> Email from Athom about the power supply of the Homey Pro 2023 which can cause HP23 to be slow (see screenshot below). Unsure if this applies to all batches already sent. The supplied power adapter doesn’t deliver enough power which can cause HP23’s CPU to underclock at a much lower speed. In the screenshot are instructions to find out if your HP23 underclocks as well. Athom will replace the adapter, but in the meantime you can try another power supply. Athom suggests a 15W adapter from Raspbe…
