Wi-Fi relays for more flexibility and PUMPs

Could indeed be usefull. Most of what you want is already possible with the current version and plugins.
I would suggest to expand (or rebuild) the MQTT part of SIP.  With mqtt you could also interact with the Shellies. I do so too but have node-red in between (most of) everything.

The one option missing now is a versatile activate multiple but not all valves or other devices. That is a bit tricky to implement (at least I think so) because it is a core functionality and many plugins depend on it. @Dan can say much more about it.

Gerard,
Could you provide more details about "a versatile activate multiple but not all valves or other devices"?
Is this something different from what the combine_stations plugin does?

You are right, I had forgotten this one and even discovered a bug in my pcf i2c plugin. The virtual stations are also treated like a normal station. I will update the plugin in the coming month(s) when I'm back in the country.  
Still, I have some ideas which includes multiple masters, sensors, actuators etc. But I won't hijack Pedro's thread for this :-)
