The GL.iNet GL-S10 is a small IoT gateway based on an ESP32 which has the particularity of being POE powered. It’s apart from this rather unremarkable which makes it perfect for running ESPHome which is increasingly attractive due to the new bluetooth proxy feature in homeassistant. They’re also super hackable and this seems fully supported by the vendor which even gives relatively nice instructions. Aquiring such devices is pretty easy from the usual sources, I found mine on ebay for ~30eur each since I’m impatient and didn’t want to wait.
