Re: New Smarthome Appliance Module

[nobody@xxxxxxxxxxxx (Dave Houston)]

I don't know what they use in appliance modules but they use a PIC16C622A
and a 24LC32A (4KB EEPROM) in the 2000STW lamp module. There's no reason to
think that the EEPROM would lose data from power glitches. It's more likely
to be a flaw in the firmware used in the PIC so I agree that replacing them
is probably futile until they find and fix the flaw.
