Billboards have started popping up about SunPass "Pro". A toll device good across multiple state.
SunPass PRO is a portable transponder that works in Florida, Georgia and everywhere E-ZPass is accepted. SunPass PRO offers drivers the convenience of paying tolls automatically from Florida to Maine and west to Illinois, allowing nonstop travel with just one toll account.
SunPass PRO is a product of SunPass, Florida's Prepaid Toll Program.

Does anyone have this and is it worth it over just a regular SunPass, which I thought a single transponder was enough?

If you don't drive outside of Florida, no reason to get the new pass. However, if you do drive in other tolled states, then it's good to have only one transmitter.
I believe before this, the NC SmartPass was the only one that worked in all "eastern" states (Florida to Illinois.) EZ-Pass didn't work in Florida and Georgia, and I think still doesn't work in Georgia.
I guess Florida didn't get the memo that Minnesota's joining EZPass come 8/2...

The information they released was correct at the time (still is, actually, per the date noted in your post)....
Incidentally, in the discussion of this issue in the "Florida" thread, somebody mentioned that Georgia apparently also plans to become E-ZPass compatible by the end of this year.
I would argue that the planned expansion of the EZPass network would be a further selling point for SunPass Pro instead of just being ignored.
If my state did not have such a great deal for use of our in-state EZP, I would certainly go with the Florida one. A single national pass , actually international including Canada, is what has always been needed.
What toll roads are in Minnesota? There is a toll bridge to Canada, but no roads.

HO/T lanes in the Minneapolis area. If you're referring to the bridge at International Falls, I don't believe that facility takes MnPass.
CFEA (Central Florida Expressway Authority) E-Pass has been E-Z Pass compatible for 3 years. FTE is just now catching up.
Going to put this here since its relevant. If you have a SunPass account, but not a SunPass Pro and use a "toll-by-plate" facility in an E-ZPass state, they will eventually bill your account if your license plate is linked to your account. A friend of mine drove across the Chesapeake Bay Bridge and later took US-301 in Delaware expecting a bill, only to see the charges appear on his SunPass account somewhat unexpectedly. He was billed the full "toll-by-plate" rate in Delaware, but Maryland charged the non-MD E-ZPass rate.

If not "Pro" they would simply read your plate and bill the regular "plate rate".
If you are driving E-ZPass roads, you want the SunPass Pro as the equipment doesn't support the ISO 6B SeGo stickers at all. Relying on plate readers will not work with most closed ticket system toll roads or the remaining plazas that still have gates on them. You'll either be charged the full length of the roadway (for closed ticket roads) and/or the non-discounted "toll-by-plate" rates. Other facilities like the Virginia HOT lanes on 95/495 require a working tag or you'll get a hefty violation notice.

They say the Pro is accepted by E-ZPass, though.

A regular SunPass cannot be read by E-ZPass equipment. That is why the SunPass Pro exists in the first place. For a SunPass user to use E-ZPass roads they are supposed to use a SunPass Pro.
Some (most?) E-ZPass roads do not have "regular plate rates", they were only designed to have tolls paid in cash or E-ZPass transponder and the license plate cameras are only used to catch violators.

I was curious that if they have the ability to read your plate and confirm its identity, then they would have the ability to see if they subscribe to "any" eToll provider.
Technically they could provide a discounted plate rate to these "foreign" subscribers that is less than the straight non-sub rate but still more than a EZ-Pass rate.
I know how these systems can interchange data very easily and very cheaply without having to have everyone resell a bunch of multi-mode transponders.
But I get it, these are government entities we are talking about.
E-ZPass roads will not send a violation if you have the vehicle plate associated with your account. This is a fallback in case your tag doesn't read. It applies to other member agencies as well as CFX charged my E-ZPass account when my SunPass tag didn't read (my E-ZPass was wrapped in foil to prevent possible double charges). I know E-ZPass will send a note to the account holder if excessive no-tag transactions start occurring as its usually a sign that the battery in the tag is failing. Even though I'm an account holder, matching up a plate to an account still costs a bit more than just having a tag read.

I imagine that we are heading closer and closer to a national toll tag system run by various private entities, some who will be (or not) carry franchises in the lower 48.
With the question of road fuel taxation still in flux as there is a movement to EV's, there will be an increasing desire to collect revenue from non-fuel based transportation.
Fact #1 is that the ability to collect data on personal movements will be just too hard to resist.
State revenue collection, law enforcement, insurance companies will all have massive interests in seeing a national toll tag system in place.
If they decide to do this, then highway fuel taxes 'technically' could be abolished because you won't need both.
As someone from Illinois, I just bought a SunPass Pro. Personally, I like the compatibility with the multiple systems. This is definitely much more comprehensive than I-Pass/EZ-Pass. Particularly, if traveling on I-75 through GA towards points North, you really need PeachPass compatibility, and honestly, I like that this allows me to use the systems here in FL, plus virtually covers the entire East Coast. Also, if traveling to some of the mid states, I can use it there too, which was also something I couldn't do with I-Pass.

That is because Florida, Georgia, and North Carolina agreed to make their systems interoperable. The EZPass is technically not, so the SunPass Pro and the non-free NC Quick Pass transponder have to be used for E-ZPass states. Georgia is actually joining E-ZPass this July (https://peachpass.com/additional-states/), but they are going to be only a few of the EZPass states as they do not have a similar transponder yet.
I assume, at some point, E-ZPass we establish a new transponder standard where people can just use the free sticker instead of a box, or at least I hope.
So, my NTTA Toll Tag works in Texas, Oklahoma, Kansas, and now most of Florida. So, I probably should skip this SunPass "Pro" in favor of EZ Pass regular just to avoid double tolling.... should I ever be able to do road trips again....

That's interesting. I knew Georgia was joining, but the details are different from when Florida and North Carolina joined. That very much looks like they're testing some new kind of readers that can accept the stickers. I wonder if E-ZPass interoperability with the rest of the country will start rolling out faster if this works and those readers spread to the other states.
I ended up buying a SunPass Pro since my old transponder died and still frequently visit Florida. I guess that having the extra utility to save a couple dollars on EZ-Pass roads is nice? My transponder came with a secondary EZ-Pass number.
It seems that the way Georgia is doing it, they don't intend to offer a hard-case transponder at all, unlike NC QuickPass or SunPass Pro. Although it is news to me that there are so many E-ZPass states whose toll equipment can read the sticker transponders. Looks like it's time to get the rest of those states changed over.

I've always wondered why some people think the boxes are better than free stickers (although I'm not sure if the trick of attaching the sticker with your own tape instead of using the sticker's adhesive, still works). Stickers don't have batteries that run out

I have three stickers on my vehicle: My Texas registration, my NTTA Toll Tag, and my carwash tag. Having had a CA-based Fastrak box in California, I do miss that confirming "beep" that the toll has been paid when I drove across the Carquinez Toll bridge.
In Illinois, at least, there is no sticker option for I-Pass. Interesting that GA is finally joining EZ-Pass, though I'm curious what state transponders it actually will work with. For me, since I'm used to already having a transponder on my windshield, it seemed to make sense to me to have the SunPass Pro. At this point, I am not aware of any plans for EZ-Pass system to work in KS, OK, and TX, unless I missed something?

I like that I don't have to use an ugly scotch tape workaround (that I've read doesn't even always work) to have the ability to move my transponder if I need to (new windshield, new car, etc.; NY doesn't have temporary registrations for rental cars, but that's a use case for states that do). Interesting that you contrast the hard cases with "free stickers", given that NY gives away the hard case transponders for free (fun fact: NY is one of, if not the only, state to both have free transponders and no monthly/annual fee for a standard account plan; that said, people who sign up online from out of state get PANYNJ tag which do have a fee, since NJ allows such).
When my previous transponder got up there in years, they simply gave me a bag to return it and mailed me a new one.

Considering the batteries on my original SunPass lasted a decade I would imagine it easily matched or outlived the typical sticker iteration. Considering I owned three cars when I lived in Florida and used another four regularly it was just easier to use a transponder.
This reason is getting less applicable as everything goes AET, but a hard case transponder can be removed if someone is borrowing your car. As an example, when I moved out of the apartment I was staying at in my internship, my Dad has a business meeting in Watervliet the next day. So he drove his pickup truck down, we loaded my stuff into it, and then we swapped vehicles so I could take my stuff home while he went to Watervliet. I took the transponder off the windshield so he could pay cash on the Thruway.
Incidentally, the my first transponder was on three different windshields before it was replaced. My Accord needed a new windshield at one point and then I got the Civic a few years later.

E-ZPass agencies have likely been acquiring multi-protocol readers for their toll plazas when doing routine equipment replacements the past few years. All the major companies in the ETC segment offer them and the IAG likely has approved them for use for reading E-ZPass tags. I would hope the "secondary" tag reader is something that is used in more then just GA. Maybe its the SeGo 6B system that FL and NC use. When every toll lane in every E-ZPass state goes multi-protocol is when you'll finally see sticker transponders.
I know the IAG has been looking into passive stickers, but dealing with tons of legacy tags and dozens of toll agencies replacing equipment... its going to take a long time. The priority would be to get the readers in place. Eventually with normal replacement cycles (due to batteries dying) a new passive tag could be phased in at that point.

Interesting info. Thanks for that. I think I prefer the switchable E-ZPass Flex I have because it's easy just to reach over and flip the switch when I'm driving (I keep it in standard mode except when I specifically want to use HOV mode). It would be considerably more of a hassle to change it using an app, especially given the need to remember to do it before heading out on the road.
Plus I see NC Quick Pass still has the bogus and unacceptable rule about requiring one transponder for every vehicle on the account. With two people in the house and four cars, only two cars are ever being driven at any one time (other than the very rare instance when one car is at the mechanic and they might be moving it around). We have no reason to want, or need, three transponders.

In Georgia, switching between HOV and non-HOV is done on a phone app, or alternatively, on the Peach Pass website, at least 15 minutes before using the lanes. I believe NC offers both the app and the hard-case switchable transponder

The boldfaced is definitely a negative compared with E-ZPass Flex. Being able to throw the switch on the spur of the moment (say, you aren't planning to go in the HO/T lanes but heavy traffic prompts you to change your mind) is a serious convenience by comparison.
Wouldn't you just set the position based on the number of people in your vehicle? If you have enough for HOV then leave HOV mode on, then you don't have to be concerned with what mode the pass is in when deciding between express or general lanes.

But I don't always have three people in my vehicle.
I meant before you start driving, at the point when you do know how many people.
But yeah, I think I agree with the overall point, that for switchable HOV mode it's better to have it on the transponder itself than having to use an app. It's just not that much of an issue in Georgia, because our express lanes don't have free HOV except for the ones on I-85 which only have it because the express lane replaces a previous HOV lane. It usually takes 15 minutes to get to those lanes in the first place. (And out-of-state passes aren't even eligible for the free HOV mode...)
I'm still somewhat surprised there hasn't been an attempt made by somebody like Tesla or Mercedes to integrate the radio communicators required for electronic tolling into the electronics of the vehicle itself and manage the billing through their new-ish payment backends.

I was actually wrong about this - Gentex are selling rear-view mirrors that include an integrated electronic tolling module. This solution uses a multi-protocol transponder similar to NationalPass that supports the 5 common hardware/software protocols in the US (TDM, SeGo, 6C, Title 21, and ATA) and uses an intermediary account to manage the billing between agencies. These transponders have been installed in Audi vehicles starting in 2019 and Mercedes vehicles starting in 2021 and are integrated with the system infotainment. According to documentation, they also appear to support configuring HOV settings directly from the car's screen. They both use the same payment backend managed by a company called Bestpass, which handles the billing details with each compatible agency (also similar to NationalPass) and charges a $20.00 annual service charge to maintain user accounts.
I thought NationalPass was an account-based solution where instead of just trying to integrate all the transponders they just relied on license plate cameras for most of it. But I guess it's more complicated than that
