Modified send_metric function for the previous example. Replace IP/BUCKET/ORG/TOKEN placeholders with your parameters.

Code:

function send_metric(table, name, addr, value)
  if name == nil or name == '' then
    return
  end

  name = string.gsub(name, ' ', '\\ ')

  local url = 'http://IP:8086/api/v2/write?bucket=BUCKET&org=ORG'
  local body

  if type(value) == 'boolean' then
    body = string.format('%s,name=%s,addr=%s state=%s', table, name, addr, value)
  else
    -- most likely number
    body = string.format('%s,name=%s,addr=%s value=%s', table, name, addr, value)
  end

  local res, code = http.request({
    url = url,
    method = 'POST',
    body = body,
    headers = {
      Authorization = 'Token TOKEN'
    }
  })

  if code ~= 204 then
    log('error sending to influx', res, code, body)
  end
end
