Beat The Electricity Price Hike With a Shelly Pro 1PM: The Professional Single Phase Energy Monitor

With households scrambling to save money on electricity costs ahead of Eskom’s looming price hike many are turning to Solar Systems as a solution.

The concerns with Solar are mainly around cost to install and speed of installation.

The principle around saving electricity is a simple one; “If you can measure it, you can manage and control it!”

Shelly Devices offer you a very cost effective way to constantly measure your consumption and control it – on an entire premises OR single device basis – via your smartphone and WITHOUT ongoing monthly connection costs. Your device, your data, your privacy – sorted.

Take absolute control of your electricity bill with the Shelly Pro 1PM. Designed for the professional environment and high-demand South African households, this DIN-rail mountable 1-phase energy meter provides 1% billing accuracy.

In the Nelson Mandela Bay area, crossing into the “Block 3” tariff will spike your costs to R4.57 per unit (ecl. VAT). The Shelly Pro 1PM allows you to track consumption in real-time, identifying exactly which phase or appliance is pushing you toward that expensive 500kWh threshold.

The Shelly Pro 1PM is the gold standard for automating the single biggest energy consumer in your home: the geyser. Capable of switching up to 16A (3.5kW), this compact relay fits directly into your existing isolator box or DB board.

Unlike traditional mechanical timers, the Plus 1PM provides precise power measurement, allowing you to see exactly how much each shower or bath is costing you. By automating your geyser to heat during off-peak hours and utilizing “thermal mass” strategies, you can significantly reduce your monthly consumption and avoid high-tier municipal penalties.

Why Shelly Pro1 PM:

Overpower Protection: Integrated temperature and power sensors for peace of mind.
Advanced Scheduling: Create complex 7-day schedules or use “Sunrise/Sunset” logic.
Connectivity: Works via Wi-Fi and Bluetooth—no expensive hub required.
