Not really. That is one thing I have no need to automate. We rarely change our blinds. They are almost always open.
If it was super cheap, like $10 per window I would just because why not.
But the cost for what it provides is probably some of the worst ROI in the HA space.
It is much cheaper because you are getting a fraction of the capacity. The one you linked has 3 kWh of capacity. The power wall has 13.5.
The power wall also has a 6 kW inverter instead of 3 (and I seriously doubt it will output 3 continuously without overheating).
Plus you are not connecting these things to your home breaker panel like the powerwall does.
I'm not a Tesla fan, but you have to compare apples-to-apples.
Just break it. It is garbage anyway.
It could be many things.
Does the switch work locally? Can you hit the button on it and make it turn on?
Are you sure the load is good? Have you tried it with another load or validated the load works without the switch?
Did SmartThings find, recognize and add the switch?
Is the switch still within range of your z-wave network?
What would be my best option to get a smart switch on this that would run my electrical outlets in the eves?
A smart switch is a good option since the outlets are already wired to the switch. It should work.
The other option are smart outlet plugs. The problem is these can't do anything if somebody turns of the switch.
What you need are smart thermostats. It sounds like the hard part will be finding smart thermostats that work with your particular units.
Scene controller?
the wiring is 12VDC
Ugh, nevermind. Maybe you can find a 12v presence sensor.
It will. But this is a problem you created. Should not have been buying WiFi devices.
I preach this to anyone who will listen here. Buy devices that use low-latency mesh networks. WiFi was not designed for turning lights on and off. Zigbee/Zwave/Matter were.
WiFi is for high-bandwidth, high-latency devices. Your computer, phone, TV, etc...
Home automation devices should be on a low-bandwidth, low-latency network like the popular mesh networks I mentioned above.
The safest way would be to have a SwitchBot press the existing buttons. But the existing buttons are part of your problem.
What does it control? Is it a proper AC with compressor or just a fancy fan?
If this is a thermostat controlling a compressor you don't want to go replacing it with just relays or it will be very easy to kill your compressor.
But you could program and ESP board as a thermostat to do it for you. ESPHome has some off-the-shelf libraries for this.
If it is just a fan, a relay would allow you to turn it on an off. But you still probably won't be able to change speed because it probably does PWD to control fan speed. This could also be solved with an ESP running motor controller code.
Show me how to control an HDMI matrix and multi-channel amp through Alexa or similar consumer controller.
If you want to DIY AV distribution you probably need Home Assistant, very specific hardware it support and a lot of time to learn how. With Control4 you just plug in the hardware, tell it which channels are wire to which rooms and you are done.
Not great advice considering these could easily burn your entire house to the ground if not done properly.
Most people do not have the knowledge and skills to even begin to attempt this.
I have built many LiIon battery packs and it is not a huge savings over buying pre-built packs from professionals. The cells are going to be the primary cost no matter what. Then you still need to get an inverter and charge controller and package it all nicely.
These things are intended for people who like the convenience. Telling them to build their own is equivalent to telling my parents that Ring doorbell is overpriced and they should roll their own solution. You know, bu ya DVR, buy compatible cameras, connect it all and securely exposing it online. Easy right?
