missing field `re_power_type

[zaraquer]

Hi!

I recieved this error booth on rust and python examples on L510 bulbs.
Error: Serde(Error("missing field re_power_type", line: 1, column: 550))
I want to use the client to monitor the power usage of the bulbs.
What can I do to fix this issue?

[mihai-dinculescu]

It looks like this is a regression of the change in #135.
Can you please call get_device_info_json instead of get_device_info, and paste the output here?

[zaraquer]

After I changed get_device_info to get_device_info_json it works great.:

2024-01-19T09:11:54.974Z INFO tapo_l510 > Device usage: DeviceUsageEnergyMonitoringResult { time_usage: UsageByPeriodResult { today: 28, past7: 1211, past30: 13237 }, power_usage: UsageByPeriodResult { today: 1, past7: 172, past30: 1829 }, saved_power: UsageByPeriodResult { today: 27, past7: 1039, past30: 11408 } }

Thanks for the help and your great work mate!

[mihai-dinculescu]

Sorry, the output that's pasted above is for device usage.
Can you please provide the one for device info?

[zaraquer]

Sure, I just changed the sensitive parts.

Device info: Object {"avatar": String("bulb"), "brightness": Number(30), "default_states": Object {"brightness": Object {"type": String("last_states"), "value": Number(30)}}, "device_id": String("8023C0D888DD972F67F68BF0809ABE791EF4B5E0"), "device_on": Bool(false), "fw_id": String("7BECA9DC454565672FEC87D1104F9972"), "fw_ver": String("1.3.0 Build 20230831 Rel. 75926"), "has_set_location_info": Bool(true), "hw_id": String("93F94D88DA9499F43B929DD38EBDF09A"), "hw_ver": String("1.0.0"), "ip": String("xx.xx.xx.xx"), "lang": String("hu_HU"), "latitude": Number(21412431), "longitude": Number(212141), "mac": String("11-11-11-11-11-11"), "model": String("L510 Series"), "nickname": String("S29ueWhh"), "oem_id": String("6B97E8E19CE8019B59D9E81CEDD371BD"), "on_time": Number(0), "overheated": Bool(false), "region": String("Europe/Budapest"), "rssi": Number(-46), "signal_level": Number(3), "specs": String("EU"), "ssid": String("V29yay1OZXR3b3Jr"), "time_diff": Number(60), "type": String("SMART.TAPOBULB")}

Not fully okay as I see it now, because it wont get forexample the nickname correctly.

[mihai-dinculescu]

Thank you, this is very helpful.

The get_device_info_json function gives the response as it comes from the Tapo API without trying to parse it in any way. Decoding the nickname is part of the parsing that get_device_info does.

I know what needs changing now. re_power_type seems optional.

[mihai-dinculescu]

The fix has been released in Tapo Rust v0.7.8 and Tapo Python v0.1.5.

[mihai-dinculescu]

@zaraquer, it would be lovely if you could try out the new version. I suspect that there might be some further errors :(

[zaraquer]

Thanks! I will check it today a bit later. Sorry for the late answer, I was away from my computer. BTW thanks again for your fast and amazing work!

[zaraquer]

I tried the python version first.
With get_device_info:

Traceback (most recent call last):
File "/root/tapo/tapo-py/examples/tapo_l510.py", line 40, in

device_info = await device.get_device_info()
Exception: Serde(Error("missing field re_power_type", line: 1, column: 539))

After I changed it to get_device_info_json:

Traceback (most recent call last):
File "/root/tapo/tapo-py/examples/tapo_l510.py", line 40, in
asyncio.run(main())

print(f"Device info: {device_info.to_dict()}")
AttributeError: 'dict' object has no attribute 'to_dict'

[mihai-dinculescu]

Are you sure you're using the latest version? I'm surprised to see the missing field re_power_type error occurring.

to_dict is required only on the result of get_device_info.
get_device_info_json returns a dict straight up, so you should not call to_dict on its result.

[zaraquer]

Yeah, its the latest.

[zaraquer]

Okay, I deleted dict, now this is what I get:

[mihai-dinculescu]

Hmm, before running the example, can you please run

cd tapo-py
poetry install
poetry shell
maturin develop

and try get_device_info again?

[zaraquer]

I did what you suggest:

(tapo-Q5KVV4uC-py3.10)~/tapo/tapo-py# python examples/tapo_l510.py

[mihai-dinculescu]

That's brilliant, thank you. This error does make sense, and it's what I was afraid of.
I'll have a fix in the next couple of days.

[mihai-dinculescu]

The fix has been released in Tapo Rust v.0.7.9 and Tapo Python v0.2.0.
