Export file json with powershell : "ASCII" not UTF 16

 | ConvertTo-Json | Out-file d:\products\Dashing\json\process2.json -encoding ASCII

Send value to dashing

require 'json'


file = File.read('./process3.json')
counts = JSON.parse(file)

SCHEDULER.every '2s' do

  synergy14 = counts["poolused"]

  send_event('synergy3',   { value: synergy14} ) 

end
