Add manual switch to TY-08Z 8 channel zigbee relay

I’ve just turned on a zigbee 8 channel relay with RF, digital/analog inputs and RS485 control. Model no. TS0601 as reported by HA. Seller’s model is TY-08Z. Manufacturer has a config menu using Tuya Smart life. I’m trying to use it with my home asistant.
I’m unable to activate the manual switch buttons under home assistant system.
Appreciate if any user has experience of this nature can advise. Thank you

There is a core Tuya integration and several Contributor supplied Custom Integrations for Tuya that are available from GitHub by using the HACS interface.
