- generate a refresh_token with the right scope in http://dev.netatmo.com under my apps and choose for Token generator
- Copy the Refresh Token to the variable refresh_token

Now every run of the function get_token refreshed the token and saved it for further use.

Code:

-- get auth token from refresh token
refresh_token = 'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx'
function get_token()
    refresh = storage.get('netatmo_refresh_1', refresh_token)
 
  local request_body = "grant_type=refresh_token&client_id=" .. client_id .."&client_secret=" .. client_secret .. "&refresh_token=" .. refresh

  local body, code, hdrs, stat = https.request
  {
    url = request_token_url;
    method = "POST";
    headers =
    {
      ["Content-Type"] = "application/x-www-form-urlencoded";
      ["Content-Length"] = #request_body;
    };
    source = ltn12.source.string(request_body);
    sink = ltn12.sink.table(response_body);
  }

  if (code ~= 200) then
    if (netatmo_debug) then
      log("netatmo auth error: "..tostring(code)..", "..tostring(body))
    end
    return
  end

  local response_decode = json.decode(table.concat(response_body))
  local access_token = response_decode.access_token
  if response_decode.refresh_token then
        storage.set('netatmo_refresh_1', response_decode.refresh_token)
  end
  if (netatmo_debug) then
    log(response_body)
    log("netatmo token %s",access_token)
  end
  return "access_token=" .. access_token 
end
