plug won't connect to wi-fi network after update
Opened this issue · 2 comments
Hello,
I am having an issue after trying to update the firmware of the plug to the latest version of the repository. Now the plug is not connecting the the wi-fi network and is does not appear to respond to the button to turn it on/off. It also appears to not be responding to me holding the button for 30s for it to forget the wifi credentials as I can't see any AP from it (checked with WIFI analyzer on android phone). For reference I have used the plug for several months with no apparent issue, so the hardware should be mostly OK.
The updated kauf-plug.yaml
is what is the current latest commit on the repo (commit 2973da17141afefd2ccaa19c21021d209de596b0
) and I only changed the name and wifi connections as follows:
diff kauf-plug.yaml kauf-plug-f6e9b1___new.yaml

< name: kauf-plug # **** CHANGE DEVICE NAME TO SOMETHING UNIQUE PER DEVICE. RENAME YAML FILE TO SAME NAME. ****
< # **** USE DASHES (-) INSTEAD OF SPACES OR UNDERSCORE (_). USE ONLY LOWER CASE LETTERS. ****
< friendly_name: Kauf Plug # **** CHANGE FRIENDLY NAME TO SOMETHING UNIQUE PER DEVICE ****

I've built the updated firmware file using ESPHome v2023.6.3 (which I think is the latest, or at least a recent version) on a RPi4 (which I think should not matter) with no apparent issue.
After building the fw file and compressing it with tar.gz (down to 361378 bytes, so it should be OK for an OTA update) I performed the OTA update and the device page said it was successful. As I mentioned right now I have a plug that is not connecting to a wifi network, red LED is dimly on and is not responding the the button.
I'd like for some help to fix / un-brick the device so I could continue using it.
Let me know if I was unlucky or if I did something wrong, and I am looking forward for some help.
p.s.: I will attach the "backup" and the "new" versions of the yaml configurations for the device that I used for reference. Let me know if me uploading the actual FW binary would help as well.
The top plug is the one with the issue (it uses the kauf-plug-f6e9b1___new.yaml
configuration), the bottom one is using a configuration very similar (except the unique names) to the old configuration that I've attached (the kauf-plug-f6e9b1___backup.yaml
configuration)

Probably something went wrong with the flash. Did the same thing work on other plugs? If you send me an email I'll send a replacement. brian@kaufha.com
Hey @bkaufx, I didn't try flashing another plug after the first one I tried failed.
I recently saw a review of the product that mentioned this:
If you need to update your firmware for any reason, like esphome updating or needing to tweak any settings, you MUST flash their minimal firmware before flashing your real firmware because there is not enough space accept it ota (...)
I didn't have to do this when I first bought the product and when I did a first upgrade afterwards (my comment here was my 2nd upgrade of the configuration).
Do you think the procedure of flashing the kauf-plug-minimal.yaml
before trying to flash the kauf-plug.yaml
could help in future upgrades? If so maybe it would be a good idea to add this information on the repository documentation.
I will send an e-mail for a replacement unit shortly. Thanks for your attention
