I can ask the LLM to turn on a helper group of switches and it will turn them on and then ask it to turn off the same helper group and it cannot find it. These.. inconsistencies, can change with every HA update or change when I do a restart of HA. The inconsistencies are different whether the entire HA server has been restarted or just HA.
Also, consider HAs general acceptance will never happen as long as the administration of HA takes more time than saved by having home automation. I think you realize this and are trying to improve that. But with as much as needs to be done in this area, it's going to be quite a while before you get there. Decade+
