Ubidots - Node-RED flow integration

I am trying import Node-RED flow for sending data to Ubidots (https://www.bigclown.com/doc/integrations/ubidots/), but import of the flow end with error “unknow: ubidots_out” This node is a type unknown to your installation of Node-RED.

Hello, you need to install Ubidots nodes to the node-red.

They were added in the latest BigClown Playground.
