Roller shutters steering with (negative) -24V DC

i think you can use A32 Pro or A32 or KC868-H32B Pro relay controller. These models all are 32 channel relay version. just A series board made by ESP32 , so that can use ESPHome with home assistant. H32B Pro use by Tuya app support voice control by alexa or google home speaker. Because all our prudoct's relay is dry contact output, so if you want output -24v, just let relay's COMOM port connect with your -24v power supply.
