Apologies if this is the wrong forum but the Insteon forum mentioned communication issues.

I see the i3 dimmer is on sale up here in Canada. 

Is it the new version of the 2477D?

Are there pros and cons?

The new version is called PS01. 

It's both a relay and a dimmer, you configure which at installation, or afterwards.

To me it's s all pros:

• It appears different than prior models, more subtle, less "clicky / techy", doesn't draw attention. The light on the switch is dimmer and more subtle
• I and others have proven via testing that it is immune to ALL ONs
• Slightly smaller package, a little easier to get in the jbox
• It uses the i3 protocol and that is claimed to better... very little docs on what exactly that is and how it works

I started over a new-to-me house and only have PS01 switches and they work really well. I have some legacy micromodule dimmers and they work as expected with the PS01s

This sounds great. I may pick a few up to check them out. 

What do you mean 'immune to ALL ONs?

I3 devices do not respond to an Insteon generated ALL ON... the ALL ON issue with Insteon products, beat to death here on the forums and yet still relevant even today. 

There's a test button on iox, you can press it, and everything else turns ON but not i3 devices... they removed the code that responds to it.

Do you have an eisy or polisy?

That module is supported by their later firmware. If you are still using an ISY994i is it not supported by its latest firmware before being discontinued.

I have the EISY. 
so essentially the i3 is the new 2477D? Are they getting rid of the 2477d ?

The 2477D is not going away

I also don't think the 2477D or 2477S are not being gotten rid of.

I also seen some of the ones that where not available. Being brought back along with the improved PLM. Both USB and Serial.
