Be careful with the proxy / api-key. With the proxy / api-key someone else can control your security system. So the proxy-server is a central station who can control lots of security systems and is direct a high security risk. If the server is hacked the security system can be turned off. I believe you can only trust this kind of server to a serious company. If Athom runs this kind of server the risk is less but their still be a risk. The best solution is to use SIA. With SIA the security system sends events to homey directly without any server in the middle.
if you aren’t aware of these risk don’t give someone control of you security system for an homey integration.
Stay safe an let the security system be secure!
