@scalz Thanks for your answer. Assembling a sensor by my own is not really what I want (or am able to achieve). So buying assembled sensor is the only option for me. Thus probably commercially available sensors will fit better, since they can use the scaling factor of assembling a huge amount of sensors. My HA is driven by cost to performance ratio, where cost also include somewhat the amount of time to invest and performance also covers things like the ease of use, appearance etc.

Interesting to hear though that those commercial sensors might be less premium regarding the part quality, battery life etc.

This sensor looks pretty promising with its capabilities, size and low power consumption. Currently the only way to get it seems to be to order PCBs and then solder everything manually, correct?

I know this has been asked before, but is there progress in ordering this assembled? I might be interested, but have to say that this will be competing with other commercially available solutions like Aquara.
