Will there be an update of Pow-U with ESP32?
During the design of Pow-U, one of the major challenges was to power it from the M-bus line on the HAN-port. In this way, Pow-U does not need a separate power supply.
We would love to use ESP32 also on Pow-U, but for the time being all versions of ESP32 consume too much power to make this possible. During S1/2022 we upgraded the Pow-K to use and ESP32-S2 module. However, also the S2 consumes too much power to be used on Pow-U.
We'll keep an eye on new products from Espressif, and as soon as a suitable and compatible module hits the market we'll start working on it!
But for the time being, the answer is sadly: No.
