Hello,
Thank you for your answers, but due to my difficulties, I changed the way to install HA. I gave up the way indicated above to do it from a package as indicated here (https://community.home-assistant.io/t/hass-io-on-synology-dsm-native-package/ 125559). I installed Visual studio and saw the indentation errors. But I still have qlq problems to install some device in particular the sensors via rflink (433). I see the name “the name is 0a52080000301004d240259” in the history but I can’t find it in the configuration. In domoticz, I recover the values of my weather station via wunderground (api key and id) but here I have errors 
(Error fetching WUnderground data: ContentTypeError ("0, message = 'Attempt to decode JSON with unexpected mimetype: text / plain; charset = utf-8 ‘, url =’ http: //api.wunderground.com/api/*********************/alerts/almanac /conditions/lang:EN/q/pws:IRGIONWA31.json ")
Ok, there is a job
thank you for your patience
