@lostOzone - I used a separate circuit with its own Utility Meter, so I know there wasn’t any other usage. What do you mean by ‘DIM counter’ ?
I’ve charged the car yesterday for 3 hours and 10 minutes at 6A (4,2 kW) = ±13,5 kWh.
the added energy reported by the Wallbox shows 13,5 kWh.

I meant the MID meter used to invoice. I’ve installed one to calculate the real loss during the charges. From the Wallbox website:
What is an MID Meter?
An MID (Measuring Instruments Directive) Meter is a certified power meter that records the energy consumption of your Wallbox charger installation with high accuracy. Complying with the MID standard, it provides precise energy readings, ensuring that you can use this data for billing or reimbursement purposes.

@Krivatri - Looks like your Wallbox is a lot more accurate than mine. When charging @ 6A, mine says 1.2kW (single phase) whereas it should say 1.4kW. It has always read significantly on the low side.
I’m not too worried about it because nobody pays me for energy used in charging my EV. It would be different if I had an employer or someone else who needed accurate invoices as @lostOzone does. Then it would make sense to install an MID meter.
Most of my energy comes from solar (especially during summer), so I can’t complain about that

do you have a power boost meter installed?
I have one installed, maybe the Wallbox gets the values from this device, but I’m not sure.
No, I don’t have a Power Boost meter installed. Maybe that’s the reason, as you say.
My Wallbox also gives a very poor measurement of the charging power. I know because I have a calibrated power meter connected to it for use in HA.
I also have a Power Boost meter connected. That however does NOT give the Wallbox a charging power/energy reading. The Power Boost meter measures the whole house current so the Wallbox can protect the main fuse. In my case that is helpful because I only have a 50A single phase mains connection. The Power Boost function is really a power limit function. The Wallbox will constrain the charging to keep the total current well below 50A. Works a charm when charging, cooking and washing f.i.

Hey there
Just noticed that my Pulsar plus is offering a new firmware version 6.7.17. Anyone know if this suffers from the same issue as 6.6.x which broke the mqtt bridge? According to the changelog it should make the compatibility better with some cars which I am interested in. I get occasional charging errors on the car after the charging is interrupted or paused which is purely cosmetic but would be nice to get rid off. I am not willing to sacrify the mqtt stuff though because of this…

Not of any help, but I have the same question.
The Wallbox (s/w 5.17.87) has not been updated for a while. Mine is rock solid, always charging when expected, not loosing WiFi connection, playing nice with HA elaborate automations (SoC limit, under-voltage protection, over-voltage protection, solar absorption).
I very much hesitate to update. Too many occasions where a s/w update ruined the experience (including my Polestar 2).
EDIT:
Now I’m confused. I use the HA Wallbox integration (@hesselonline). I assume (never assume) that is independent of the MQTT implementation (@jagheterfredrik) and hence should work with the update to 6.7.17? Can anybody confirm?

This post on the Github repo mentions version 6.7.17…
Looks like it will break the MQTT bridge

yes - the HA wallbox integration works over the cloud of Wallbox. MQTT is local.
I would not update beyond 6.4; if ever Wallbox decide to pull the plug on their cloud subscription at least you can always install the MQTT software.
Thank you. I just won’t update. If it ain’t broke, don’t fix it.
Hi There.
@hesselonline Is there a way we can use the Solar Charging enable / disable through the integration?
I found a way using python here cliviu74/wallbox: Python Module interface for Wallbox EV chargers api
but i have no idea how to rewrite or build my own integration from scratch
It can do enableEcoSmart and disableEcoSmart, which are the functions i would require

I had to hard reset my Wallbox and now I have root issues. When I send the command “python wallbox-pwn.py” the process stops at “Wallbox is processing pwnware”. At this point the wallbox should finish the process and reconnect to the wireless network but it doesn’t. I have firmware 5.0.6, I have tried various hard resets and reboots but I can’t finish the root process.
Has anyone else had the same problem? How did you solve it?
There is currently an open PR by another developer to add solar chargiging selection to the integration.

Hi,
I have a Wallbox pulsar at home but I have already a power meter from Solaredge. Actual PowerMeter is connected to a solar inverter.
I installed a RS485 modbus RTU to wifi MQTT bridge.
To do this I analyzed comunication between the two Solaredge product. Protocol is simple.
Now what I want to do is to connect Wallbox Pulsar RS485 to a other bridge Wifi MQTT to mimic EM112.
My problem is that when I power up the Wallbox Pulsar I can see it looking to find a device but the protocol seems to not be MODBUS:
Baudrate is 19200.
Frame are

Is somebody has recorded frame communication between Wallbox Pulsar on EM112?

i looked on your root access… but due to my stupidity here I’m not sure how to get to the point to enter the first command… i.e where to install bleak - in windows cmd? ssh to wallbox? on the pi? please help point me in the right direction to get started!
Secondly i have noticed the wifi on our wallbox is really bad… it wont connect to our network anymore!
I downloaded the last version from github and tested the solar integration and it works fine (and also tje rest keeps working fine…).
Looking forward to see it in an upcoming release.
You can create a utility meter helper without a reset cycle to get an ever increasing one from a periocically resetting one. But if it is to get dayly, monthly, … versions you don’t need the ever increasing one inbetween either.
Just make sure to thell the utility meter that the entity is a resetting one.
I suggest to get evcc from github cause that is a solution that is designed to work brand independently.
We have a
- family of growatt inverters
- diy battery with JK BMS
- eastron smartmeter SDM630
- pulsar plus 11 kW
And it is working once you have figured out your configuration.
Here are our 2 Pulsar Plus just plugged in
And here are our stats
