Hi, have just updated mine to the latest files but get no display and this error in the logs, I have reloaded older version and all is OK.

Bit of a strange one for you.

The set_boost_charge works appears to work fine, the API calls occur and the correct schedule appears in the MyEnergi app, but the schedule on the Zappi device itself does not match.

If you try an edit the slots in the app they all appear unset.
I thought it might be a problem with types but I set a slot on the app and the types are identical.

DEBUG slt <class 'int'>
DEBUG bsh <class 'int'>
DEBUG bsm <class 'int'>
DEBUG bdh <class 'int'>
DEBUG bdm <class 'int'>
DEBUG bdd <class 'str'>

I have raised a myenergi support ticket to try and get some insight.
My own api is moving into setting Zappi schedules shortly will see if I run into the same issue.

./set_boost_charge.py 
Will aim to add 10.0kWh at 7.2kW by 8am
Zappi is currently in mode Fault/Startup. (it didn't like set_mode.sh, i manually changed it back to eco+ on zappi)
Setting boost times without car connected?

Hi Ashley, are my two Harvis confusing your code? generation is not correct as the code does not add the two values for generation and AC battery. I have two solar arrays monitored by two Harvi.

Logs show this confusion, Harvi code below

I just wanted to fetch data for last month and struggled to find, that he is just taking the first 2 days in the output.

python3 get_zappi_history.py --month=08 --show-month

So i go with the arg day=31 to make clear i want all data, but that is going to an error

python3 get_zappi_history.py --month=08 --show-month --day=31
Traceback (most recent call last):
File "get_zappi_history.py", line 217, in
main()
File "get_zappi_history.py", line 108, in main
for dom in range(1, day.tm_mday + 1):
TypeError: can only concatenate str (not "int") to str

I could fix the issue by

elif show_month:
all_data = []
for dom in range(1, int(day.tm_mday) + 1):

This seems to work for everything but I have to say that I am a complete python noob.
Maybe it would be better to have --show-month always checking the max day of the month argument and giving this value as the day argument.

Hi Ashley, sorry! found another issue has Nissan done something to their login, get these errors in the log.

zp.py line 220 self.remaining_boost_time = self._glimpse(data, 'rbt')

if Eddi isnt boosting I dont get a value in rbt and thus get : Exception has occurred: KeyError 'rbt'

{'r1a': 0, 'r2a': 0, 'rbc': 0, 'tp1': 127, 'tp2': 127} When not boosting
{'r1a': 0, 'r2a': 0, 'rbc': 0, 'rbt': 1186, 'tp1': 127, 'tp2': 127} When boosting

With a recent firmware/app update it is now possible to set the zappi in 1/3/auto phase selection in ECO+ mode, would be nice when the API would support this

This line:

...appears to be wrong. I'm interested to know where the 4 in this expression came from?

I plotted some of my data from both Octopus 30 min readings and the Zappi API data, turning their joules into average kW using the above approach and the more naive one of assuming average kW is just energy divided by time:

volts = zappi_data['v1'] / 10
joules = zappi_data['imp']
kw_1 = (joules / volts * 4) / 1000
kw_2 = (joules / 60) / 1000

kw_o = octopus_data['consumption'] *2

ax = gca()
kw_1.plot(ax=ax, label='kw_1')
kw_2.plot(ax=ax, label='kw_2')
kw_o.plot(ax=ax, label='kw_o')
ax.legend()

The plot shows the naive approach lines up with the data from Octopus:

I thought I'd chuck in issue in as I couldn't find a reason for the constant 4 so wanted to ask...
