There are some members using Broadlink devices, but it may require that you have an android phone (not an iPhone). And the integration is only a partial integration.
The devices on the broadlink don’t report status so although smartthings may try to keep track of state it has no way to know you manually turned off a device
Please ask any follow-up questions about Broadlink in the following thread. That’s where you will find the people who are using it.
