install VS templates

The middle board looks like you might be able to use the browser based Tasmota installer https://tasmota.github.io/install/ to flash and use however you like. I'm not sure what the config would be after you flash it, though.

Web Installer is up. https://tasmota.github.io/install/.

Its not no soldering but it is low effort soldering. Pulling from a couple guides here.

Tasmota is local first.

Get a wemos D1 and a https://www.ikea.com/us/en/p/vindriktning-air-quality-sensor...

https://tasmota.github.io/install/ flash the unofficial all sensors build.

https://github.com/Hypfer/esp8266-vindriktning-particle-sens... Solder as follows GND to GND on ESP, 5V to 5V on ESP and finally the last one to D2 on the ESP.

Guides I am stealing from. https://github.com/Hypfer/esp8266-vindriktning-particle-sens... Has most of the hardware side. But its using a different software.

https://blakadder.com/vindriktning-tasmota/ is where I got most of the rest of the info but he uses a separate voltage regulator. If you use the Wemos D1 Mini you should not need that.

After that the internet has plenty of info for hooking tasmota and say home assistant together.

Tasmotizer or the Tasmota Web Installer are another couple easy-mode installers. Tasmotizer requires installation, but will allow you to upload a custom bin; not just Tasmota bins. The Tasmota Web Installer doesn't require install, but getting to HAAA will be a two step process: You'll have to upload Tasmota first, then reflash to HAAA.

I use this USB to TTL adapter, but there are tons in the ~$5-10 range that work. I'd stick to genuine FT232RL or CH340G based ones though. Most of the time, you don't even need software anymore, as you can flash straight from Chrome now.

Setting two on/off cycles with 50 discrete schedules seems like a very inefficient way of doing this when the same thing could be accomplished with two rules. Any compatible device flashed with Tasmota or similar FOSS firmware would make this possible.

Have a look at https://templates.blakadder.com

Another WiFi based option is any compatible smart relay or switch flashed with Tasmota. In Tasmota, SwitchMode 15 decouples the switch state from the relay and sends status changes via MQTT to HA.

2) If you want to switch on/off the light switch in your room, your best bet is to replace your regular light switch with a WiFi light switch. (Yes, you must have some electrical knowledge to do this. But trust me, this is best, most reliable way.) See https://templates.blakadder.com/ for some good devices. Many of them can be re-flashed, so instead of using "their app", the light switch can be a web server that you can talk to from any computer on your network (including your laptop, your phone, etc).

If you're familiar programming ESP boards take a look at this repository of compatible devices.

Wifi switch, I suggest one that runs tasmota. Blakadder website seems to help.

I cannot find the correct model for this plug. On the back it says "WiFi Smart Plug / TWSP017" but I cannot find any reference to this online. I looked at the (long) list of pictures of plugs and sockets at the templates.blakadder.com site, but without finding anything that looks quite like it. There is one power socket, one LED (that never seems to be lit) and one button on the left side. It is a square shape with rounded corners; too generic a description to be useful I'm afraid.

You mention incompatibilities. I am not 100% what you mean but here's a link of Zigbee2Mqtt supported devices and Heres a list of tasmota supported devices . i'd reference these before buying anything.
