Flood sensor temperature

[pathduck 18]

Hi

My Fibaro Flood sensor is Wall mounted and powered by a power supply. It was included on the system with the powersupply and not battery as manual explains.

My problem is that the temperature sensor is showing approx 5 degrees higher than actual value. The temperature compensation setting has not been touched and is set to standard.

The temperature will change but not by much. As of this moment my flood sensor temperature sensor is showing 31.97oC and my Fibaro smoke sensor in the same room (small room) is showing 26.00C. With a sepererate temp sensor i am getting 24 degrees wich is problably closer to actual room temp.

Any ideas why this happens?

I have similar issue. Temperature of the smoke sensor is several degrees off from the temperature registered by the temp sensor connected to my door sensors and both return values several degrees still above actual room temperature. Also the measurements change around 0.5 degrees at most even if I leave the window open with sub zero degrees outside.

Even two smoke sensors placed side by side return different values.

I don't think the temperature sensors used in Fibaro hardware are reliable and they are not a substitute for proper temperature sensors but more of a gimmick.

I have three smoke sensors and 8 DS18B20 sensors connected to one door sensor and three different universal sensors. They all report very accurate readings and one of the universal sensors has 4 sensors connected and they are normally very accurate as well as within 0.06 degrees from each other of placed together. All sensors follow temperature variations quickly and accurately. There must be something strange going on...

Have you applied any temperature compensation parameter to the smoke sensor readings or are the parameters set to default? My sensors indicate around 27 degrees (with variations of about +- 1 degree). It's definitely not that hot in my house.

Nope, everything is right out of the box.

I got 2 flood sensors - they both agreed on temprature just after the inclusion process when placed in the same location at the same time. They are now placed where I need them and report temp typically in the range 15-25C. I believe them to be fairly accurate.

I also got 8 smoke sensors. They all agree on temp to within about 1C. (5 now mounted and typically a 1-2C temp comp (parameter 73 and 88) to take care of the temp at ceiling compared to temp at "seated" Level).

Note also sleep time/wake up interval and parameter 10 (report interval) and 12 (hysteresis). Mine are default

Mine was also accurate in the beginning, but now it is way off and i don't understand why. The temperature measurment in the smoke sensors and my door sensors seem to be pretty accurate though. I am not camplaining if it is 1 degrees diffrent because there is a lot of factors here. But the Flood sensor is way of and i don't understand why.

Same problem when plug on 12v.

I don't understand why everything is working on battery and not when using 12v adaptor?

please help

I have the same problem with mine when using external power supply. Removing the cover decreases the temperature reading so I guess that external power supply runs the unit warmer.
