Tuya / Eurom Heater device visible but no entities

The problem

Since the update to new tuya integration my climate / heater “Eurom Heater (wlAXJ1H2Mh7Qrs0I) by Tuya” is visible within the devices but without any entity.

I can control the heater directly from Tuya App on my SmartPhone, but not from Home Assistant (as there are no entities).

What version of Home Assistant Core has the issue?

2021.12.7

What was the last working version of Home Assistant Core?

2021.9.7

What type of installation are you running?

Home Assistant Supervised

Integration causing the issue

Tuya

After multiple more contact with the Eurom support I received the following reply today:

So it seems like somebody is working on it from Eurom side - not fully clear about the timeframe. @frenck: Not sure if you are ok with keeping this issue open in meantime, or if I should close and just come back after Eurom fixed the issue / gave a final reply.

To add to my above response, this is a EUROM heater I personally have and own for testing with Home Assistant. This one works, so it seems that EUROM was aware at some point, as the firmware running on this device does work correctly with the Tuya APIs.

To me, it sounds like EUROM needs to support/fix their older devices and ship a firmware update.
