I2c Scan and Sensor Page Help - RichCNY - 02-28-2026
I'm trying to hook up an SHT30 sensor to the I2c connector and from what I'm reading the default address is 0x44 (or 0x45) but I'm not getting an readings on the monitor page when set that way (after I add it in the sensor page). Is there any way to scan the I2c bus within KCS V3 so determine the address for certain ?
Also I assume the sensor address on the sensor page its looking for the last 2 numbers of the address as 0x44 does it save correctly, its wiped out after save, but I can type 44 and save without issues ?
Thanks in advance for any assistance,
Rich

take a photo how you connect sensor with board. how you config sensor webpage.

Thanks for the reply, to be clear I did ask how to configure the webpage as it won't take a "0x44" style address so its currently empty but I had tried just 44 (as well as 45).
Thanks for any help you can provide.

Do you bought SHT30 sensor from KinCony?
can you take a photo of your SHT30 sensor?

I did not buy it from your store as I already owned the one I installed which nearly identical to your version but the only visible difference is the wiring colors. The actual sensor module looks exactly the same.
So I can rule it out what values should I be putting in the sensor config, would that be just 44 if the default address is supposed to be 0x44.

ok, can you take a photo of your sensor. default is 0x44 address. another way, you can config by esphome, esphome will auto scan i2c device show the address on LOG.
