How to apply Time Helper value to Time Entity

Configuration
1

Hi, I’m trying to automate something that I’m currently doing manually.

I have an inverter that’s integrated into HASS using Serial over TCP > RTU and I can manually set the ‘Charge Start’ and ‘Charge End’ times so that the battery charges during special free power sessions from my provider. The entities are both defined along the lines of ‘time.solis_s6_solis_time_charging_charge_start_slot_2’. These are shown on the left of the below screenshot.

I’ve created a set of time helpers as shown on the right of the screenshot and these will capture the date / start/finish time of the free power hour. What I want to do is get those times to automatically push across into the ‘Charge Start/End’ entities which I’ll automate to happen some short period before the session starts (I have other automations that need to have those slots left at 00:00 otherwise, so I can’t just normally fill the data directly to the entities days before).

I’m struggling to get the data from the helpers and into the entities on the left - anyone got any ideas? I can fill those entities in manually and then the data is pushed correctly through the RTU integration, but I can’t get it to populate using an automation.

Any help or guidance would be greatly appreciated!

If you can get the Hour/Minute values from your helpers, perhaps something like this might work for you; YAML block inside an automation:

data:
  value: ""{{ state_attr( 'YOUR-TIME-HELPER-ENTITY' ,'YOUR_VALUE' ) }}""
target:
  entity_id: number.solis_timed_charge_start_hours_2
action: number.set_value
