day-ahead optimisation fails since 0.9.0
ragg987 opened this issue · comments
Describe the bug
Getting 2 errors when I run dayahead optimisation and the published results do not update. I think this issue started after release 0.9.0. I have not made any change to Emhass config for over a week. It last ran successfully yesterday 12/05/2024.
To Reproduce
Run day-ahead optimisation. My automation call is (have obfuscated some of my sensor names):
shell_command:
dayahead_optim: "curl -i -H "Content-Type:application/json" -X POST -d '{}' http://localhost:5001/action/dayahead-optim"
publish_data: "curl -i -H "Content-Type:application/json" -X POST -d '{}' http://localhost:5001/action/publish-data"
octopusagile_optim: "curl -i -H "Content-Type:application/json" -X POST -d '{"load_cost_forecast":{{
[states('sensor.electricity_xxx_xxx_current_rate') |float(0)]
+ ( state_attr('event.octopus_energy_electricity_xxx_xxx_current_day_rates', 'rates')|selectattr('start','gt',utcnow()) | map(attribute='value_inc_vat')|list
+ state_attr('event.octopus_energy_electricity_xxx_xxx_next_day_rates', 'rates')|selectattr('start','gt',utcnow()) | map(attribute='value_inc_vat')|list ) [:48]}}}'
http://localhost:5001/action/dayahead-optim"
Expected behavior
Dayahead completes

Additional context
The other change to my system has been update of HAOS to 2024.5.2. I have tried restating EMHASS as well as rebooting hAOS, neither have been successful.
Hi @GeoDerp, any idea why is this happening.
The code is trying to look for those files at: /app/src/emhass/data/
But actually they are in: /usr/local/lib/python3.11/dist-packages/emhass/data/
A quick but ugly solution would be to add them manually by copying, for example on line 69 of Dockerfile:
COPY cec_modules.pbz2 /app/src/emhass/data/
COPY cec_inverters.pbz2 /app/src/emhass/data/
But how come that the other files are found without problem, for example: static, template, etc.
Any ideas?
This error comes from using this as the root path: self.emhass_conf['root_path']
This was changed recently. I just lost track of where do we define that root_path parameter.
I'm releasing a patched version where I'm directly using pathlib.Path(__file__).parent to build a relative path.
Thank you. Confirmed it runs now.
Great! closing...
Sorry @davidusb-geek , I will look at this when I have some free time next.
