About this product
The Shelly Pro 2PM is a two-channel relay in a DIN-rail housing two modules wide, designed for installation in the distribution board. Each of the two channels switches up to 16 A, while total device load reaches 25 A at a 110–240 V AC supply, covering socket groups, lighting and small motors in a Chisinau apartment or office.<br><br>The defining trait of the Pro line is electrical metering: the device meters each channel separately through its built-in AC voltmeter and ammeter, while an internal temperature sensor watches for overheating. For an integrator this means per-channel monitoring straight from the panel, with no separate meters required.<br><br>For connectivity, the Pro 2PM combines three paths: Wi-Fi 802.11 b/g/n, wired Ethernet via an RJ45 connector and Bluetooth 4.2. The wired port gives a stable link inside a metal enclosure where Wi-Fi is attenuated. MQTT, scripting, schedules and webhooks are supported. Overheating, overvoltage, overcurrent and overpower protections are built into the device.

Smart scenarios
Three typical automations we set up after the install.
- 01Morning: warm light + blinds up + climate at 22 °C
- 02Leaving: lights off, arm sensors, close the gas
- 03Evening: warm ambient + cinema scene
Where it works
Use cases
In a Chisinau apartment the two channels turn on living-room and kitchen lighting, with consumption shown separately per room.
A single Pro 2PM switches two independent lighting circuits with power metering on each.
In a private house a schedule turns the heater on at night, while consumption is tracked straight from the panel.
Channel 1 controls the water heater, channel 2 the pump; per-channel metering shows the real energy use of heating.
In an office panel the device is connected by patch cable to a switch, with no dependence on Wi-Fi quality.
Ethernet RJ45 gives a stable link where Wi-Fi is shielded by the metal enclosure of the panel.

Frequently asked questions
How many channels does the Shelly Pro 2PM have and what load does it handle?
It has 2 independent channels, each switching up to 16 A, with a total device load of up to 25 A on a single-phase 110–240 V AC supply.How many DIN modules does it occupy on the rail?
The housing measures 94×19×69 mm and takes up two standard modules on the DIN rail in the distribution board.Does the Shelly Pro 2PM have wired Ethernet?
Yes, the device has an RJ45 LAN connector in addition to Wi-Fi 802.11 b/g/n and Bluetooth 4.2, useful for a stable link inside a metal panel.Does it measure energy consumption per channel?
Yes, the device has a built-in AC voltmeter and ammeter and meters each of the two channels separately.Does the Pro 2PM work without the cloud?
Yes, it supports MQTT, local scripts, up to 20 schedules and webhooks, so it can be integrated into a local automation system without the internet.Who should install the Shelly Pro 2PM?
As a distribution-board device powered at 110–240 V AC, installation must be done by a licensed electrician, with the breaker and cable cross-section matched to the site.
