Does anyone know of a similar product with replaceable battery that's not bound to a 3rd party? I can come up with something myself using an Arduino and an arcade-button but I know me. I will never get around to doing it and it will never look as slick.

$12.37 shipped to the US for an ESP8266 with AA battery holder and button style case. Not much feedback though, and the words in the url don't match the product...so it's a bit of a dice roll. https://www.aliexpress.com/item/30-energy-saving-CC2541-ibeacon-module-Bluetooth-4-0-module-BLE-ibeacon-for-indoor-navigation/32753259856.html https://www.aliexpress.com/item/30-energy-saving-CC2541-ibea...

  The quality and consistency of firmware/functionality/hidden stuff on the various 8266's I have leads me to avoid them. I had a pair that phoned home to some Chinese domain and registered all via HTTP, and a quick Wireshark yielded it phoned home for commands. Not on my network... You can pick them up cheaper on ebay, as well.

    Hmm. Something that survives a firmware overwrite?

      It depends :-) Some seem to have a fall-back or fail-safe that isn't overwritten. Even with flashing known firmware, the reliability of the little guys was questionable. Random lockups and very touchy to power source.
