install VS tasmotizer

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.

If you use a d1 mini it has usb, just use https://github.com/tasmota/tasmotizer

Oh, that's sad. It seems like such low hanging fruit to support it. There is already a pull request to add the support that OP could use and test.

We start with a couple sensors for temperature, humidity, and particulates. Those connect to an ESP8266 via I2C and some proprietary IKEA protocol. That IKEA protocol wasn't in the default build, so I had to enable a define and rebuild. They've made very cool use of Gitpod so I didn't even have to install anything. I used Tazmotizer.py with a USB programming fixture I got off Amazon to load my custom firmware to the board.

It’s a SonOff Basic and flashed it with Tasmotizer. It didn’t work with the first try but after the third it works pretty well. I was too lazy to solder the pins on it. But if you have many of them, it would be great when you can upload it without a pc.

Incase you don't have a flasher,tasmotizer is an super easy software to flash a single bin file. https://github.com/tasmota/tasmotizer/releases/download/v.1.2/tasmotizer-1.2.exe

do i have to do the wiring and run Tasmotizer ?i assume not because the tasmota interface comes up just fine.

Tasmotizer is probably the easiest way to serial flash in Windows (and has cross platform versions for Mac and Linux). That said, it does require a hardwired serial connection.

Hands down easiest way is with Tasmotizer on Windows with a 3.3v FTDI. It's virtually plug and go.
