@Dottore curious if you have the pics posted for the lifepo4 battery install
Very, very interested in this @heisenberg
It sounds too good to be true 
I’m shopping for dual scan cat flaps at this very moment. Is there any news on the progress?
Also, is it a startup or existing brand? Do they ship US or EUR?
If they are open for use with a local API they will be open for an open-source integration, right? Can we help code, do you have a repo on GitHub to help things along?
Standard zigbee catflap would be awesome.
