sensor - hw-611 e/p 280

#1 Post by henrybcn » 30 Nov 2018, 12:57

Hi All,
I got 2 sensors hw-611 e/p 280. Seems they are an improved version of the BMP280 for temp/pressure/humidity, but I can only get it to work in ESPEASY with temp/pressure. I attach some pics. Sorry for the quality. I have been reading a lot, but did not find any way to get it work with espeasy. Anyone with a similar issue?
Rgds,
Henry

I guess they have changed some stuff in the communication. Since temp and pressure is working it seems like an easy update. Open an issue on GitHub.

Seems its a fake, just a BMP280

Make sure you have Bosch chip marking BME280 ??? U?
and NOT BMP280 Bosch chip marking ??? K?
The difference is the U or K marking.

Tks Domosapiens!
Sorry for the stupid question, but is there any way I can know if it is a K or U?

Hello,

BMP280 does only Barometric pressure while the BME280 variant does Barometric, Humidity and Temperature.

The safest way to tell which device you have is by the return values you get.
