Bosch Condens 3000w

Hello,
how to connect my Bosch Condens 3000w gas boiler with Home Assistant?

Hello,

not sure what network/wifi capabilities 3000w has, but I have a 2000w that has no networking capabilities, but having a wifi wireless thermostat (e.g. from Netatmo) you can integrate the boiler into HA.

I want to replace my 2 wired BUS Bosch FR10 thermostat with something to connect with HA.

As I wrote, you’ll need something like https://www.netatmo.com/en-us/energy/thermostat that connects wirelessly to a relay module (433Mhz) and via wifi to your router.
A similar product from Honeywell homecomfort.resideo.com/sites/Europe/en-gb/Pages/ProductGroup.aspx?cat=HW-TOEM&pid=Single+Zone+Thermostat,+Wireless,+T87RF-12917(HW-TOEM)&catpath=1.2.1.7.7 where the relay module and the internet gateway are different.
