[BUG] smart relays switch entity duplication issue after upgrading from HA 2026.1.3 to 2026.2

[cb2206]

Bug description

I have a bunch of Zigbee smart relays - two types:

1 channel (around 35 of these) - zhaquirks.tuya.ts000x.Switch_1G_Metering:

4 channel (3 of these) - zhaquirks.tuya.ts000x.Switch_4G_GPP:

After initially adding them to ZHA 6+ months ago, they showed up as lights. I changed the device type through configurations.yaml:

This all worked fine from mid 2025 through all monthly HA updates until 2026.1.3. After upgrading from 2026.1.3 to 2026.2 last night, within each device the original switch entity I have been using the last 6+ months showed as unavailable and a new entity was created with the same name + “_2” at the end. As it was later at night when I noticed and our heating system is controlled by those relays, I restored the 2026.1.3 backup without taking additional logs/screenshots.

Is this a known issue? Anything I can do to prevent this from happening?

Steps to reproduce

Upgrade HA from 2026.1.3 to 2026.2

Expected behavior

not duplicating switch entities after upgrade

Screenshots/Video

see above

Same situation here using this relay "TS0001 by _TZ3000_p26flek3" and this quirk "zhaquirks.tuya.ts000x.Switch_1G_GPP".
Relay configured as "switch" in configurations.yaml.
Relay control got duplicated, "power on state" configuration is no longer provided.
Heating automation triggered (or tried to) the old disabled control :))...woke up in 17 degree environment. :))
Situation "fixed" by changing automation action entity.

That issue is unrelated. It's a behavioral change with ZHA which we'll revert shortly. As a temporary workaround, you should be able to append -0 to the config, so it should be <ieee>-<endpointId>-0. But note that this will break again when we make the fix/revert.

It has already happened to me with these devices and I have set them all up from the start. When you do this revert, will I have to set it up again?

I described my issue here.
My configuration.yaml:

zha:
  device_config:
    XX:XX:XX:XX:XX:XX:XX:XX-1:
      type: switch

After replacing XX:XX:XX:XX:XX:XX:XX:XX-1 with XX:XX:XX:XX:XX:XX:XX:XX-1-0, all entities became available, but the "light" entity type is not converted to the "switch".

Thank you. What's the rough timeline? Will that go into 2026.2.1?

Most likely 2026.2.2.

I have the similar with recent HA versions.
If I have ZHA config defined to change the problem device from Light to Switch. It will prevent this device to be properly controlled by ZHA. The whole entity and controls becomes unavailable. Once removed the ZHA device type config, the device in ZHA works fine but shown as Light.

Just curious why this zhaquirks/tuya/ts000x.py defined as Light? Isn’t it just a simple 1 gang relay switch by the name? Quirk: zhaquirks.tuya.ts000x.Switch_1G_GPP

Most likely 2026.2.2.

is it out yet?

Update: just tested it with 2026.2.2... still not working. Entity is exposed as light, but should be switch (via override) and my _TZE200_rmymn92d quirk does find my covers, but they just dont respond to any commands. Must be somehow related, stopped working with the 2026.2. Strangly home-assistant/core#162894 is merged and should be part of 2026.2.2 already.. so are there more issues or what's wrong on my side?

26.2.2 fixed the issue for me. I'm updated from 26.1.3 and no new entities created. I have XX:XX:XX:XX:XX:XX:XX:XX-1 's in my config.
