Local i2c sensor #88

Closed nofoxgit closed 8 months ago

nofoxgit commented 8 months ago

I can see something like "SHT2x not detected" when my WT32-sc01 starts. Can we connect local i2c sensors to touch panel ?? I can't find anything about it in the docs.. I want to connect SHT31 and send the temp and hum values over mqtt to home assistant, it would be a great feature.

The FW has builtin support for a SHT20 sensor which is part of the WT32S3-86S panel (480x480). This support is always activated when a SHT20 sensor is detected on the I2C bus (all supported panels). The WT32-SC01 has the I2C bus pins broken out on the expension headers. You can connect a SHT20 to these pins and the support in FW will be enabled automatically. As a result temperature and humidity are published by the tele/ topic in intervalls of 60 seconds. You'll see the "climate" reported on the "config" screen as well. The SHT31 will probably not work.

ok, thanks! It's worth to mention this somewhere in the documentation.

Yes sorry, the docs are a little behind ...
