Is to do some basic battery things. Do scaling of your data to unit you want. Have min, max values those are use to calculate nLevel. Ra ports isNormal boolean if all is OK. Location is used in otplc structure to put in in some place for you for later.

use it

To use it feed any number to it in payload. It will handle it as you set the values in parameters of the node.

return json {

• "topic" string - where to look for mqtt updates
• "volts" float - you payload as number * scale from property
• "nLevel" float - 0.0 .... 1.0 base on current volts and your min max brackets
• "isMin" boolean - if is less then min then false
• "isMax" boolean ....
• "isNormal" boolean ....
• "unit" string - from property of the "hz" float - frequency of the data

}

install it

For now installation is by entering node-red home directory then installing locally to Node-RED. So user starting node-red home director ./.node-red

npm i node-red-contrib-otplc-battery

then restart Node-RED and start your oiyshTerminal thing

example flow set

.json example to import

It's as a example node set or use link to ... ./examples/exampleNodeSet.json*
