HomeSeer HS-FS100-L Z-Wave Plus Indicator Light Sensor with Built-in Temperature Sensor & Programmable Buzzer (hub Required)

I use it in the freezer with a cable connected to it for power. I have several and they all work great.

This is on my dehumidifier in a usually dark basement affixed over the blinking full light. With the unit plugged in I was initially getting many false alarms, so many that I was going to return it. I removed the device from the Z-Wave controller and re-added it. That took care of most of the false alarms. It turns out that the light sensor sees the basement lights when they turn on, even when the unit's sensitivity is set to low. This triggers a false alarm. And, yes, I made sure the sensor was firmly attached and that there were no gaps around its edges. The lights in my basement are bright so I surmise that the plastic covering the sensor is too translucent. I put black tape over the top of the sensor and the false alarms have stopped completely. I'm happy with the way the sensor works now, but having to put black tape on it to make it reliable is awful.

works well with hubitat With Smart Things, it does not work with the new application The alarm sounds like a bus reversing warning sound

I love this company and every offering they provide. They’re innovating and have top notch quality. I’ll be a customer for life!

Reports temperature as it should, but light sensor doesn't work. HomeSeer support's answer was to make a forum post on the internet because they don't know what's wrong.

Connected to Home Assistant with ZwaveJS just fine. The buzzer works but isn’t very loud. The light sensor stayed on constantly until I applied black paint to the triangular sensor body, then finally it would show off in home assistant. The sensor still activates when the room m light turns on and doesn’t always activate when the dehumidifier full indicator LED comes on. I’ll give it three stars and wouldn’t buy another one.

You must download the customer handler from HomeSeer, but once properly selected motion and temperature seem to work. I was looking primarily for a low cost temperature sensor that I could get quickly. After 1 day the HomeSeer sensor is working as expected for temperature. It did give off beeps when it sensed motion, but I have it secluded in a small cavity with no motion, so motion will no longer alert. At this point I am satisfied and would consider purchasing more of this item.

Bought this right from homeseer and would not work with a homeseer or vera...Junk....
