runs on solar or batteries, every sensor’s power budget matters. OGLAS sensors are designed to spend most of their life asleep, and only the devices that need to listen continuously stay awake.

Battery sensors

The analog node and most “report a reading every minute” sensors:

• Run on a single LiPo cell (3.7 V, 1000–2000 mAh is plenty).
• Deep-sleep between samples — current draw drops to microamps.
• Wake, read, send, wait for confirmation, sleep — the whole cycle is under a second of activity per minute.
• Survive a full season on a charge for typical reporting intervals; longer with solar trickle.

We select hardware specifically for ultra-low deep-sleep current on battery-powered sensors. Slightly higher-power variants are available for always-on devices — pick the one that suits your install.

Always-on sensors

Some devices have to listen continuously — they need to catch incoming commands the moment they arrive:

• The gate is always listening for open commands.
• The bell is always listening for trigger messages.
• The hub is always listening, full stop.

These run from mains, USB, or a 12 V rail with a battery + solar buffer. A power-management sensor paired with a smart switch has the additional trick of using your solar surplus directly — running a load on stable extra watts so the system as a whole gets more useful work out of the same panels.

Power and monitoring loop closing on itself

Here’s the elegant bit: an OGLAS analog node reading its own battery voltage and reporting it to the hub closes the loop — you can see when a sensor is going flat before it goes silent, and replace the battery before you lose readings.
