phy6222 controller support. #268

Jarled · 2022-11-20T11:48:34Z

I bought the newer version of this sensor and it seems to be using a PHY6222 controller, could get it working on this please?
http://wiki.phyplusinc.com/doku.php?id=menu:phy62_series:phy6222

pvvx · 2022-11-20T20:27:05Z

The PHY6222 has a higher consumption (13 uA) than the TLSR825x (1.8 uA) in sleep mode with active SRAM. Also, the PHY6222 software and hardware has an increased SoC wake-up time - the result is an even higher average current.
Thermometers with TLSR825x in combination with an LCD/E-Ink driver and sensor have a sleep current of up to 9 µA.
With PHY6222, battery life will be significantly reduced... Unsuccessful option.

The protective sticker installed for protection during installation has not been removed from the temperature and humidity sensor :)

Is this some kind of fake Xiaomi LYWSD03MMC?

Jarled · 2022-11-20T20:38:55Z

i dont think so, its meant to be a Bluetooth 5.0 BLE version

pvvx · 2022-11-20T20:41:20Z

Oh, it's Tuya :)
For Tuya, any hacky manufacturers are produced ...
TLSR825x - Bluetooth 5.0+

pvvx · 2022-11-20T20:53:43Z

Another "miracle" BLE thermometer CX0726B:

It has CR2032, but the average current in ad mode is 80 uA. And when connected to a regular Chinese program, the average current is 0.8 mA. Ten days of battery life :)
Temperature and humidity transfers only when connected. (This is for all Tuya)

Jarled · 2022-11-20T21:06:11Z

i have no experience in this space, if someone can help me remove the bluetooth bind key bit and i can add it to HA.

pvvx · 2022-11-20T21:07:48Z

Temperature and humidity transfers only when connected. (This is for all Tuya)
"Keys" are usually not required for this.

You can officially get the keys to any Tuya device on their website https://iot.tuya.com/.

You need to register.
1 Cloud - device list… get id
2 API explorer -> Smart Home Management System-> Device Management -> Get device details … Sybmit ... use id

I have not seen integration to HA for Tuya BT/BLE.

Thanks, i got that info now, is there a browser page i can test with the local key ?

I will post data on TX-05 in https://pvvx.github.io/TH-05/

@Jarled - Why not write about support in HA LocalTuya?

Jarled · 2022-12-09T14:07:30Z

What do you want me to write, have you managed to get it working ?

pvvx · 2022-12-09T14:45:49Z

TH-05 consumes a lot in operating mode: Average 33.4 uA
After registration in "Smart Life": Average 43.2 uA (!)

Minimum chipset power consumption (sleep mode, datasheet):
PHY6222QC-W04I - 13uA @ Sleep Mode with 32KHz RTC and all SRAM retention
BL55028 - 9 uA
Sensor? - 1 uA?
Total: above 23 uA (A lot for CR2032. Half a year maximum?)
Writing a program for such equipment does not build time. Such products (Tuya) go to the trash.

Smart Life

Jarled · 2022-12-09T18:48:24Z

Can these be added to Home assistant via BTHome or will it require creating a new program ?

Jarled · 2022-12-09T19:06:22Z

ok but what about doing it via ESPHome instead ?
https://esphome.io/components/sensor/xiaomi_ble.html#lywsd03mmc

pvvx · 2022-12-09T19:43:25Z

No way. It requires creating a new program for PHY6222 and (wired) flashing the thermometer, which is not worth doing for this chipset version. It is not suitable for long work from CR2032.

pvvx · 2022-12-09T20:40:54Z

When temperature or humidity changes, TH-05 transmits data to BLE advertising encrypted using the Tuya protocol.
HA requires integration that supports BLE Tuya.

cconde · 2023-06-05T18:20:43Z

We shouldn't expect this great firmware on this device soon, isn't it?

pvvx · 2023-06-07T07:26:01Z

In this repository and TelinkMiFlasher.html Telink SoC devices are supported.
There is no gcc on the PHY chipset. Only proprietary paid Keil.
That is, there can only be an internal non-public or paid version.
No one is doing Taya BLE (OTA), and there is no interest in doing it alone.

According to the datasheet the RAM is split up into three blocks (32kB + 2 x 16kB) that can be switched off individually. So with only 16kB enabled I would expect a power consumption of 1uA + 1/4 * (13uA - 1uA) = 4uA. So for the whole device 4uA + 9 uA + 1uA = 14uA. Sounds reasonable?

serpent213 · 2023-06-30T14:43:33Z

The actual money shot:

pvvx · 2023-07-01T11:50:47Z

According to the datasheet the RAM is split up into three blocks (32kB + 2 x 16kB) that can be switched off individually. So with only 16kB enabled I would expect a power consumption of 1uA + 1/4 * (13uA - 1uA) = 4uA. So for the whole device 4uA + 9 uA + 1uA = 14uA. Sounds reasonable?

Cycle 2.5 sec:
14 uA sleep mode - 2495 ms
6 mA active mode - 5 ms (аctually more *)
( 6 * 5 + 0.014 * 2495 ) / 2500 = 0.025972 mA

The measurement time of the AHT 20 sensor is from 80 ms (AHT20 Product manuals). The original firmware uses 102 ms.

102 ms ->

If we recalculate the specified values in the "AHT20 Operating Manual" for a polling period of 10 seconds, then only the AHT20 sensor will consume at least 5 µA. In reality, according to measurements, it turns out more.
PHY62xx/ST17H66 chips take a long time to wake up from sleep. This is due to the code in the SDK. This increases the time of the active SoC mode. As a result, consumption increases a little more (when compared with other BLE SoC).

As a result (according to theoretical calculations), if the BLE advertising interval of 2.5 seconds is used, the sensor is polled every 10 seconds and 16 kilobytes of RetRAM, the average consumption will be approximately 31 µA .

So conclusion is?

almirus · 2023-12-15T20:16:10Z

@pvvx How long did the device ultimately last on battery?

Looks like there's Community Edition of Keil - can you not release code using community edition as open source? https://www.keil.arm.com/community/

pvvx · 2024-01-07T06:17:36Z

Everything has already been decided. For PHY62x2, GCC sources are collected with RF library sources.
An implementation for GCC will be available soon at https://github.com/pvvx/THB2.
Currently, this repository contains a test version only for Keil.

pvvx · 2024-01-07T09:08:48Z

https://github.com/pvvx/THB2 обновлен для сборки в GNU Arm Embedded Toolchain.

Обойдется. Мне Keil не нужен.
Обошли - китайцы дали исходники для либ и теперь можно собрать в GCC.
Но всё последующее ПО (типа OTA) для PHY62x2 будет только на русском языке.

pvvx · 2024-01-24T20:36:04Z

Первая тестовая версия уже на https://github.com/pvvx/THB2
Все обсуждения туда.

Возможно ли что то сделать вот с таким датчиком pvvx/ZigbeeTLc#53 ? Чип TLSR8250 и SH40. Если нужна еще какая то информация, предоставлю, все что потребуется. :) Хотелось, бы его как то подружить с HA, а то, все что смог найти интеграции "tuya ble" - не работают с ним...

pvvx · 2024-02-06T19:48:30Z

У меня такого нет. Ради одного датчика никто шевелиться не будет, только если сами возьмете исходные коды и поправите под свой вариант.
