Configuration (old format, will be converted to new template when applied)

The Vacuum cleaner uses Dealdig App and therefor Tuya-convert is not possible. But the Wifi module is easy accessible and it’s possible to remove it from the vacuum (for debugging reasons I installed a NodeMCU back on mine Vacuum and am still running stock firmware on the original chip).

After flashing Tasmota and install the wifi module back I started receiving Serial messages immediatly without assigning any pins in Tasmota And it looks something like this AA1C06FF00040500000000000000000000000000000000000000000000505E and the messages are displayed every ~10seconds.

AA1C06FF00 seems to be defaul, 04 05 represents the state of the vacuum, 50 is the battery % in Hex you can use something like this Hex to Decimal to convert it and the 2 last bits I am not sure yet what they mean.

The Vacuum can be used sending SerialSend5 messages and the commmands are:

Smart Cleaning: aa 03 02 22 02 26
Spot Cleaning: aa 03 02 22 01 25
Edge Cleaning: aa 03 02 22 00 24 
Stop: aa 03 02 26 00 28
Go Charge: aa 03 02 22 03 27
Move Front: aa 03 02 21 00 23 aa 03 02 21 04 27
Move Back: aa 03 02 21 03 26 aa 03 02 21 04 27
Turn Left: aa 03 02 21 01 24 aa 03 02 21 04 27
Turn Right: aa 03 02 21 02 25 aa 03 02 21 04 27

The Vacuum will enter Hibernated mode after few minutes of not being in use displaying AA1C06FF000405000000000000000000000000000000000000000000006472. In this mode the battery level isn’t updated correctly and to wake it up generally I have to press the option I want a couple of time until it wakes up (generaly around 3x times)

I have added the Vacuum to Home Assistant adding the commands as a scripts and then with Vacuum Template and Lovelace Vacuum Card The yaml Package can be downloaded here: https://github.com/Sthopeless/trvc/blob/master/vacuum_white.yaml

I have also created a picture without background of the vacuum to use with the lovelace integration:
