# Bulk Device Management

A feature especially useful for large scale deployments, where there are a lot of devices of the same type in one Building, Floor, Space or Room.

This feature works on a device type bases, you can only manage devices in bulk if they are of the same type. For example you can control several Vikis at the same time, however you can send the same instructions to a Vicki and a Wireless Thermostat together, you would have to do it separately.

In order to control several devices simply mark them via the check box in the Devices table and press on the "Manage selected devices" button

This will bring a screen that is identical to the for the device if you would open up just one. You can change anything that you would normally be able to if it were just one device.

A very useful feature in our opinion is the ability to request an update on the current Hardware and Firmware version of the devices and send custom commands in bulk.

You can keep track of how up to date your fleet is and avoid typing commands manually for a large number of devices.

For example if you want a full report of your fleet's parameters you can send a bulk Downlink with the following command:
