Hi guys,

I would like to connect two SHT25 sensors, however, they do not provide the possibility to adjust their address.
How would I do that ? Found this

but I am wondering is there some sort if soft I2C available ?

You need an I2C multiplexer like TCA9548A but it's not yet supported by ESPEasy as it requires major rework on the I2C handling routines...

Sometimes the best solution is to use a separate unit.

Yes, as long as you have space for it I tend to use multiple units instead of packing one unit.

The downside is that my cheap APs are struggling with the increasing number of clients, not that the data transfer is rising but that the many clients is making the APs a tad unstable.
