node-red-contrib-blynk-mg

a simple node-red Blynk node with flexible token and pins configuration

you can also check the npmjs package page.

Description!

Thip node-red package allows users to pass Blynk token and pin as part of the message. For instance:

msg = {
  'token' : ['token1', 'token-2'],
  'payload' : ['value-0' , 'value-1' , 'value-2', 'value-3'],
  'pin' : [0, 1, 2, 3]
  }   

When the above message is recieved, the node will send the payload 4 messages, to the pin list, one for each pin. all messages will be sent to each token in the msg.token list.

If msg.payload is longer than msg.pin => the node will send the first payload messages until pins list is used.

list	v 1	v 2	v 3	v 4
msg.payload	pl_0	pl_1	pl_2	pl_3
msg.pin	0	1
result	send 'pl_0' to v_pin_0	send 'pl_1' to v_pin_1

if msg.pin is longer than payload => the node will send 0 for the pins that has no match in payload list.

list	v 1	v 2	v 3	v 4
msg.payload	pl_0	pl_1
msg.pin	0	1	2	3
result	send 'pl_0' to v_pin_0	send 'pl_1' to v_pin_1	send 0 to v_pin_2	send 0 to v_pin_3

If a token is added to the node config view, this token will be appended to the msg.token list.
