I’m a newbie here so apologies if this is wrong section of the forum. I’ve just set up homeassistant in a virtual machine on my pc and everything seeme to be working fine. My dashboard is very basic and I’m playing around. I have always got into a mess when trying turn my givenergy system off and then on again, either by the app or the cloud. For instance, when there is an hours free electricity I turn my system off and change my EV for an hour and then turn the system on again. (My system being a gen 1 inverter and two batteries). I am attempting to put an on/off switch on my homeassistant dashboard. I have the switch showing and the MQTT control configured is Enable Charge Schedule. Is this the right entity to turn my system off and on? Any help appreciated.
I’ve just added a battery discharge button - using the givtcp element number.givtcp_sa2104g071_battery_discharge_rate
To turn ‘my system off’ as such, do I just slide where the arrow is all the way to the left?
Personally I’d consider either charging your battery in the free electricity period, at a low charge rate, which you can do with some automation in Home Assistant.
Failing that, you can just use the “Battery Pause Mode” option and set it to “PauseBoth” so it will neither charge nor discharge; thus running your system from grid power. Just don’t forget to set it back again!
Thank you - that is very helpful. My situation is where, in the summer, my battery is 100% (due to solar) and there is a free 1 hour session. Obviously if I just plug in the EV it will drain the battery - I like your suggestion of using Pule Mode. Thank you.
Welcome to the Home Assistant rabbit hole 
The real strength of HA is getting it to do things so you don’t have to. Have you researched if there is an integration in HA for your EV or wall charger?
If there is, and if that integration has a sensor that reports when the car is charging, then you can build an automation within HA which monitors that ‘Car is Charging’ sensor and sets the GivTCP ‘Battery Pause Mode’ to prevent discharge during a car charging session, and then enable discharge again when it finishes.
It can feel like a lot to get your head around HA initially but take your time. When it works the first time it feels like magic
