Hello,
Have you ever wish to use Blynk Apps to control unsupported IoT hardware? I have this example where my Particle Photon running ‘Twitter Torch’ and already exposing some cloud functions. But I want to control it with Blynk App. Rather than including Blynk library, I use Node JS library to run somewhere else to link between Blynk App to Photon. I could try to add Blynk library, but given how busy this Twitter Torch already, a lot of effort needed to optimize it. Well by the way this is the Node JS code, hope useful for anyone want to make a link between Blynk App and unsupported hardware using virtual pins, as long as you can find Node JS lib of that hardware.
