[gunoid]

@hillaliy Could you pls share your experience with Moes floor heater.
Did you flash HAA firmware over Tuya original with this json? How does it work with Homekit?

[jmgutierrezc1]

Sorry guys, some more information. Just found that the chip that Came in the thermostat is not a TYWE3S, which is ES8266 based, but a WB3S, BK7231T based., This is the reason I could not flash this chip and probably why the messages coming from the thermostat (temp. reading and manual changes in the thermostat) are NOT coming back to homekit. Thoughts?

[hillaliy]

Maybe Tuya changed the serial commands. You need to check it.

[jmgutierrezc1]

Totally unfamiliar with configuration of UART messages, would not know where to start. Unfortunately I already have the esp replacing the other chip and half way there. Can someone recommend where to get information.

[hillaliy]

You won't find it on the net. If I have one of this switch model I can get the serial commands.

[jmgutierrezc1]

What tools/process do you recommend for that?. Thanks

[GPL71]

Is display working with HAA?
What this MEPLHAA do?
Thank you

[hillaliy]

The buttons and the LCD control by the MCU chip, so it's work with HAA

[pilot1981]

@hillaliy are you sure you are using BHT-002-GB? It don’t have WIFI connection?!

[hillaliy]

Hi this is what I'm using

₪ 96.22 45％ Off | WiFi Thermostat Temperature Controller LCD Touch Screen Backlight for Electric Heating Works with Alexa Google Home 16A
https://a.aliexpress.com/_EuL9vIJ

[GPL71]

Hello ...
Is it possible modify steps from 0,5 to 0,1?
Although manually display could show 0.5 steps, HAA could send a better regulation
Another question
Is it possible set in MEPLHAA "Z": for offset?

[hillaliy]

you can change the MEPLHAA as you want

[GPL71]

you can change the MEPLHAA as you want

Ok but how to?
55aa0006000802020004000000 1c31-->it's 14.0
55aa0006000802020004000000 1d32-->it's 14.5

What is for 14.1, 14.2, 14.3, 14.4?
And does BHT accept that steps? Or it know only 14.0, 14.5, 15 ...?

And what is this code? 55aa00060008020200040000001f34
Is it something likes a HAA IR capture?

thank you

[hillaliy]

The device is not support x.1, x.2 ....
this (55aa00060008020200040000001f34) is UART command

A lot of people don't understand the UART protocol. I think to make a live stream on Youtube to explain this.

[GPL71]

Ok .... then even insert the offset "Z" will not works

[hillaliy]

[GPL71]

thank you

[hillaliy]

The MCU control everything you can't change the program on the MCU.
When you flash HAA it's on the TYWE3S chip. it's send and receive commands from and to the MCU.
The hex command - 55aa00060008020200040000001f34
So you need to fit HAA to the MCU program

[GPL71]

yes ... I understood that. I thought was possible send a better temperature command via UART
Thank you

[Bolshoylu]

Can you convert this script for new firmware version 12 merlin?

[hillaliy]

{"c":{"r":[{"n":10,"s":9600}]

[Bolshoylu]

Thanks a lot

[borissov]

I flash Moes with HAA and this config but the clock always starts from 00:00 and in HomeKit shows one additional thermometer always on 0 degrees..Any ideas what isn’t working?

Thermostat is BHT-002-GCLW.

[borissov]

Stay only in setup mode, and not boot in my case.

[RavenSystem]

There was a typo. Now, it is fixed.

[borissov]

Is there a way to synchronize the clock using the NTP service? Is it also possible to change to the "manual mode" when switching from HomeKit?

[borissov]

Is it possible around 00:00 for the ESP to send a command to the Tuya controller to set its clock to 00:00, so that once a day the ESP's NTP clock synchronizes the Tuya controller's clock?

[MrJelly17]

Hi. This is exactly what I was looking for. I have the same thermostat. Would you be able to provide some guidance on where to start please

[jmgutierrezc1]

what pin has th temp sensor?

[hillaliy]

If you mean PGIO? There isn't!
It's work with serial commands

[jmgutierrezc1]

I see thanks. I am not familiar with UART communication with the MCU

[teotulip]

In the new thermostats as we know, the new TYWE3S chip is mounted which I replaced by unsoldering it with an esp8266 and loaded the HAA firmware
Once ready I loaded the script reported by @RavenSystem here: #1834 (comment)
It works and takes the command correctly from Homekit, but the temperature sensor remains at -99°, even the external sensor, which I will not use, remains at -99°
What's wrong? can the UART commands coming from the device be changed?

[hillaliy]

Moes changed the chip to WB3S (BK7231T). You will be able to send command from HomeKit but HomeKit won't get info from Device. If you turn on from the button you don't get the status on HomeKit. No solution yet.

You're right, I didn't notice it was one-way.
Too bad.
