Migrating Zwave & ZigBee stuff to MQTT - guidance needed.

Next device I'm hoping to try out: a Xiaomi button.

The above has similarities with the Hue dimmer switch

And then there is the magic cube - that's a very interesting one. eg you can just rotate it to dim/undim lights. Flip it and control something else.

akbooer

Thanks for the report… all exactly as I would expect. Indeed I had not done anything about initialisation apart from the bridge/device message. I now need to use the variables from existing devices to build the initial table.

I see what you mean about the error message. Will fix that. Will post separately on the debug switch. It may make sense to have console page for that.

akbooer

@a-lurker

Latest testing version v22.12.01 should fix all reported issues.

I'm working on the switches. These will appear as scene controllers.

@a-lurker

Just pushed v22.12.01b with initial go at supporting those switches.

Light bulb slider now working:

Issue with variable updating. Looks like api.lua handles this somehow in the meta verse:

openLuup.context_switch::  ERROR: [dev #0] ./openLuup/L_Zigbee2MQTTBridge.lua:166: ERROR - READONLY: attempt to create index illuminance

So added some debug code to this section - not sure how variable "S" is used:

  -- update exposed values
  local S = D.exposes
  for n,v in pairs (message) do
    D[n] = tostring(v)
  end

Motion sensor:

luup_log:0: D: table: 0x1b25f70
luup_log:0: S: table: 0x1680730
luup_log:0: n: illuminance

luup_log:0: n: device_temperature

Ooops!

Looks like this should be:

    S[n] = tostring(v)

@a-lurker

” Looks like api.lua handles this somehow in the meta verse:”

Yes, FYI the new openLuup API maps device services and variables directly into the plug-in context. There are shorthand names for the otherwise unwieldy serviceIds:

API[devNo][serviceId][varname] = value    -- sets the value
value = API[devNo][serviceId][varname]    -- gets the value

These are all standard Lua (metatable) structures, so you can write:

D = API[devNo]    -- the device
S = D[serviceId]    -- the service
S[varname] = value    -- sets the value
value = S[varname]    -- gets the value

kWh = D.energy.KWH    -- get device energy usage

It’s still evolving, but this much is stable. It’s so neat and readable compared to the usual luup.variable_set/get() calls, and I’m now using it all the time in new code development (since I’ll never be writing another Vera-compatible plug-in.)

akbooer

@a-lurker

Switching to the development branch for updates...

new v22.12.5 should update those table variables now (and fix the typo.)

@akbooer
This is all going nicely - but time will tell how reliable the system as whole would be. Have added in one of these Aqara buttons and it work fine.

Zigbee2mqtt "interviews" a device while it's being paired. On occasion the interview is partially completed ie it fails and some variables are void or invalid but "Interview completed" is still set to true.

With such a faulty pairing and with openLuup being subjected to same, more often or not, the function "infer_device_type" will default to "D_GenericZigbeeDevice.xml", of which the actual file doesn't seem to exist. So one occasion I observed this error, which appears to be related:

openLuup.context_switch::  ERROR: [dev #0] ./openLuup/L_Zigbee2MQTTBridge.lua:438: attempt to call field '?' (a nil value)
openLuup.mqtt:: ERROR publishing application message for mqtt:zigbee2mqtt/0x00158d000706951c : ./openLuup/L_Zigbee2MQTTBridge.lua:438: attempt to call field '?' (a nil value)

You have to repair the device, delete the "Generic" device in AltUI and then restart the zigbee2mqtt server to get the correct device to show in AltUI.

Inference: Looking at the function "infer_device_type: the code IMO should be split, so "switch" and "action" produce different devices ie an on/off switch or a scene controller:

In GitHub: elseif exp.switch or exp.action then

The nomenclature is bit tricky: switch is often conflated with power relay switches and say a scene controller switch. In Zigbee2MQTT speak, a "switch" is like a relay (mechanical or solid state) and a scene controller switch is considered something that has an "action".

Composite devices will become an issue and hopefully that can be handled in the future (yes can of worms), especially dual outlet power sockets or multi gang switches, which are ubiquitous.

Here is an example of sometime that doesn't fit the mold. These Aqara devices logically act as both a switch and a scene controller. Question arises if you do say a "double" click, what happens to the switch status. Likewise for say "hold_release". There are very few of these devices and they are nearly all made by Xiaomi.

Is there some symptomatic problem I should know about?

@a-lurker said in Migrating Zwave & ZigBee stuff to MQTT - guidance needed.:

"D_GenericZigbeeDevice.xml", of which the actual file doesn't seem to exist

It does, in openLuup's virtual world. If you try http://openLuupIP:3480/D_GenericZigbeeDevice.xml you should see this in the browser:

<?xml version="1.0"?>
<root xmlns="urn:schemas-upnp-org:device-1-0">
 <specVersion>
  <major>1</major>
  <minor>0</minor>
  <minimus>auto-generated</minimus></specVersion>
 <device>
  <staticJson>D_GenericZigbeeDevice.json</staticJson>
  <deviceType>GenericZigbeeDevice</deviceType></device></root>

I'll fix the error and review the infer_device_type() function. It was always going to evolve anyway as different device needs arise.

I have tended to represent any sort of multi-action switch as a scene controller. There will always be difficult cases (sometimes resolved by using vendor/manufacturer) but I have shied away from an extensive configuration database. Plausible, I suppose, to pull this from the web...?

I rely on Philips Hue for the few Zigbee devices that I have, so probably won't get to road test this for myself. You're going to want to do the whole thing again for Zwave JS ?

@akbooer said in Migrating Zwave & ZigBee stuff to MQTT - guidance needed.:

I don't think so but who wants to set up heaps of devices in a new set up when everything has been going well for years with just openLuup and an old Vera war horse!

Plausible, I suppose, to pull this from the web...?

Don't need to get to complicated too soon, as you just about have it all covered but I'm still thinking of one of these Hue Smart plugs. It's just a switch, as opposed to a scene controller.

I rely on Philips Hue for the few Zigbee devices that I have

Arrhh you know you want to ditch that hub.

You're going to want to do the whole thing again for Zwave JS ?

Maybe after a cup of tea and good lie down. And yourself?

Definitely the tea. Possibly the lie down.

You'll have to educate me about the protocol, yet again, but it should almost be a dead-ringer for the Zigbee ??

Release development v22.12.6 separating switch and controller devices, and fixing nil function pointer.

Thanks for that - looks OK now.

Have now got all my Hue stuff running with no Hue hub - that's good. A few complications here and there.

Main complication:
Conditions:
z2m is running and openLuup is running.
Then pair new device: in this case this Philips light bulb with z2m.
z2m logs this to the terminal. I've prettied the json section so you can read it:

Looks like openLuup then responds to the topic zigbee2mqtt/bridge/event ?? and creates a Generic device. The openLuup log doesn't make it clear what topic it's responding to when it creates a device but you can see in the log that it has found a new device:

So it looks as the event returns the same data as "zigbee2mqtt/bridge/devices" does, as each new device is paired but it's parent json is a little different. The device definition is below "data" in the json:

"data":

With type set as follows:

type="device_interview",

and this must indicate success:

data.status ="successful"

Hope that's clear - bit hard to explain.

Suffice to say I added a pile of stuff and ended up with a whole pile of generic devices, which I had to remove one by one with a openLuup restart for each. Got a bit ambitious!

However; it looks like the ability to handle the addition of new devices on the fly without having to restart thez2m server each time to get the device definitions, would certainly be possible and a welcome addition.

Looks like you just look for the event topic with {"type":"device_interview" and {"data": status":"successful".

The json contains definition.expose.type = light so the function infer_device_type() should still do its work OK as it currently does.

I can't test any new code on this as I have now added all my devices. Although I could unpair just a light bulb and repair it and see what happens.

a-lurker

A slight in convenience:

Conditions:
Having just added a scene controller to z2m and restarted the z2m server and openLuup has dutifully added it in and here it is:

Great; so first thing to do next, is to link the scene controller to a scene: So create a new scene, dial up the scene controller and put a watch on to create a trigger:

LastSceneTime	(new~=old)

Problem is LastSceneTime is nowhere to be found - bit disconcerting at this point. In order to proceed, you have to push a button on the scene controller to get the variable to be created. Suggest the variable is created when the scene controller is first added to openLuup and set its time to Unix year zero.

a-lurker

A slight in convenience: no way to set color on the light bulbs. X,Y color space seems better than RGB as it allows you to specify white color temperature.

a-lurker

This vibration detection device and other similar devices should be "inferred" as a motion sensor. They expose "contact".

Perhaps infer_device_type() could use some look up table or look at json string that could perhaps be later saved to a file that the user could fiddle with? eg some vague pesudo code. Whatever you figure would work.

local deviceType = nil
if (lookup.exposes.contact) then
    deviceType = lookup.exposes.contact
end

akbooer

@a-lurker said in Migrating Zwave & ZigBee stuff to MQTT - guidance needed.:

Looks like openLuup then responds to the topic zigbee2mqtt/bridge/event ?? and creates a Generic device.

Can't see how that would happen. The bridge code is clear that anything other than bridge/devices is ignored:

local function handle_bridge_topics (topic, message)
  local subtopic = topic: match "^bridge/(.+)"
  if subtopic: match "^devices" then
    create_devices (message)
  else
    ignore_topic (topic)
  end
end

and it should write Topic ignored... in the log. If it creates a device, it must be receiving the actual /devices topics. I take it that your "info" log messages are your own additions to the code. I could certainly make it respond to a /event topic. The Shelly and Tasmota bridges already create new devices on the fly, because they send their own configurations when they connect to MQTT.

Yes, that's true. The root cause is actually that the service file for a scene controller S_SceneController1.xml does not contain a definition of that variable, or a default vaule for it. I could force this at device creation, but you have found a work-around alreay.

Some investigation required here. The existing Color service definition defines three actions of interest:

setColor
setColorRGB
setColorTemperature

It's not clear from the service file definition what the possible value/syntax is for any of these commands, so that would mean delving into the UPnP documentation, which, previously, I've found to be an absolute nightmare (as are most international standard definitions.) Perhaps csomeone here can aleady tell us the answer?
