Setting Charge Start/End Through Automation

[StraponXG]

Hi, firstly thank you so much for developing this for HA! What a great integration. Here's my install, which has been up and running with great success for a while now:

My energy supplier provides occasional free energy sessions and I'd like to be able to add these to my charge/discharge schedule automatically. I'm pretty comfortable with how to build the logic in HA, but I keep hitting a wall with how to get the hour/minute information from a variable in an automation into the charge/discharge start/end hour/minute fields within the solis_modbus integration. I can do it manually through the integration page, or if they're presented in a dashboard, but I can't figure out how to push time from a variable in automation to something like 'time.solis_s6_solis_time_charging_charge_end_slot_1'.

I've even tried to use solis_modbus.solis_write_holding_register, which I assumed would give me direct access to the modbus communication, but I get an unknown error. Here's an example that should set the first charge slot hour to '9':

If you have any ideas, they'd be very welcome!

I am also trying to use this to automatically track the discharge current with the energy use. Do you know what could be the issue? Have you figured out the syntax?
