Development
1

Somewhere down the upgrade from 0.46 to 0.49.1 i lost the EDIMAX plug, the plug works fine with EDIMAX own app
IP, username and password is set correct, is it just me or a general fail in EDIMAC component?

Which plugs do you have, I am on 49.0 with no issues.

3

model is SP-1101w, FW 2.04

4

Interesting, do they ever connect? Or are they connecting and dropping?

Double check all the settings in your config is about all the troubleshooting I can offer. I’m no good at reading the error logs most of the time.

I have the same issue.
Since firmware upgrade to version 2.04 hass.io can’t connect to my Edimax SmartPlugs SP-1101W switches.
Error messages found as follows:

What could be the reason? From the EdiLife App I can access the devices. PW doublechecked.

HASS config:

core-ssh:/config# cat switches.yaml
### switches.yaml
- platform: edimax
  host: 192.168.133.119
  username: !secret switch_edimax_user
  password: !secret switch_edimax_password
  name: edimax1
- platform: edimax
  host: edimax2
  username: !secret switch_edimax_user
  password: !secret switch_edimax_password
  name: edimax2
- platform: edimax
  host: edimax3
  username: !secret switch_edimax_user
  password: !secret switch_edimax_password
  name: edimax3

Before the firmware update, the switches worked without problem.

They have changed their api from basic auth to digest auth so the current code in home assistant is no longer compatible. Hopefully someone will change it soon. The new python code needed to control the switches can be found here

I assume no volunteers yet to fix this issue?

FYI This is now fixed in version 0.65, see the release notes and here:


Unfortunately the new edimax fw 2.04 doesn’t allow the plug to be discovered in the Edismart app (for me at least) so I can’t control them via Alexa. Can’t have everything I guess.

I’m getting similar error messages with version 0.65.6 and plug firmware 2.08.

Did the update to 0.65 help you?

UPDATE:
Solved by removing pyedimax directories: /srv/homeassistant/lib/python3.5/site-packages/pyedimax* and restarting HA.
