Is there such a thing as a gadget like a wireless remote control that can be triggered by the inverter relay to switch on and off smart plugs and switches that are also controlled by Alexa? I have an immersion heater smart switch that is linked to the smart life app and to Alexa, but it would be great if the MultiPlus-II could also control this switch via the relay. Is thete anything available?

Please describe why an inverter should switch a single or several devices ‘smart’?
You could switch the multi, but does it make sense the other way round? For the activation of e.g. a water heater, this can be done via the assistant and / or relays …
You have to build the necessary external controls yourself … Integration of NodeRed and or a Raspberry controller with additional functions.
The Multi is primarily just an inverter …
The idea is to switch on the immersion heater via a wifi smart switch once the batteries are full, to divert the extra solar to the hot water tank, or to switch on a space heater automatically.
The inverter is too far away to add hard wired connections to the immersion or space heater, so a smart switching system would be ideal if it can be triggered by the mp2 relay after setting up an assistant.
If you have a CerboGX then you can do this with a Shelly device and NodeRed relatively cheap.
Do i jave to use node red with the shelly? Or will assistant work? Node red is too mind boggling to me
The shelley can be triggered the same way it would if you wired it to a light switch.
The assistant though are you wanting to use SOC?
Yes soc will be needed as the trigger. What relay would i need to connect it to?
You could use k1
Can you please explain what/where k1 is, where can i find info about k1?
Sorry @mfred868
The MP2 does not have the k1. I forgot that.
Connection overview
Just change the relay in the assistant to whatever one you physically have on your unit. Even the t sense will work.
