I thought this was fixed a long time ago, but I get it now when trying to set up Telldus Live on 0.102.2. Does anybody have any idea what this can be? There’s nothing in the log to give me any clues.
Hi
I have the same problem 
Started with latest HA release then updated to latest beta release but it did not change anything
There is a error in the logs when trying this, I suspect it means it is on Telldus side
2019-12-25 22:37:12 ERROR (SyncWorker_10) [tellduslive] Fail
ed to retrieve authorization URL: HTTPSConnectionPool(host=’
api.telldus.com’, port=443): Max retries exceeded with url:
/oauth/requestToken (Caused by SSLError(SSLError(“bad handsh
ake: Error([(‘SSL routines’, ‘ssl_choose_client_version’, ‘u
nsupported protocol’)])”)))
I actually got it working, but only after uninstalling Hass completely and then do a full, new installation.
