hello, I was going crazy trying to command on a single group at a time, without succeeding. On and OFF acted on all groups. When I noticed in the function in the library what I think is an oversight:

Code:

function sendToGroup(Group_num,body_request)
  local response = {}
  socket.http.request({
  url = "http://"..ip_add.."/api/"..user.."/groups/"..tostring(Light_num).."/action",
  method = 'PUT',
  sink = ltn12.sink.table(response),
  headers = {
  ['content-length'] = #body_request,
  ['content-type'] = 'application/json',
  },
  source = ltn12.source.string(body_request),
  })
  return response
end

I guess Light_num on url in 4 row is wrong and to be subsustite by Group_num.... am I right?
By the way, can I address a group by its name?
