if you will use home assistant software, you can chose KC868-A series ESP32 board. But if you MUST want to use google home voice control freely. I suggest use chose KC868-H series board, such as KC868-H32B Pro relay controller, because that use by tuya app, it can use google home and alexa voice controller directly. you can integrate to home assistant by MQTT.

1. you can use KC868-Server to install home assistant, zigbee USB dongle connect to KC868-Server, so that you can use zigbee2mqtt in home assistant.

2. use KC868-H32B Pro + KC868-E16v2 extend relay module for larger current load + KC868-AK for manual control buttons (for your wall momentary switches)

3. for air conditioner or IR device, you can add KC868-AG Pro, that support control IR by home assitant or Tuya app at the same time, also it's Zigbee3.0 hub inside.

thank you very much for answer!

ad.1 I have already bought terminal hp t620 because it was suggested on some smart DIY fb groups  would it not work? is KC868-Server better?

ad.2 thank you I will go for it! But only for my understanding - I`m wondering what are this KC868-AK module features/benefits comparing to KC868-A8 besides onboard S1-S35 buttons. For instance having momentary switch connected to KC868-A8 wouldn`t I be able to create double/long click scene in HA/esphome and upload it to KC868-A8 ??? 

Also some last question came to me. Lets assume I have solution which you have suggested in ad.2 than if KC868-H32B Pro will die all my lights/roller shutters will stop to work - am I right? 
Maybe it would be better to connect somehow KC868-H32B Pro with KC868-A8 (maybe even better mosfet KC868-A16 with KC868-E16V2) modules so if KC868-H32B Pro gonna die (or some other unexpected things happen) than I will still have possibility to turn on lights/blinds ? Because as I understand using esphome I will be able to upload code to KC868-A8 (as local config) and it will work independently even without controller or network?
