There’s also this company, Safemonit, which offers a dashboard solution but they also claim to have a monitoring service that can meet requirements for homeowners insurance discounts.
I’m not sure how many people have signed up for their service or what the experience is like. There hasn’t been a ton of discussion in that thread since it was created a few months ago.
Personally, I would not rely on a monitored home alarm service that is dependent on smart home monitor to trigger the initial alert, regardless of the magnitude of the insurance discount.
As a cloud-dependent service without cellular backup, SmartThings is too unreliable to depend on for police, fire or ambulance dispatch in an emergency, IMHO. That’s presumably why anyone would pay money for a service like that in the first place (reliable response in case of a true emergency), the insurance discount is just a bonus.
@JDRoberts makes the very good point that the first thing you should do is find out from your insurance agent what is required to qualify for any discounts. Everything else you read or hear about discounts in this forum or elsewhere may or may not be relevant to your insurance policy.
