Tasmota devices not working

Configuration
1

Just after the last update came out I was on holiday, so did not apply it until yesterday. When it got dark I went to turn on the lights in one room and they did not work.

Turns out that I can no longer control any tasmota device from within HA. I can happily control them from their own Web page (and from within TasmoAdmin) none of them are available in HA. Any ideas what happened and how I can put it right? I’ve tried updating firmware on a couple of devices incase the older one was causing the issue but they still stay unavailable.

Have you given the whole thing a restart just to make sure you are starting from a level playing field?

Hi Trevor Baxter,

I would go here and reboot the host… Check that the config check passes first just in case.

Open your Home Assistant instance and show hardware information.

Yep, first thing I did (I work in IT ;-))

It is really weird they just do not seem to want to connect.

In the Tasmota Webconsole, try

setoption19 0

if that does not work, show the Tasmota logs for one (from the Webconsole)

It seems to be a login issue with tasmota not being able to connect to the MQTT server and I cannot work out why.

It had an MQTT username and password set, but I can find no reference to those on the HA server. It may be something set up all those years ago that just got depreciated?

I have tried setting up a new HomeAssistant person for logging in to it. I verified that by re-configuring the MQTT integration using this new name and password. Still though the console is reporting connect fail when I put these new values in Tasmota.

What version of Tasmota are they on ?

Hi Trevor Baxter,

Look in the MQTT Addon config for a password and login.

Thank you all working now. The challenge was that it could not route to the MQTT router. Once that was fixed it started to work correctly :slight_smile: Thanks for all the help.
