Shelly smoke is a battery powered dual sensor. It detects blockage of visible light such as is caused by smoke or water vapor and it reports temperature. It is similar in operation to the Shelly H&T with smoke rather than humidity as the companion sensor. For more details on the setup refer to the H&T at https://forums.homeseer.com/forum/li...emperature-h-t or in the mcsShelly manual.
This device does not replace smoke alarms required in buildings, but provides an easy way to get notifications through HS or other automation systems of smoke events. Battery life is advertised at two years assuming low rate of periodic reporting or manual inducement to report status. A more practical battery life should be expected to be one year with margin.
No additional configuration is needed after the device has been setup for MQTT protocol, but some option do exist as shown below. These are set from a browser with URL set to the IP of the Shelly smoke. It can be done either interactively through the HTTP server contained within the Shelly smoke or it can be done with a single URL command such as below assuming the IP of the Shelly smoke is 192.168.0.123. The red text will be changed based upon each user's specific needs.
Small temperature thresholds will result in the unit waking up more often and thereby decreasing battery life. Battery life can be improved by using a Static IP rather than Dynamics as this will reduce the time to connect to the WiFi access point.
