Also, there is another option…
You could use the Rev2 boards to send/receive data to/from a computer running an MQTT broker and Node-Red. This could then link to Blynk via the Blynk plug-in for Node-Red.
The MQTT broker/Node-Red server could run an a Windows machine on your network, which could be a fairly basic spec.
This is the basis for my home automation systems (although I use a Raspberry Pi as my broker/server rather than a Windows machine). The Mosquitto MQTT broker and Node-Red are all free, as is the Blynk plug-in for Node-Red.
