Tuya integration - Multiple accounts

I finally managed to get HA to pick up my Tuya devices (not sure how, it just started seeing devices). However, I had an issue with one device that refused point-blank to connect using the Smart Life app. In the end, I used the Tuya app. From the integration’s perspective, it sees 2 accounts:

Clicking on the first account:

However, clicking on the second account:
No devices. However, clicking … > reload:

My device is found.

But, my 11 devices are lost.

It’s not some UI bug as I have set up a script to toggle the switch on one of the 11 devices and the single device. The script only actions devices in the “reloaded” account.

This feels like a bug in the integration, as it’s able to detect two accounts. Apart from re-syncing all 11 devices from Smart Life to Tuya, can anybody suggest a solution, please?

In the logs I see:
When account with 1 device is “reloaded”:

2022-12-12 23:43:55.633 WARNING (MainThread) [homeassistant.helpers.service] Unable to find referenced entities switch.back_door_light_socket_1 or it is/they are currently not available

When account with 11 devices is “reloaded” (this is the 1 device):

2022-12-13 00:00:22.352 WARNING (MainThread) [homeassistant.helpers.service] Unable to find referenced entities switch.garage_ext_lights_switch_1 or it is/they are currently not available


Hi have the same issue, did you find a solution ?
I want to link my Smart Life and Tuya app. In the IOT plaform they are linked but in HA It’s the issue as explained above.

Sorry for not replying sooner.

In the end, the SmartLife app decided to behave itself.

I guess the Tuya Integration maintainers don’t frequent these forums too often and the GiHub repo covers the whole of Home Assistant, so there are 2000+ open issues. One can filter by integration and that leaves 110 issues for Tuya, so I guess a request to properly support multiple instances or fix the bug (depending on how one looks at it), is low on the list.

Sorry, I can’t be of any assistance here.

Same problem here. I can’t use Tuya Smart and Smart Life on the same Tuya integration, because only one at a time can have devices connected.


Anyone managed to find any solution to this problem?

Two Tuya accounts (account_1, account_2) with respective devices/scenes etc

create an account_3
in account_1, configure a family with own devices of account_1.
in account_2, configure a family with own devices of account_2
in account_1, invite account_3 to family as admin
in account_2, invite account_3 to family as admin
in account_3, accept both family invites
in HA, include ONLY account_3 using Official tuya Integration, all devices from both accounts will be included

2. Only compatible with same app (2 Tuya accounts OR 2 Smartlife accounts)
1.Currently working fine in my HA, needs more testing, especially with devices that have the same name in both accounts. (HA puts _2 in entity but I’m not sure it’s guaranteed to point to the correct device)


Thankyou rafareusch (Rafael)
Today I run in to it, and took your solution and all works just fine. Great idea.
