Update: The HWE-P1-G1 software update changed the device MAC address. Found it in the DHCP of my router with a dynamic address. It does respond to the http://IP-Adres/api on that ip.

Changed the DHCP reservation to the new MAC address. Solved!

After the update to version 5.16 the MAC address changed again.

Since a while I cannot see anything in the Energy (Energie) dashboard. I discovered this only when I wanted to change the tariffs earlier this week. I deleted the Homewizard device in HA and added Homewizard P1 and the energy sockets after a full reboot of my HA machine. But still in Energy all my measurements are gone over the last few years. The Energy Configuration tab returns an UNKNOWN ERROR.

Was there a language change? English to Dutch??
