Hello. How do you get the access token using hacs?

[tjorim]

Please read the documentation: https://github.com/Chouffy/home_assistant_tgtg?tab=readme-ov-file#1-get-access-tokens

"This is to be executed outside of Home Assistant, i.e. on your local machine."

[Thundervf]

I already know that. But if I'm asking it it's because I don't understand how to get it.

[tjorim]

This part has nothing to do with HACS: the only thing HACS does is downloading this custom integration to your Home Assistant installation. On your pc: install python, install the tgtg python library and run the tgtg_get_tokens script.

thank you very much for this project. it has helped me a lot. unfortunately, however, the wrong time was displayed which is probably related to the time zone. Here is the part i changed in the sensor.py:

from future import annotations
from datetime import datetime, timedelta

def update(self) -> None:
    global tgtg_client
    self.tgtg_answer = tgtg_client.get_item(item_id=self.item_id)

    # time shift 2 hours forward for pickup_start
    pickup_start_time = self.tgtg_answer.get("pickup_interval", {}).get("start")
    if pickup_start_time:
        try:
            pickup_start_time = datetime.fromisoformat(pickup_start_time)
            pickup_start_time += timedelta(hours=2)
            pickup_start_time = pickup_start_time.isoformat()
            self.tgtg_answer["pickup_interval"]["start"] = pickup_start_time
        except ValueError:
            pass
    
    # time shift forward by 2 hours for pickup_end
    pickup_end_time = self.tgtg_answer.get("pickup_interval", {}).get("end")
    if pickup_end_time:
        try:
            pickup_end_time = datetime.fromisoformat(pickup_end_time)
            pickup_end_time += timedelta(hours=2)
            pickup_end_time = pickup_end_time.isoformat()
            self.tgtg_answer["pickup_interval"]["end"] = pickup_end_time
        except ValueError:
            pass

    self.store_name = self.tgtg_answer["display_name"]
    self.item_qty = self.tgtg_answer["items_available"]

Time zones are a difficult problem in general.
It looks like the timestamps that come back are always UTC (and end in "Z")
It's probably tolerable for parts of the year in parts of Europe. But anywhere else in the world, the timestamps are pretty useless as-is.
Of course it's quite possible that most people just use it to see if anything is visible, and if so, go and get it.

Here's a minimalist approach to fixing the times:
Add this with all the other from/import statements at the top of sensor.py
from dateutil.parser import parse
And then wrap all three of the lines that transfer the timestamp data in
parse( and ).astimezone().isoformat()

So the whole block (starting around line 180) looks like this

        if "pickup_interval" in self.tgtg_answer:
            if "start" in self.tgtg_answer["pickup_interval"]:
                data[ATTR_PICKUP_START] = parse(self.tgtg_answer["pickup_interval"]["start"]).astimezone().isoformat()
            if "end" in self.tgtg_answer["pickup_interval"]:
                data[ATTR_PICKUP_END] = parse(self.tgtg_answer["pickup_interval"]["end"]).astimezone().isoformat()
        if "sold_out_at" in self.tgtg_answer:
            data[ATTR_SOLDOUT_TIMESTAMP] = parse(self.tgtg_answer["sold_out_at"]).astimezone().isoformat()

This will convert the timestamps to the timezone of the server that is doing the processing. That should be good enough for many people.
Since it doesn't make any other modifications, the same template that is already in use should just do the right thing.

Fancier changes can be left to the reader, or myself if I get ambitious.

Looking more closely, could presumably also use datetime.fromisoformat() instead of parse()
No idea which one to prefer. But I like the astimezone() as a more official way of handling it (can always create a timezone to pass in that represents your particular offset if you don't want the server timezone)

WOW!, thanks alot for the help, should be a inherent part of the component! Thanks!

Actually Home Assistant integrations are always supposed to feed data as UTC. I was looking into it as I also noticed it displayed the time with a 2 hours difference. However, this was only on my dashboard (with a custom template) while the attributes in the entity shows it correctly. Apparently the template (which is also documented in this repo) just cuts up the string with pickup_end[11:16]. Proper timestamp handling would use a a proper filter/function: https://www.home-assistant.io/docs/configuration/templating/.
