Hi. Am I right that this development will not support the version 1 EV charger (used to connect via Enel X, or e-motorwerks) ?

I mentioned this before, and just wanted to note it here, as I'm going to be away for a while, so not likely to get to this soon, in case it helps anyone else looking at it.

Time entities are in the new 2023.6 release - https://www.home-assistant.io/blog/2023/06/07/release-20236/#new-entities-date-time-datetime - hopefully they will be able to set some sort of step so minutes can change only to 00 or 30, but I haven't looked.

As I see things there are probably 8 entities to add -

• Off Peak Weekday Start
• Off Peak Weekday End
• Off Peak Weekend Start
• Off Peak Weekend End
• Solar Start
• Solar End
• Schedule Time Start
• Schedule Time End

I had some thoughts / random notes on how the schedule could be handled (feel free to ignore all of this, I just wanted to note it somewhere in case it helps)

from datetime import time

st = time(11, 0)
et = time(16, 30)

sidx = int(st.hour * 2 + st.minute / 30)
eidx = int(et.hour * 2 + et.minute / 30)

sched = 'PPP0000000000000000000SSSSSSSSSS00000000000PPPPP00'


# Adding new schedule when start time < end time
If the string is loaded to a list it can be indexed and may be easier for manipulation

sched_list = list(sched)
sched_list.pop()  # 2 times to remove last two 0 as they aren't used
sched_list[sidx:eidx]= "S" * (eidx - sidx)
sched = "".join(sched_list)
sched = sched + "00" # need to add the 00s back on

sched
'PPP0000000000000000000SSSSSSSSSSSS000000000PPPPP00'

if sidx > eidx:  # The time period loops past midnight
sched_list[0:eidx-1] = "T" * (eidx-1)
sched_list[sidx:len(sched_list)] = "T" * (len(sched_list) - sidx)


start time from string to time object -
>>> time(sched.index("S") // 2, (sched.index("S") % 2) * 30)
datetime.time(11, 0)

end time from string to time object -
>>> time(sched.rindex("S") // 2, (sched.rindex("S") % 2) * 30)
datetime.time(15, 30)

Checking current time schedule...
sched_list[0] == sched_list[-1] # indicates the schedule loops past midnight

Still need something to read start / end time when it loops around midnight

Off peak - "P"
Scheduled Time - "T"
Solar - "S"

Things that might need to be taken in to account:

• overlapping times between entities - how should this be handled / blocked
• before adding a new time period the old one is going to need to be blanked out with 0s some how so you don't end up with an old and new block in the schedule
• The EO app on iOS at least lets you set everything before it is pushed to the server but Home Assistant does changes straight away which isn't ideal when you have linked entities like start/end time and things as above that you don't want to overlap

Should also add itertools.cycle might help with the rotating past midnight issue, and might simplify some things.

Describe the bug

EO Entities are routinely unavailable and are unreliable. On reload the entity is available but quickly becomes unavailable on button press / after short duration.

Is it possible to add an update to this plugin to know when the charger is charging Vs not charging ? Maybe something like check the charging rate?

Configuration

NA - logged in as per instructions

Describe the bug

Having used this integration for months with no issues, all entities suddenly became unavailable around 2am.
No improvements were noticed on reloading the entity, restarting HA, removing the entity and HACS integration, and reinstalling. Despite being able to log in OK via the UI, now no entities are shown. iOS EO app works fine, so presume that the problem is not with EO?

I previously had an EO Mini which was linked to the Enel X (JuiceNet) Platform. The integration exposed an "Car Charger Power" entity which gave an estimate of the point in time power the car was drawing. This allowed me to add that to the Power Flow Car Plus card as secondary information so i could see live what was being pulled but also minus the car usage from the home usage.

Looking at the EO Smart Home app it also has a "EV Charge Rate" value displayed within the app. I've put the app through a proxy to intercept the requests and observed the following:

GET //api/session/ HTTP/1.1

And the response:

HTTP/1.1 200 OK
Content-Length: 228
<headers>
X-AspNet-Version: 4.0.30319
X-Powered-By: ASP.NET


{"USID":13533350,"CPID":20356,"PiTime":1702464297,"ESTime":0,"ESCost":0,"**ESKWH":422360**,"ChargingTime":60,"PayR1":0,"PayR2":0,"PayR3":0,"PayR4":0,"ULoc":"","Location":"EO Mini","Voltage":230,"IsPaused":false,"IsOverridden":false}

I think the ESKWH value matches to the estimated power being pulled by the charger at that point in time.

I'm not sure if its possible to expose this value as an entity?

Thanks :)

Describe the solution you'd like
Is it possible to change the charging rate of the EO Mini Pro 2? I don't have the option in the app but I know the EO installers have access to this.

I’m running the latest plugin and home assistant. I’m running an Eo mini pro 3 but when I try to login it just says username /password is incorrect I have followed the guidance 10 times over have I don’t something wrong or is my model not supported thank you.
