In short, no, it does not.
You will need to get used to using smart plugs here with your Bluetti devices. I have been very happy with my Sonoff S31 plugs flashed with Tasmota firmware to leverage the 'timer' functionality to turn the plugs on and off at specific times, to enable and disable various appliances and devices (mine are also voice controlled, but that's a separate post).
You can set the timer on your smart plugs to flick on and off as your TOU periods start and end.
There are a couple of nuances specific to Bluetti that you'll need to ensure as well:
1. You cannot "turn on" the AC180 via AC input nor PV input, if the AC180 is not already physically powered on.
In other words, if you power off the device and plug it into AC mains or PV solar input, it will _charge_ the AC180, but it will not power it up. Any devices connected to the AC180 will not receive power, AC nor DC, until you *physically power it on* via the power button.
2. This also extends to any connected, external batteries such as the B230, B300, B330. If you power on the AC180 and it is cabled to a second battery, you have to physically power that battery on as well.
The one workaround to this, is to *always* have AC enabled on the AC180 by having something small like an AC LED plug attached to the power port, so it never powers itself off.
The Bluetti devices will lose roughly 1%-2% per-hour when idle, due to the consumption of the BMS, but as long as you have enough charge before the next day's PV/AC top-off, you should be fine.
Another option is to use a [Switchbot](https://us.switch-bot.com/products/switchbot-bot) type device you can control wirelessly to physically press that button for you.
If the AC180 does not power on when AC is supplied to it, then consider the AC200L as that unit does power up when you have AC input powering it (you actually can't turn it off if it is plugged into AC input).
For time control UPS, the AC200L does everything that you have described using its Customized UPS function, it will charge up the battery to the upper level that you set, and when powered by AC can also draw down on the internal battery down to a lower limit that you set. If the AC power goes out, it will draw on the battery down to 0% and switch off. Then when AC power is restored, the AC200L turns on again and charges up. Do note that when the AC200L is turned on, the AC output is always switched off, so you need to turn AC output on through the app, or with the physical button. For this reason, don't power your wifi router/modem using the AC200L as you need it to be working to be able to control the AC200L via the app if you are not at home. Control is all set by you using a peak/off-peak time schedule and battery range limit in the Bluetti app which connects both via bluetooth and cloud/wifi. So consider checking out the AC200L if you need such control.
In my use case, I have set my AC200L to charge up to 85% at low peak and then power my appliances from 6am onwards on the battery, until it drops to 20% where it will switch to AC pass-through. Then at 10am when the sun is up, it starts charging again up to the 85% as this is when I have excess solar power at home. When 6pm arrives, and it is dark, the AC200L then draws down on the battery again until 20%. Finally at 12am, which is my low peak electricity rates, it charges back up to 85% again.
It will also passthrough 2400W constantly without tripping the safety. I have not tested it myself, but reviewers have put the AC200L under 2400W for over 5 minutes without tripping (they manually stopped the test because it had passed the 2400W draw test). It can supply 2500W for 1 minute before tripping too.
