Having problems installing on Wemos D1 mini over USB

ESPHome
1

This is my first attempt with ESPHome. I’m trying to create a set of DS18B20 sensors to monitor my ASHP plate heat exchanger as per https://everythingsmarthome.co.uk/building-a-temperature-sensors-for-home-assistant-wemos-d1-mini-with-ds18b20-build-guide/
I get logs which always end ERROR 127. Do I have to copy the missing file to the project?

The first time it did much more, but I had the wrong board type.

So I removed lines from yaml file. The current compiled yaml is

So not sure what to try next.

Thanks for help

Sounds like the xtensa SDK is missing. Can check this issue for more info. Some people seem to have luck with reinstalling the add-on, someone else had to remove the .platformio folder. Can give it a try and see if any of the hints would solve your issue.

Why not

esp8266:
  board: wemos_d1

works perfect with my WeMos d1 Mini.

Yep, wrong board.

Thanks to @ckxsmart, @Kimotu, @nickrout for responding.

Regarding boards, I started again after watching another video about a temperature and humidity sensor. It is clear that HA is constantly changing because there used to be a drop-down list of boards to choose from. On a Windows PC rather than my iPad, there is floating help directing to the platformio.org site. Wemos D1 is now d1_mini rather than wemos_d1. nodemcuv2 is there and is how my boards were described on Amazon by AZ Delivery.

So while on the PC I setup a new device with the default yaml and changed the board to the nodemcuv2. I didn’t get far using the second option for install (it failed). The third couldn’t find the board on any usb port, so I have ordered a new micro usb cable. Other charging cables did make the blue led flash briefly so I suspect my first cable from an old Samsung phone is not suitable (micro a or b).

So then I tried the manual installation method which compiles everything. That had a fatal error quite quickly so I decided to reboot the Raspberry Pi in case the memory was low. This time it fully compiled a very long list of stuff and produced a binary. I just need to download it to the board :sunglasses:. It made me wonder whether some of the messages were to do with an incomplete compilation previously because my log posted above looks similar, if incomplete.

For now I will wait for the micro USB cable (delivery tomorrow) even though today I received some USB A to TTL devices to wire up. I’m kinda not sure how I will eventually set up the kit power wise. I don’t want the Raspberry Pi 3B in the hot water cylinder cupboard particularly. I do have an old charger with micro USB connector, and want to use Wifi. Battery is another option.

Hello

The micro USB cable has arrived. Plugged it in, the blue light briefly flashed and the install of software without the Dallas code for the DS18B20 thermometer worked. I see it on the network and can look at logs wirelessly. The yaml was just a completely standard New Device tweaked to change the board to nodemcuv2.

Now I must do some soldering of the headers so I can wire up the thermometers. I need to check the voltage pins first to make sure all is as it should be.

Thanks for all the help.
