PETKIT Pura Max / Pura X local control

Has anyone tried to open the litter and tried to dump the microcontroller ?
My router advertise it as Espressif, so it may be “powered” by esp or something like that.
I have a Pura MAX, but no skills at all regarding fw dump, so if anyone has the courage to reverse engineer it, I can help ! :smile:

It could be really nice to fully control the litter box in local only, instead of relying on petkit servers.
