Shelly Pro 1PM | Wi‑Fi & LAN, 1‑Channel Smart Relay Switch with Power Metering

What buyers think

Buyer-review evidence is broadly positive around reliability of core functions, especially remote control over Wi‑Fi and Ethernet (LAN), and usability for fixed installations. Multiple buyers specifically highlight the value of choosing Pro PM models when they want built-in energy monitoring alongside control. Some reviews also mention using Shelly devices at scale, pairing them with scripting (for example, Python) and an automation host to manage multiple circuits. Overall, the pattern suggests this controller performs as an automation-capable relay and meter, while advanced alerting expectations may require extra setup verification.

How Shelly Pro 1PM fits into smart home and facility automation

The Shelly Pro 1PM is built for people who want more than simple on/off control. It’s designed to sit on a DIN rail inside an electrical enclosure and provide smart switching plus monitoring, so you can control what’s running and also track how much energy each channel uses in real time.

Because it supports both Wi‑Fi and LAN, it can be configured for whichever network setup you prefer. The unit also supports Bluetooth gateway features, which can help with local setup workflows in ecosystems that use Shelly’s mobile/app approach.

Key features that matter for buyers

Two-channel control with integrated power metering

Shelly Pro 1PM is intended as a smart relay with power metering capabilities, using integrated precision meters to monitor energy. This matters if you’re trying to predict costs, spot unusual usage, or manage appliances based on runtime rather than guesswork.

Connectivity: Wi‑Fi and LAN, plus Bluetooth gateway support

With Wi‑Fi and LAN capability, you can choose a more reliable wired network path when it’s available, or rely on Wi‑Fi where wiring is harder. Bluetooth gateway support adds another layer of connectivity for setup and integration scenarios.

Built for breaker-box installation (DIN rail)

Designed for DIN-rail mounting, it’s meant to be installed inside a breaker box workflow. That makes it appealing for homes, offices, stores, businesses, and manufacturing facilities where you want automation without adding external bulky housings.

Monitoring, scheduling, and automation scenes

The platform supports remote control and automated events via a mobile app, and it can be used to create schedules and combine actions into scenes. That’s useful for turning appliances off overnight, enforcing business-hours routines, or aligning power behavior with your broader automation setup.

Pros and cons in plain language

Pros

• Energy visibility with real-time monitoring: Integrated precision power metering supports practical cost tracking and usage monitoring.
• Flexible connectivity: Wi‑Fi plus LAN gives you options depending on your network reliability needs.
• Installation style suits fixed wiring: DIN rail mounting is aligned with breaker-box automation projects.
• Safety-oriented load protection features: The device includes temperature, overpower, and overvoltage load protection features intended to support dependable operation.

Cons

• Alerting experience may vary by setup: Review evidence includes at least one report where alerts were not available as expected, even though data could be viewed.
• Load limits still apply: Switching is rated up to 16A per channel, so large appliances or combined loads need careful planning.

Specs you should sanity-check before buying

• Mounting: DIN rail
• Power supply voltage: AC 110–240 V
• Switching current: up to 16A (per channel)
• Operating temperature range: -20 °C to 40 °C (-5 °F to 105 °F)
• Connectivity: Wi‑Fi, Bluetooth gateway support, and LAN
• Integration features: supports scripting and MQTT, plus webhooks (URL actions)

Who should buy Shelly Pro 1PM

• You want smart relay control with built-in energy metering so you can monitor usage, not just switch loads.
• You prefer breaker-box, DIN-rail installation for cleaner permanent automation.
• You need remote control and are setting up routines like schedules or app-driven scenes.
• You value connectivity flexibility, especially Wi‑Fi plus Ethernet (LAN) where reliability matters.

Who should avoid (or reconsider)

• You’re looking for a plug-and-play smart plug style device, since DIN-rail installation is a different install workflow.
• Your application regularly exceeds the 16A per channel switching rating, or you cannot verify load requirements and wiring safety.

Is Shelly Pro 1PM worth it?

Shelly Pro 1PM is worth considering if you’re building automation where monitoring energy consumption is part of the goal, not an afterthought. Buyers who scale Shelly setups or care about per-channel metering value the Pro PM approach. If your priority is only simple switching, you may find a cheaper relay-only option, but you would give up the built-in power visibility that makes this model more useful for cost forecasting and behavior-based automation.

Before you buy: double-check your load amperage, confirm your wiring approach for DIN-rail installation, and review how you plan to use notifications in your setup so expectations match what you’ll configure.
