#Tasmota, MQTT, HomeAssistant and Auto Discovery

I've recently gotten myself a Sonoff Zigbee Bridge Pro, onto which I've flashed Tasmota. I've set up an MQTT broker and manually configured a ZigBee switch in configuration.yml which I now can control from HA by publishing a message from the WebUI to topic cmnd/tasmota_6C8778/ZbSend with payload {"Device":"0x0F0D","Send":{"Power":1}}.

However, I have a feeling that using ZbSend for this is wrong. I would expect publishing to e.g. cmnd/switch1/Power with payload ON, but that's just my feeling.

Additionally, it seems that the "autodiscovery" is not working at all. I have several Zigbee devices connected to Tasmota, but none appear in the HA UI. I haven't added any specific config related to this, AFAIK.

Thanks in advance!

You'd be a world better off using ZHA or Zigbee2MQTT, though that ZBBridge Pro is generally not great and a proper coordinator would be better

@vital ruin

  • What is a proper coordinator in your opinion?
  • Where does Zigbee2MQTT run?

  1. See the pins in #zigbee-archived - Tube or SMLight (or a great many other things, other than Sonoff)
  2. On the same host as HA, if you want

Thanks

Do you have any example messages for how data is sent and retrieved with Zigbee2MQTT? I am interested in the format

vital ruin
#

Well, other than their own docs?

#

They cover it pretty well, it's all (just) JSON payloads on the broker - kinda similar to Tasmota

#

Of course, they also have fully working MQTT Discovery for HA, so you don't have to care about the fact that it's MQTT

molten dragon
#

Anyway, I am trying to avoid jumping ship. I've invested in some hardware already and it'd be great to have it working. I am just trying to figure out if I'm doing things the right way, and if someone can point me to some articles or docs that I haven't stumbled upon yet.

#

Would you also mind explaining what is meant with "auto discovery" or "MQTT discovery"? To my understanding, any devices connected to my Tasmota device should pop up in HA - and they don't.

vital ruin
#

Right, but that discovery only applies to the Tasmota devices themselves

vital ruin
#

If you want simplest to set up, then ZHA is the way

#

If you want MQTT then Zigbee2MQTT is the way

Additionally, what should I expect when I run ZHA? How well will devices function?

For instance, right now I have no clue what payloads to send to some of the devices via MQTT. Is there some way to ask the device what capabilities it has?

vital ruin
#

If you want to know about Tasmota, you should join their Discord and ask them

#

Though, with HA you've got zero need to hand craft those payloads

vital ruin
#

If so you've got bigger problems than that

Then ... you have bigger problems

#

If you honestly expect to be the target of APT then you need more help than we can give 😉

#

Nobody else is gonna give a shit about trying to break your Zigbee setup

#

And, frankly, even they won't

#

Also, if you're really that worried, I hope you're using TLS/SSL everywhere, and not using self signed certs

#

And otherwise adopted zero trust

molten dragon
#

Just because it is unlikely doesn't make it an unreal threat. I prefer security and want to rely on unauthenticated serial connections over LAN

vital ruin
#

Then you need to use a USB based coordinator

molten dragon
#

:/

#

I will see what I can find through Tasmota communication channels
