a simple node-red Blynk node with flexible token and pins configuration
you can also check the npmjs package page.
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.
Open Node-Red and go to Node-Red user settings -> Palette -> Install tab. Search for ‘node-red-contrib-blynk-mg’. click install and wait for the installation to complete.
in the Node-red installation directory run this command:
$ npm i node-red-contrib-blynk-mg
This will download the packages from npm package manager. After that you need to stop and start Node-Red instance and refresh it's page.
Alternatively, to deploy the node from the source code directly flow these steps:
$ git clone https://github.com/mohgeis/node-red-contrib-blynk-mg.git
then go to the node-red directory
$ cd <Node-Red-Dir>
and install the package by refering to the directory where you cloned the repo:
$ npm install <.../clone-dir/node-red-contrib-blynk-mg>
After that you need to stop and start Node-Red instance and refresh it's page.
- improve the user experience and how the msg is consumed.
