Two notes: - only open standard design can operate together with not-too-much issues; - actual state of home automation is a directionless mess. About the first point: the most common protocol for "smart devices"/home appliances, those who can actually talk to something else regardless of the vendor is ModBUS, a serial protocol from the '70s. The newer MQTT, Kafka etc are very rarely supported on commercial devices. Long story short: the sole way we can get different tools from different OEMs playing together is that such interoperability is mandatory by law, carefully tested, with sanctions when found absent. Without that NO OEM will really be interoperable with anything, it's own products together included. For the second point: MOST home automation is just about flipping switches with some logic behind, the rest is just monitoring. A VERY SIMPLE THING, unfortunately almost no vendor and perhaps also most designers have no clue about how and what to automate. Even the more expensive and trendy tools, like p.v. systems to be potentially integrated with car charging systems etc aren't really integrated even under a single OEM umbrella. Essentially: just invest in home automation if you really want to do something and be prepared to long frustration, high costs and unreliable, fragile stuff.
