Hi there! I don’t think they currently have Home Assistant (HA) integration documentation available for their existing units. However, Forensics Detectors just released a new WiFi-enabled model (V001) that should have much better connectivity options for smart home integrations. The V001 features WiFi alarm notifications to your smartphone and a 7-year sensor life with a sealed Li-ion battery, so it’s designed with connectivity in mind from the ground up. The WiFi capabilities on the V001 open up many more possibilities for custom integrations and data sharing compared to their previous models. You may want to consider the new model to see if it better meets your connectivity needs. Thanks for bringing this up!
