I have an older home. From looking at a NEMA chart, I think I have a 10-30 dryer plug. i do see a 14-50 is listed as what most EVSE use

Well the charger came in. It has a Nema 6-20 plug with an adapter for 5-15. I won’t be able to use anyone’s dryer outlet. So be it

Have you figured out which has priority? The preferred schedule and stop time in the car or the Juice Box app?

One) I would forget about using the schedule. Never have. It isn’t going to charge unless you plug it in. Only plug it in, if you want to charge. If you want to charge right away, select Charge now on the car. If you want to charge later (at night), just set the time you want the car charged by. Easy peesy, hasn’t failed me yet except for when I had the Enel-X app set up to try to mimic reality
Two) if you set the Enel-X app to try to reflect reality, you are going to make a mistake and not get the charge up to where you want. Best practice: set the Enel-X app to where your SOC is really low (even if it is at 60% in reality). I have mine set at 20. It will assume every time you start a charge that the SOC is beginning at 20. Set your end charge at 100. This should ensure your car gets the charge that you want. You may even want to set your lower limit even lower. The Enel-X app will cut off the charger if it thinks the car is at whatever end SOC that you have programmed for it. It has happened to me twice. The car will shut off the charge when it is at whatever end state SOC you want assuming the Enel-X hasn’t already cut it off because it thinks it is at the desired SOS.

I hope that is clearer than mud

Agreed. The Enel X Way app is kind of a small disaster. I set the car, itself, to charge. I set the end point, at 85% the car still charged to 86% with the Enel x Way app schedule completely turned off. The best way for me, going forward, is to just use the car itself to schedule a charge. As annoying as it is, because I want the charge to not start until after midnight. The difference between the cost, is $0.61 peak versus $0.31 after midnight. So, it matters to me. At midnight, my peak cost goes from the highest to the lowest.

If you set "Charge Later" to end right before your rates go UP (6am?) that's virtually the same as setting the Start Time - in terms of limiting or removing any charging during higher rates. Then the vehicle will start when it needs to, and hopefully you don't often need 6+ hours of charging (again, assuming your low rates are midnight-6am).

The rates are actually from midnight to 3pm daily. Pretty big window, but, luckily, I’ll only need to charge 30% ish a night once I go back to work.

I have Enel-X app set at 0 to 80% as it seems charging to 80% is recommended for most situations. Closer to 100% if going on a longer trip the next day.

Not certain why this is still a topic. I charged last night. I told the car to be completed by 6am. I went from 53% to 80% is right at 3 hours using the Honda wall charger

I still think it’s the uncertainty of when the car is going to start charging, itself. People just have to be aware of how long it’s going to take at a certain charge point, and make sure to set the charger outside of that charging window. If I want my charger to be done at 5am for work, and I set it at that, and it’s at 10% it’s probably going to take 6-7 hours to charge. If the car decides to start charging at 10pm to be done at 5am, that’s 2 hours of my electricity being at $0.63 kwhr. At midnight, the electricity off peak is only $0.31. It cost me almost $15 just from 10pm to midnight. Versus $7 for 2 hours after midnight.

You set an end time. The car will start charging whenever it needs to to end by that time. It's NOT going to start 8 hours early - if it needs 5 hours to charge, it's END TIME - 5 HOURS. I use it all the time and works flawlessly. If you need to charge after midnight (or 9pm, or whatever) just set end time at 5am and you're not going to have problems.

I guess in the scenario you mentioned if you set the start at midnight, you would interrupt the charge and go away with a lower charge than desired. And if you needed 70% of your battery to make it through the day, you would be willing to be stranded somewhere? It takes 9 hours to charge the thing from 0-100 and probably 7 from 0-80. Your car won’t start the charge at 10pm if it is going to take 5 hours to charge it. It will start at midnight. The only way it would start at 10pm is if it would take 7 hours to charge which would mean it is probably below 20% and you are charging to 100%.

And that’s the dilemma. Because my commute is 122 miles round trip from my house. There are times where I work a 16 hour shift, and by the time I drive the 61 miles home, I have 4 hours to sleep and charge, before I get back on the road, again. On those days, I’m just going to plug in and not worry about the cost. Taking the overtime, I may make $1,600 on working the second 8 hour shift, so, it’s worth it to just plugin as soon as I get home. That’s not going to be all the time, but, in 2021 it was 3x a week. If I decide I want to start doing some of that, again, I’m going to need to charge as much as I can. I was a little skeptical getting an EV, but, being able to charge while I’m sleeping, is the main reason I went ahead with it.

Looks like the software only allows you to set the charging end time, not the start end.
I was going nuts to find the start time charging so that I can set it to charge when the power company has the best rate.
On the screen: "Your vehicle will determine the best time to start charging ready so it's ready by the selected time"
Therefore the vehicle software will set the start time, not the users.
Honda should update the software to allow users to select the charging start time, not the end time.
Anyone has faced this problem?

Right there with you. I want to set a charging window. Would also love to set a charge rate. I want a charge window when my electricity is cheapest, and I want to de - rate the charger when I am producing solar to charge with and don't want to pull from the grid. both seem like simple software updates.

Glad you see it that way also. Many folks are arguing for Honda that this is what it is and has to figure backward from the end time :-(

I definitely see a use case for a charge window. Say you only have a L1 charger available, it could take several nights to charge. If you don't need it fully charged immediately why not have a window for the nightly lower rates?
