Xiaomi flowerpot support (Ropot, HHCCPOT002)

[Magalex2x14]

Would it be possible to read data from a smart flowerpot from Xiaomi (Ropot)? I have the HHCCPOT002 version. This product appeared on the market at the same time as Flower Sensor. It only measures the moisture and conductivity of the soil. Has a built-in rechargeable battery.

@kleju00 Hello! Since I do not have this device, some information is needed. Here is the data collection instruction:

• make sure that there are no sensors of a different type (from the ones listed above) in the reception radius, except for one you are interested in supporting (optional, but desirable);
• run the following commands on the command line: sudo hcitool lescan --duplicates --passive and at the same time sudo hcidump --raw hci > dump.txt
• remember the sensor readings during hcidump operation (approximate);
• after a couple of minutes of work, abort hcidump using CTRL+C;
• send me the resulting dump.txt file and approximate sensor readings (preferably a cloud storage link, but it can be by email or something else);

I have a problem eliminating all BLE devices because I have a lot of them. I used the Android application and captured some RAW data from this particular device:

0x020106030295FE141695FE71205D010D0D0C6D8D7CC40D091002A8000609726F706F74 0x020106030295FE141695FE71205D01490D0C6D8D7CC40D091002A7000609726F706F74 0x020106030295FE141695FE71205D012B0D0C6D8D7CC40D091002A9000609726F706F74 0x020106030295FE141695FE71205D01390D0C6D8D7CC40D091002A8000609726F706F74

The device was not connected to the phone and the BLE gateway from my Xiaomi Humidifier was turned off.

Real Soil moisture ~45 % Real Soil fertility ~170 uS/cm Battery level - 76%

Previously I used SmartThigs SmartApp which supported this pot. https://github.com/fison67/mi_connector/blob/master/devicetypes/fison67/xiaomi-flora-pot.src/xiaomi-flora-pot.groovy Maybe it will be helpful. If this is not enough, I will try to figure something out.

It's okay if there is no such possibility. I’ll find the packets I need anyway. It would be more convenient for me to work with the hcidump dump... If possible, do it. I can tackle your question closer to the end of this week (now busy with #9). As far as I can see, there should be no problems with the implementation of the support of your pot.

[kleju00]

Thanks a lot. I will try hcidump tomorrow.

[kleju00]

This is my hcidump.txt

Real Soil moisture ~0 % (this reading sometimes breaks, connecting the charger helps) Real Soil fertility ~162 uS/cm Battery level - 76%

The file should also contain data from my LYWSD03MMC.

How long is this dump? About seven minutes? You right, It seems that the pot behaves in the same way as miFlora (data 1-2 times per minute, no information about the battery). I also see data from the MiFlora sensor (HHCCJCY01). I do not see LYWSD03MMC (but it doesn’t matter, everything is complicated with its support so far).

Pot support will be added in an upcoming 0.4.3 release (today).

How long is this dump? About seven minutes?

I thought it was 3-4 min. Ropot sends data about twice as often as Flower care. Look:

I also have one CGG1. Thanks again for the quick help.

[Magalex2x14]

Released

Ropot sends data about twice as often as Flower care

Thank you for your participation! Feel free to reopen issue if needed!

LYWSD03MMC discussion here #7

[kleju00]

I tested the new version and found a problem:

No conductivity entity, instead there is a inactive temperature entity. The humidity is read correctly.

[Magalex2x14]

Very strange... how much time has passed since the launch of the new version of the component? Please, check MAC address carefully (entity ID) - must be C4 7C 8D 6D 0C 0D

[kleju00]

It looks like MAC is right. I updated to the new version as soon as it appeared in HACS.

[Magalex2x14]

Yes, I think I was a little hurried... Give me a little time, I seem to have found the root of problem...

[Magalex2x14]

@kleju00 please, reinstall 0.4.2 version through HACS. After you make sure that the correct entities appeared, the wrong one can be deleted through Configuration -> Entities

[kleju00]

Now I have:

• soil moisture value in the conductivity entity
• no value in soil moisture entity
• the temperature entity has itself deleted after restart ha

I'm using hassio on rpi3.

[Magalex2x14]

Yes, the problem is deeper than I thought. Sorry, the day was too long yesterday )

[kleju00]

Do not worry. It's nice that I can help you. When I get home I will give you the firmware version from the pot (complete information).

[Magalex2x14]

@kleju00 please, reinstall 0.4.2 version through HACS.

[kleju00]

Everything seems to be working. thx

Firmware version: 1.2.6

[Magalex2x14]

Thank you. Let's watch a little bit. Just in case )

[kleju00]

It still works. You can close.
