I'm looking to pick up some used 2477D dimmers, and I'm wondering if there is a minimum rev. number that I should be looking for? I'd hate to waste my money on an obsolete version of the hardware.

@gweempose, not sure exactly what you are looking for.  I believe all of the 2477D's were dual band.  The following link lists I2 and I2CS introductions for the device: http://www.madreporite.com/insteon/Insteon_device_list.htm

 

Beyond that, I ran some testing on my 2477D devices to determine if Smartlabs had removed the "all-on/all-off" broadcast commands.  From what I saw, devices with a FW level V.45 did NOT respond to the All-On/All-Off broadcast: https://forum.universal-devices.com/topic/41651-all-on-removed-in-what-firmware-version-of-switchlinc-dimmers/?do=findComment&comment=369748

 

Not sure if that's what you were looking for...

Thanks for the reply! I guess I was just curious if there was some point in the run where they made a signifigant change in the hardware that increased the performance and/or reliability.

The I2CS protocol increased security - Incorporated @ FW V.41/ Rev 6.9 in late 2012 (madreporite)

Removing the All-on/All-off command seems to have been incorporated @ FW V.45 / Rev 7.8 in the 2016 time frame.

Beyond that, there "may" have been power supply capacitor changes to improve durability (similar to the changes in the PLM).  I do not have information on that.  

@Brian His a good source for hardware information on many of the devices.  Hopefully he can educate us on any improvements that may have occurred.
