Zigbee2Tasmota

[dgrostoto]

Well, zigbee2tasmota (Z2T) running on a sonoff Zigbee bridge has several advantages :
- Better emission/reception : the sonoff can be located anywhere in a location that can be better for zigbee reception, in particular far from USB3 port from the raspberry (interference in the 2.4Ghz ISM band), and closer to endpoint Zigbee devices (more centralized)
- Better emission/reception : the sonoff is designed to reduce interference between its internal wifi and zigbee transceiver
- The sonoff can handle far more devices (more than 100 i think) than the CC2531 (less than 20) can. Altough there is other dongles that can handle that much (check zigbee2mqtt project for details)
-line of sight is 80meters on sonoff vs 30meters approx on CC2531 (same remark for other dongles as above)
- the sonoff can handle local rules and the soft is very reliable (the tasmota software is one of the best quality software i've ever seen) without using central program such as domoticz / jeedom / openHAB / Home Assistant that may have bugs (sorry for all developers of this programs i'm telling this from a industrial production point of view, which is important to me), these local rules perfectly fit simple tasks and are very fast to execute.

Zigbee2tamosta support in domoticz would be a great feature. It's s shame that the zigpy library could not be integrated which may be a good way to integrate zigbee within domoticz. I saw the discussion about an obscure crash related to sqlite3 usage, maybe i'll take a look closer to see if i can think about a elegant solution about dynamic /static linking against the sqlite3 library.

Note about using rules on tasmota to modify payloads to get them work on domoticz : this is really a bad way to go, because number and size of rules is very limited (ESP8266 have little memory). Rules should be used for other tasks such as extending the the direct associations permitted by zigbee for example. Node-Red can be a workaround (transforming MQTT message) but quite heavy for the job.

My first steps with the Sonoff Zigbee Bridge.

I managed to pair 4 sensors.
I've read industrial stability can be done with RULES, but I would appreciate if these devices could appear in my Domoticz interface.
Any suggestions on how to do that?

I've Node-Red where I could do something like this to maybe virtual devices in Domoticz ??

You can use rules to inform Domoticz about the updates. For example:

Rule1 ON ZbReceived#0x0003#Power=1 DO publish domoticz/in {"idx":152, "nvalue":1} ENDON
Rule1 + ON ZbReceived#0x0003#Power=0 DO publish domoticz/in {"idx":152, "nvalue":0} ENDON
Rule1 1

These lines sends the 0x0003 device's actual state to domoticz and activate the rule (Rule1 1).

From Domoticz, you can create a nodered flow for domoticz/out mqtt with a function like this (dont forget to add RBE to the flow to prevent loops):

var payload = msg.payload;
msg.payload=JSON.parse(payload);
if (msg.payload.idx == "152") {
msg.topic = 'cmnd/tasmota_DC02EC/ZbSend';
if (msg.payload.nvalue == "0") {
msg.payload = "{\"Device\":\"IKEA_socket\",\"Send\":{\"power\":\"off\"}}";
} else {
msg.payload = "{\"Device\":\"IKEA_socket\",\"Send\":{\"power\":\"on\"}}";
}
return msg;
}
return null;

Probably there are much easier solutions but this is just working for me (I used friendly name in nodered, not 0x0003 but those are the same devices)

Nice addition indeed.
Had noticed the rules somewhere else but with your explanation is just makes more sense to me.

Thanks for sharing.
A native integration would even be better

Hi, i am looking to implement my domoticz installation with zigbee devices, and found Z2T with a Sonoff zigbee bridge pro which runs with a esp32 and can manage 128 values.
the good news is it is cheap and easy to flash with tasmota
the bad news is i can't find the way to link with domoticz, except with the Tasmota rules to read sensors values , and no solution to command device from Domoticz thru mqtt to Tasmota and zigbee device.

Did anybody go further than that ?

Have a look at this thread.
I do not use the pro, but it is tasmota. Maybe you can use the same bodered flow to connect it to domoticz and not use the rules in tasmota

It is still much easier to integrate a Sonoff 3.0 usb Dongle, 30 euro. No need to flash and plug and play with zigbeeforDomoticz plugin or zigbee2mqtt with MQTT Autodiscover.

[hoeby]

Waltervl has a great point there.
If you don't need the wifi option on the zigbee coördinator, choose an option which is default supported, much easier.

If not, the nodered flow could be an option.
Not that many devices integrated by default, but you could add them in the flow

Thank you for your answers
I ordered a sonoff USB key with a button, a door sensor and a temperature device.
Now i just wonder how i will integrate this usb key on my DS718+ with DSM7, as i have already a RFX433 dongle plugged on it.. How does it manage several usb dongles? on which logical port ?

Does the NAS have multiple USB ports? Else you have to buy a USB HUB. they seem to be a little bit picky on brand/type see eg https://community.synology.com/enu/forum/1/post/129133

[Sherco49]

Do you talk about logical ports, or physical ?
The 718 has 3 physical ports, but i wonder how a sonoff dongle will be recognized and which device will i have to set up in zigbee2mqtt as i have already the RFX433 plugged on ttyusb0

[waltervl]

Then I suppose it will be in ttyusb1 or ttyusb2. Did you plug it in and check? I do not know Synology NAS but there probably is some way or command to tell what devices are connected to what port.

[Sherco49]

As i didn't received the Sonoff dongle yet, i can't say now, but your answer makes sense, and i hope it will works like that.

[Sherco49]

Well, i have received the sonoff usb 3.0 dongle.... No way to install it with zigbee2mqtt, it is recognized with the lsusb command, but no way to link it with a serial port like ttyACM0 or ttyUSB0....
i tried lots of drivers cp210x.ko, some are for DSM 7.0 (i am on DSM 7.1), and the 7.1 driver doesn't want to insert (invalid format).
Whatever way i go, there is always an issue to complete.
My knowledge look insufficient for this, synology dsm doesn't help at all.
I have to consider the bridge with lan connection, maybe it is more reliable...

So I was just wondering Zigbee2Tasmota project now has lot's of devices working with Node-Red to Domoticz.
However I wanted to check out Zigbee2MQTT as described as other solution (better support out of the box).

Anyone a clue on how to migrate th Zigbee2Tasmota 64bit LOW and 64bit HIGH key into Zigbee2MQTT ?
If my info is correct zigbee2mqtt should continue where Zigbee2Tasmota was "left" off.

Any other case would require me to setup the whole network again and that would be a pitty.
