You can then customize and install other software on the Wallbox which use a Raspberry Pi inside. There is no need to change the firmware.
I guess you can read this whole thread.

Ok,
I have read about the follwoing topic before when I purchased it many months ago spring 2023
âGain root access to Wallbox Pulsar Plus and Copper SB. This only works if you are running firmware v5.x.x. If you are running v6.x.x you can try restoring to original settings to see if your Wallbox came originally with v5.x.x from the factory. Once rooted, firmware updates shouldnât remove root access.â
To make it clear: you can root it and after that it can be used as usual but with the additional features coming along as a root users like adding software.
I knew that they had been using a raspberry pi 3 compute module something similiar from pic and that they had not been hit by supply shortages in 2021 and 2022.
I have seen the pi board when I had installed it on my own.
So it is just that I have to do the root steps at my current firmware level and then would enrich my abilities?
I will read further - thanks.
Yes, definitely!

Yep, it is confusing. The Periodically resetting option in utility meter is information about the source entity. It tells Utility meter, that if the source entityâs new value is lower than the one before, there must have been a meter reset in the source entity (a new charge cycle in this case). If that happens the new value is added to the previous total (because it is the first measurement of the new charge cycle).
The cycle is when the utility meter itself should reset. So by not setting it, it wonât ever reset and keep totalling.
So you can also use a daily total as a source to create a monthly utility meter. That what it was intended for originally I think.

yes, that is a really important piece in such cases like this to puzzle a new counter together like the cheap(er) energy measuring plugs which came with an app but without ha support and a daily resetting counter.
And only adding up those values measured in the deivce / plug once a reset must have happend is most likely far more accurate and longer than doing and relying on the math of integrations, I mean the riemann sum integral.
If your home assistant is down then for all the time of such break these counters are missing the values and will never get those back, while this kind of reverse utilitymeter is simply waiting for the next moment of a reset. If the HA server breaks down from 2 am to 9 pm then the sensors and this kind of utility meter will not loose anything till 9 pm cause at 09:01 pm the last state of the devices counters will arrive in home assistant cause those devices will have continued to count.
Those figures would only get lost if those would be reset at midnight an no HomeAssistant back before midnight.
I have bookmarked this topic to not forget.
Thanks for emphasizing again.
Hi
Can you explain how it can be fixed?
I may be dumb (surely not a developer) but following the root guide, where the code lines shall be added ? I am on a Mac
@TheMinimalist - Iâm not familiar with a Mac, but in Windows, you open a Command Prompt with Admin privileges and enter the commands shown. Itâs very easy 
Not a Mac guy either, but my guess would be in a terminal?
I finally made the root but sadly, I canât connect to the wallbox.
I figured it out the commande ssh -i id_rsa [email protected] isnât working anymore since it returns
martin@mac ~ % ssh -i id_rsa [email protected]
Unable to negotiate with 192.168.1.29 port 22: no matching host key type found. Their offer: ssh-rsa
Any idea on how to make that call work ?
Your issue is that recent versions of SSH no longer allow the use of the (now) insecure ssh-rsa encryption algorithm.
To force SSH to allow this old protocol for this host add the following line to your .ssh/config file:
Host 192.168.1.29
PubkeyAcceptedKeyTypes=+ssh-rsa
HostKeyAlgorithms=+ssh-rsa

Hi, just started using this intergration after installing my wallbox pulsar plus. I have updated to the latest firmware (6.4.9)
I did make an automation where my charger will lock after my car is either full or not at home and not pluggerd in. Unfortunately the charger automatically will unlock the charger almost straight away. I have used and admin user and for now iâm using the auto lock function but would like to manage things in HA.
Can you share your automation? In yaml?
I btw use auto lock myself and do the opposite. I unlock when the car enters the home zone and is plugged (trigger 1) or when the car is plugged and in the home zone (trigger 2)
Short note; some cars do planned heating only when their charger can provide energy. So a full car with a locked charger might not heat (or cool).
Seems to work now, I have kind of the same automation as you have, even with actionable notifications
Any idea how to get the real kWh counter and not the charging counter which does not reset if connected over midnight cause it only resets when disconnected?
I have for example days with 1,5 kWh charging session, then a break of 1 hour when I had been in the city and then another 7,3 kWh charging session which is still running since yesterday.
I can not figure out how to get a proper counter which I can use to create counters for
daily consumption
weekly consumption
monthly consumption
yearly consumption
I had the issues already last year and still have it.
I can not live with that cause I have no idea how I could get a counter that constantly increases.
thanks a lot
I found that only way to do that is to include a power meter in the charging circuit. For me the reason is that the power meter in the Wallbox seems to measure the current and assume the Voltage, that way it is often is far off reality.
I use a Shelly EM reprogrammed with ESPHome. That gives me accurate (enough) real time power measurement. That power entity can be used for the HA meter functions to give you daily, ⌠, annual consumptions.
No,
that is not true.
I can compare the HA figures in the charging sessions and if I add those up then I will get the same result which I would get from the wallbox cloud for such a month.
But I have to do that manually.
AND: those , I mean, both figures are right cause I have a counter in my circuitbreaker box somewhere which is not connected. But I have checked those figures from the Eastron SDM72 manually in the display which is an energy consumption meter but one without modbus. I have an older one just to check if the wallbox measurement are quite acurate or not. After 1500 kWh I found a difference of below 2% between both of these, the SDM 72 has been certified in 2023 with a + / - range of 3% or so.
At least in the long run of a month I have never found a difference worth to mention, but I simply want the data which are there, but hard to count due to the missing reset at midnight or an ongoing counter which is missing in the integration. I wonder cause the cloud shows all the data I need if click on monthly and cumulating.
But if I use a platform history sensor and sum the results do not make any sense.
The only way out which I do not like would be another riemann integral helper and run on top of that the counters. But that way I can not get any data from the pass even though I have such sensor or at least energy charged. And in case of maintenance no measuring by HA and therefore no sonsumption while the wallbox still is counting. I had faced this issue today and therefore I was wondering if there is really no way to get the sum of a month or week based on âaddtitional energyâ sensor. which has a really weird german translation [ âadditional energyâ instead of âenergy chargedâ ] or in german
âwallbox_pulsarplus_161183_zusatzliche_energieâ
I have no clue how to do the math to get the sum of a week from the existing additional energy sensor.
Here is an example
4 sessions and I need the sum of this sensor for a month or week and so on or I need to create an increasing counter I guess out of this.
I think it should be called âadded energyâ instead of âadditional energyâ.
thatâs how itâs called in my integration anyway.
regarding the counter, when does your added energy reset to 0, is it when your car gets plugged in or out?
