4 durable buttons
with LED indication

On the front of the device are four durable buttons with LED indications for immediate feedback to the user. Actions can be marked with a customizable printed enclosure.

Short and long press,
or a toggle switch?

You can operate the device in two modes. The first distinguishes between the short and long press and the second works as a state switch.

Instant message sending
by wireless connection

The device runs from the mains with a backup battery and, immediately after pressing, transfers data over cellular networks (NB-IoT / LTE-M) or public/private LoRaWAN networks.

Fast deployment and
seamless integration

Use the HARDWARIO Manager iOS/Android app to set the behavior of each input and integrate its data from HARDWARIO Cloud.

Application areas

Typical use cases

You can utilize CHESTER Push as an ANDON system and thus enable your workers to instantly report production line problems.

By using the data acquired from the specific use of the device, you can track the utility of each production or assembly line.

In all the possible applications, CHESTER Push is the key for the significant reduction of the overall production downtime.
