Shelly Wifi Switches and Sensors Frequently Asked Questions
Can I use a dimming-knob as “SW” input to Shelly devices?
No, we do not advise this. The only thing that should be connected is an ON/OFF switch or a pushbutton, between the “SW” and “L” inputs. A dimmer connected to the “SW” input would not allow dimming as the Shelly products use relays or MOSFET transistors to respectively turn ON/OFF and dim.
Which Shelly products allow dimming?
The Shelly products that allow dimming are Shelly Dimmer2 for 110-220V AC lights and RGBW2 for 12V-24V DC loads.
How Shelly battery-powered devices work?
All Shelly battery-powered devices are at all times in sleep mode. They have a secondary ultra-low-power processor that is measuring the sensors, the battery, and the buttons. In the event of a change in any of the indicators, this processor wakes up the main CPU to transmit the information over the Wi-Fi network.
Which Shelly products measure power?
The Shelly devices that support power measurement are: Shelly 1PM and Shelly Plus 1PM Shelly 2.5 Shelly Pro Series devices Shelly EM Shelly 3EM Shelly Dimmer 2 Shelly RGBW2 Shelly Plug, Shelly Plus S, Shelly Plus US Shelly Bulbs – Duo, RGBW, Vintage
How long do the batteries last in Shelly products that use them?
I have a wind sensor attached to the roller shutter. Would it work with Shelly 2.5?
Shelly 2.5 has roller shutter management and can control the shutter’s engine. Additional sensors (for example: wind sensor) would not work.

How to add Scenes in Shelly Cloud app?
The scene is divided into 2 main stages:
1) “When” – refers to conditions that must be met to activate the scene. You can add conditions depending on the type of device or time. Shelly Cloud can support many conditions that must be true to fulfill the scene. If you want to add a condition, you have to press the “AND” button.
2) “Do” – refers to the scene that should be activated given the “When” conditions appear.
For example: (When) If Shelly Motion sensor detects motion after 10PM. (Do) Shelly Dimmer will turn on the lights with 50% dimming.If the performance of a scene depends on more than one factor, you can use “OR”.
What does “condition types” mean in Scenes?
– “One time” – when the pre-set condition has been reached, the scene will be activated only one time. For the scene to be activated again, the “WHEN” condition needs to be repeated. If you additionally insert a time in the “Condition is valid” field, the scene will not start until the “WHEN” state has existed for at least this time.
– “Repeatedly” – The “WHEN” state is constantly queried every full minute. And all set “DO” actions are also queried every minute if the “WHEN” state is not changed.
– “On any change” – This condition is mainly used for monitoring temperature or power consumption. When that condition type is chosen for the value of X, it will always activate the same scene when pre-set conditions are met.
(WHEN) Shelly EM detects more than 15W, (DO) Send notification.
In this case, every time Shelly EM detects a power consumption of over 15 W ( > 15W ), a scene will be triggered and the device will send a notification to the app, hence the user.
