Here are some of my observations, after now having some experience with the 180702.05 firmware and new keypads.
1. The protocol document states "Each L2-DM has an “ID” number from 0..240."
Some references in the the document refer to ID 239 as being the high end of the IDs:
"Up to 239 devices can communicate on the PDMbus and are addressed by their ID# (1..239)."
"ID#2 is reserved for the Gateway, leaving ID#s 3..239 for other devices."
I assume 240 is the correct value.
2. The following decrepencies were found in the document":
In "Reply Format A:" description, the dimming curve is specified as "dimming_curve=1=exponential, 2=linear, 3=steep exponential",
while in the Set EEPROM description, "Set ramp curve (1=linear,2=log)" is specified.
In "Reply Format A:" description, the pwm-frequency is specified as "pwm_frequency=1=60Hz, 2=122Hz, 3=576Hz, 4=1kHz, 5=2kHz",
while in the Set EEPROM description, "Set PWM frequency (1,2,3)" is specified.
3.When sending "Request scene" it appears to retrieve the scene off by one.

4. Assign Scene to a button [ID,7bsss] indicates 3 digits but scenes only go up to 64. Is there a need for 3 digits?
5. When a scene is assigned to a button, it only toggles on, not off.
6. I assume all commands listed under "SET EEPROM" and "KEYPAD EEPROM" are limited write while all other commands are unlimited write.
7. Are there any plans to allow a "mode 6" mode of operation on keypad buttons assigned to zones?
