  This clock has worked really well. Sure, it's not perfect, but it certainly does what it needs to.

  My son now has an Alexa Echo Show in his room so doesn't really require the clock anymore, but I have an idea in mind for it.

  I am currently embarking on a a bit of an experiment with homeassistant. I plan on using the ESPHome integration to use this clock as more of an environmental sensor by adding some sensors to it. It can then liaise with the homeassistant server and be used to automate some of his sockets to maintain his room temps and humidity.
