LGTM. Thank you

One comment, otherwise, good for me 😉

Why have you added CONF_VERIFY_SSL in this PR ?

I was about to merge a "update available sensor" PR, and now it is getting bigger.

PR should be unitary (unless changes are small, < 50 lines).
And in any case, you should not add features into a PR that already beeing reviewed, that makes the reviewing work harder.
(Sorry I also should merge yesterday)

---

Create a new branch with those changes (can be called synology_dsm/add_verify_ssl).
Checkout to this branch, reset until 3d05b25 (correct spacing) and force push.
Open a new PR with the verify_ssl addition.

Thanks

PS: that will also help you to reach your Hacktoberfest PR goal 😉

Hi @Quentame ,
I reverted changes for this PR back to 3d05b25 (correct spacing).
After the PR is reviewed and merged, I will open a new PR for adding the ssl verification.
Sorry for confusion about adding additional changes.

regards,
Michael
