NEWBIE: No discovery MQTT messages from Sonoff Zigbee Pro

[Sortova]

Apologies if this has been answered somewhere else, but I have spent a couple of days on this and I could use some help.

I have flashed Tasmota 15.4.0.3 (cd38f60-zbbrdgpro) onto a Sonoff Zigbee Bridge Pro. I can get various devices to join with the bridge and I have configured MQTT to talk with Home Assistant.

I set SetOption19 to off.

I can watch the MQTT messages coming in to Home Assistant, but the only "tasmota/discovery" messages I get are for the Zigbee bridge itself (tasmota/discovery/[HEX String]/config) and one for "Time" (tasmota/discovery/[HEX String]/sensors).

I do not see any messages for the various devices I have added to the bridge, but I do get other status messages just fine.

I've manually edited configuration.xml to add sensors to the MQTT configuration, and then they show up under the MQTT integration as entities, but it looks like I'm supposed to be able to get this to work automatically, at least from the various research I've done on the web. I've toggled SetOption19 to see if that will help, but it just generates the same two discovery messages above.

Am I missing something?

There is so much done "pre HASS" that the available information can get confusing.

Thanks in advance for any help and again my apologies if this is something obvious, but my Google-fu is failing me.

Well, you should not expect any discovery messages covering Zigbee end devices; these are not pre-defined to be known in advance. Hence the Tasmota Zigbee support (Z2T) is not doing anything there.

If you only want to use the Zigbee devices with Home Assistant, you might want to consider using the ZHA integration, which is also supported by Tasmota by providing a network tunnel to let ZHA take control over the Zigbee chip operation, instead of Tasmota handling anything Zigbee. Another approach could be using Zigbee2MQTT (Z2M) which I think is supported by HA, and again able to use the ser2net tunnel to take control over the CC2652 chip.

Still, it appears that this independent project using the Berry language is aiming to implement discovery support, if you set up schemas for it. I've not tried using it, and can't comment on how well it covers devices.

Thanks! Both ZHA and Zigbee2MQTT look like they are designed to be used with a dongle that you connect directly to the Home Assistant device. Do you have a URL describing how to set up the "network tunnel to ZHA"?

I don't have a lot of devices I plan to add, maybe eight in total. I've gotten the temp/humidity sensor working well, and I think the "human presence sensor" will also be easy (it sends JSON with a "1" when a person is detected and a "0" when it isn't, so setting it up like a switch should be simple). The weird one will be the push button, as I just want to generate events when the button is pressed.

Thanks again for your help.

This looks promising:

Yeah, you can use your existing Sonoff Zigbee Pro with ZHA or Z2M.

You are awesome. Switched the Sonoff to the TCP profile, uninstalled MQTT and Tasmota from HA, installed ZHA, pointed it to "socket://[IP address]:8888" and easy/peasy it just works. Thanks!
