Read full description

Dash IoT Dashboard is a professional IoT and IIoT monitoring and control platform for connecting, visualizing and managing connected equipment and devices — from a single installation to distributed device fleets. Libraries are available for seamless integration into many IoT device technologies including Arduino, ESP32, ESP8266, Raspberry Pi, BeagleBone and other Linux devices. The drag and drop design environment allows you to create beautiful dashboards without the need to write code. With highly customizable controls (widgets) you can design your dashboard to have your own “look and feel”. With a Dash account and a subscription, you can access the Dash cloud IoT platform, which includes the Dash MQTT broker, to allow the Dash IoT Dashboard to monitor and control your devices from anywhere. The Dash cloud IoT platform also provides many benefits such as push notifications, IoT device data storage, automated device discovery, device sharing and backups. The Dash IoT app can be used without an account, but will only be able to connect to IoT devices through BLE and TCP connections. The dash protocol is open, providing transparency, continuous improvement, and so you can implement your device code any way and anywhere you wish. - Connect to electronic devices with one or more BLE, TCP and Dash MQTT connections - Dash manages seamless transition between the different connection types - Share devices with other users - Provision TCP or MQTT credentials through BLE or SoftAP and even re-provision through TCP or MQTT once they are connected - Device discovery using any connection type - Highly customizable controls (colors, style, icons etc.) - Configure the Dash IoT Dashboard layout from the connected devices - Free to use for up to five BLE and TCP connections without an account - Store device data on the Dash server - Manage groups of users within an organization
