Zigbee 4 relay card and sw

I bought one from Aliexpress. It came in a Tuya box. I got the model with the plastic enclosure with the 7-32V AC/DC input and 5V microUSB input.
The plastic enclosure is labeled:
Model: ZG-003-RF
INPUT: AC/DC 7-32V/USB 5V

Hubitat reports the following:
model: TS0004
isMultiEP: true
manufacturer: _TZ3000_u3oupgdy

I'm running 2.3.2.131 on a C-5.
At first I paired it and just left the HE self assign driver type to "Device". Which was misidentified. That got me into an issue where it wouldn't populate the children node. Then I saw this thread
and changed it manual to "Generic Zigbee Multi-Endpoint Switch". Hitting Configure and then rebooting my C-5 hub didn't populate the individual endpoint children. What did it for me was to hold down one of the relay input buttons for 10 seconds, and then start another "Add Zigbee Device" config cycle on the C-5 without deleting the instance of the parent device already configured in software as the "Generic Zigbee Multi-Endpoint Switch" so HE would not identify it wrong again. HE recognized that it was already previously paired and gave me a "Dismiss" option. Then I got out the Zigbee pairing mode, and I finally saw HE recognize the other nodes as EP01, EP02, EP03, EP03 and something called EPF2. I have no idea what the heck EPF2 is or what it doesn't but HE thinks its a switch. If anyone has a better clue, let me know.
