Steering wheel is clicky (mechanical clicks not speaker clicks).
Remote climate control works when I can see the car from a distance of about 50' from a window in my building. The scheduled option hasn't worked yet. That is my next thing to figure out.
Well then I have no idea what the other owner meant by "softer" steering wheel buttons, but they also mentioned that the steering wheel buttons no longer have the raised ridges on them in 2020. I can see that looking at photos, the volume control for example on the steering wheel is smooth now instead of having several raised ridges like it did in 2018 and 2019. Maybe that is what the other owner meant by "softer" although that's certainly not the word that I would have used.
There are three ways to use remote climate:
1. Key fob. Press the lock button on the fob, then within a few seconds press and hold the fan button on the fob. The flashers will flash six times to let you know that climate has started. Of course this requires close proximity to the car. It's the fastest and easiest method, I use it for example when going into a store when I expect to be inside less than thirty minutes so that AC keeps running while I am gone. Or if I have just plugged into a free charger but I want to sit in the car for a few minutes before I go inside then I start climate using the fob. Remote climate is the only way to run AC or heat while you are charging since you can't go into READY mode while charging.
2. HondaLink App - Turn On Climate. Like Start Charge and Schedule Charge, this function goes through the Honda server as an intermediary. The app on your phone communicates via standard Internet to the Honda server, you are not communicating directly to the car. Commands that you enter on the phone (like Turn on Climate) go first to the Honda server via Internet, the Honda server then "calls" the car on the AT&T 3G cellular network and passes along the command. When the car receives the "call" from Honda it turns on climate, then it lets the Honda server know this, as well as the current interior temperature, and then it "hangs up" the call. The Honda server then sends this information to your phone, again via standard Internet. If your car is out of cell phone range then the Honda server will not be able to communicate with it, in which case remote climate is not possible and you will get a message back from the Honda server letting you know that.
3. HondaLink - Schedule Climate. This one again starts initially as communication between your phone and the Honda server via standard Internet. However the Honda server does not immediately communicate the schedule to the car. Instead the Honda server waits until the scheduled time, then at the appointed time it "calls" the car and sends the command to turn on climate. At this point your phone can be completely shut off as it's now between the Honda server and the car. If for some reason the server cannot make a cell phone connection with the car at the appointed time, then climate will not run. There are other reasons remote climate might not start though, such as if the HV battery is too low, or if the climate inside the car is already within a certain range of "comfortable" temperature. Note that with remote climate you do not control the temperature, you are only able to tell it to turn on climate and then it will automatically turn on AC or heat if needed to get the car to "comfortable" temperature (whatever it is that Honda considers the range of comfortable temperature".
Sidenote - I should explain Schedule Charge since it's in this same area of how these things work. Unlike the climate schedule, which is stored on the Honda server, the charging schedule is stored in the car itself. In fact you don't even need the app to set the charge schedule you can do that inside the car from the settings menu (in the speedometer display not infotainment). However you can also use the HondaLink app to set the charge schedule, but in this case the Honda server immediately calls the car and sends the new schedule to the car (assuming the server has cellular connection with the car at that moment.). Once a charge schedule is set, it will later run even if the car is no longer in cellular range (like if you set the schedule while in one location then plug in at a different location with no cell coverage). And again your phone can be off at the scheduled start time, since the schedule is stored in the car.
The elephant in the room is the 3G network, which is in the process of being shut down. AT&T currently plans to turn off their 3G network in early 2022, meaning only about and a year and a half left. No word from Honda if our cars can be upgraded to 4G, either free or at a cost to the owner. It is hard to imagine that Honda was putting 3G into some of their cars as late as 2018, but that's because Clarity uses the old Honda infotainment system, which continues apparently into 2021 at least judging by the screenshots on the Honda website. So although it's mind boggling to think, unless Honda tells us otherwise they will be putting a 3G device into 2021 model cars. That could be one reason why HondaLink is free for Clarity, makes it easier for them to pull the plug and say "well you weren't paying for it anyway". I sure hope that's not the end result as I really use scheduled charging and remote climate a lot. All that will be left is the stupid send destination to navigation, which uses Bluetooth connection (as does odometer which is apparently why it is often behind the actual odometer). However someone claimed that if cellular network is not available the car will use WiFi to communicate with the Honda server, but I have never been able to verity that as my car is pretty much never outside of cellular coverage. Also it would be nice to hear that sometime after 2018 Honda started putting 4G into Clarity, but I have not heard even a rumor of that so far. But I hope they do that so that at least the part might be available for older Clarities (although who knows at what cost)
