Update per @fronzbot the creator of this component you can only add one sync module 
Hey Everyone I’m having an issue adding my blink account, I have two sync modules one for the house and one for the front porch but when i add the Blink component to my Configuration.yaml I’m only getting the front porch system any ideas how I can add the whole system
blink:
username: XXXXXXXX
password: XXXXXXXXX
Yeah, that has been an issue for awhile since I only have one sync module and can’t really do local testing. I’ve got a list of things to fix, but very limited free time until late October. Here’s the issue if you want to follow it: blinkpy #36
No problem appreciate what you have already done I just added the second module last night it was in my basement for a year
If you need any help testing I have 2 sync modules up ATM
Just FYI, I finally have a PR open to support multiple sync modules: https://github.com/home-assistant/home-assistant/pull/18663
Wonderful!! Thanks for your hard work
