Until now, there were two different ways of accessing Yoctopuce devices over the network: either by direct connection over a local network, or using the special HTTP callback mode which makes it possible to drive a Yoctopuce module sitting on a remote network behind a NAT filter. The HTTP callback method however had some limitations. Today, we are introducing a new connection method, named WebSocket callback, that brings all direct connection features to the callback scheme.
This week, we present the alter-ego of the Yocto-4-20mA-Rx, that is the Yocto-4-20mA-Tx. This small module enables you to control industrial actuators, as long as they have a 4-20mA input. Let's have a closer look, shall we?
Yoctopuce sensors are sold with programming libraries rather than with turnkey software for a specific use. Therefore, most of Yoctopuce users are developers. We do provide a few ready-to-use tools such as the command line interface, somewhat rustic, or the integration into third party solutions such as EmonCMS or Valarm. Today, we present a new solution of this type: an integration with InfluxDB and Grafana.
