core: MoesGo WiFi Thermostat is not properly controllable using the new Tuya integration

Home Assistant 2022.2 (now in beta, feel free to join!), will have a diagnostics dump tool on the device page, which contains information to share in issues like these.

It can be helpful if all of you having issues with these MoesGo thermostats posted their diagnostics results here. I will allow finding a solution (or worst case, conclude there is none).

Thanks Frenck for all your work

Update on the Tuya Developer IoT Platform / App solution:

• I got a response from Tuya support that:

What is displayed on the APP is the manufacturer’s customized panel, which is defined by the manufacturer during production. The manufacturer does not define the current_temperature directive, and this does not meet the cloud standard. This is the cloud standard instruction document: https://developer.tuya.com/en/docs/iot/f?id=K9gf45ld5l0t9

• I wrote to the manufacturer’s - MOES House - support. The good thing is that they replied right away with request to provide more info. The worrisome thing is that it’s been a week since I replied and they haven’t responded anymore. Still trying…

UPD 01.27: I got a message that the delay in response is due to the Chinese New Year holidays, which according to the web are:

Celebrations of Chinese New Year traditionally last for 16 days, starting from Chinese New Year’s Eve to the Lantern Festival. In 2022, that is from January 31st to February 15th.

As a public holiday, Chinese people will get 7 days off from work from January 31st to February 6th in 2022.

Traditionally Chinese Lunar New Year activities started as early as three weeks before Chinese New Year’s Eve. Old-fashioned (mostly rural) folk start cleaning their houses from the 23rd of the twelfth lunar month (January 25th, 2022).

@frenck, thanks for the update anyway.

Any chance you can add some temporary ugly workaround for 2021.11? Like an option to add an attribute __tuya_multiplier for a thermostat entity via customizations. If Tuya decides to shut down the old API before the fix is ready — everybody using the affected thermostats will have to update their automation to adjust the temperature.

P.S. I wonder how the Smart Life app works appropriately while the API has no idea about the multiplication. Also, I’m surprised that the temperature displayed in HA has to be multiplied by 5, while the temperature visible in Tuya IoT debug has to be divided by 2 to get the correct temperature 😃

Well, I have some more information. As it seems, this device has customizations, specifically for this manufacturer/device. Thus isn’t supported/being able to support the cloud API (according to Tuya).

This makes it hard to implement. From an API consumer perspective (Home Assistant), we currently do not have a way to differentiate between this device and others.

I’ve added some extra information in the upcoming Home Assistant release, that might help to find and implement a solution. But this means for 2021.11, this issue won’t be fixed.

same issues with MoesHouse BHT-002-GBLW WiFi thermostats and SASWELL SEA801 / SASWG-01-RF-WiFi thermostats:

• incorrect temperature
• not all metrics are available
• not possible to switch on / off

Hi Franck! Thanks indeed! Mine diagostic file is here: https://gist.github.com/alexanderznamensky/5168b2031998e7221cf93f7c7e897043

Thank you, Franck, for not giving up on us! 😃 Here’s what I have: https://gist.github.com/andrey-yantsen/fbf856451e0b0b36c269d334a04d36a9.

Target temperature = 19 ºC Current temperature = 21.5 ºC

@alexanderznamensky yeah, I set it up yesterday, working like a charm. I used values from https://github.com/rospogrigio/localtuya/pull/548#pullrequestreview-793253904 but removed the mode control altogether as it was somewhat broken for me. I’m using Schedy anyway, and just set the required temperature to 19ºC when don’t need the heating.

I don’t think I would be able to help you with any questions, but it definitely will be better to continue the discussion in the PR to LocalTuya and not here, to avoid being too much off-topic.

P.S. During the config flow the integration was failing to add the device, but after a few more attempts — it was indeed added.

@mowl111 nope, unfortunately, it’s not really possible. As it was said multiple times, Tuya will deprecate the old API sometime soon, and the old integration will stop working. You can try raising a ticket with Tuya (via their https://iot.tuya.com interface), but the chances are low.

As an alternative, you can use LocalTuya — they just released thermostat support today, or you can use the old integration via HACS, installing it from the repo andrey-yantsen/home-assistant-tuya-old.

Hi, I also need this one to work (for BHT-002-GCLW).

According to these tickets, it’s not very optimistic: https://github.com/tuya/tuya-home-assistant/issues/361 https://github.com/tuya/tuya-home-assistant/issues/502 https://github.com/tuya/tuya-home-assistant/issues/676 https://github.com/tuya/tuya-home-assistant/issues/675 https://github.com/tuya/tuya-home-assistant/issues/670 https://github.com/tuya/tuya-home-assistant/issues/547 https://github.com/tuya/tuya-home-assistant/issues/542 https://github.com/tuya/tuya-home-assistant/issues/535 https://github.com/tuya/tuya-home-assistant/issues/502

The main problem for me is that current_temperature is not reported at all.

Well, that’s understandable, but I had to try 😃

Thanks!

P.S. Don’t hesitate to poke me if you’ll get any ideas on how I can assist here.

@frenck yup, sorry, I forgot about it. Added to the original comment. set=23º, current=22.5º.

Hey @frenck! Thanks for the update!

I just tried the latest dev build available in docker (2021.11.0.dev20211016), and actually, it’s become a bit worse than with stable version 😃

Now I can turn the thermostat off and on, but it’s pretty much all I can do:

• The displayed temperature is still five times lower than the one shown on the thermostat (e.g. 4º instead of 20º)
• When I change the desired temperature from HA — it doesn’t get changed on the thermostat. At the same time, the integration bundled with 2021.10.4 does change the temperature
• But, at least, when I do change the temperature on the thermostat — the change is displayed by HA 😃
