Internal matter - Τασμώτα (2023)

The protocol in question is highly experimental.

Matter is only compatible with ESP32x based devices and requires a specific version of s#define USE_MATTER_DEVICE

Implementation notes follow for understanding and expanding the material.

The pluggable system is designed to have different implementations for different types of devices or sensors. Each Matter endpoint manages an instance of the plugin class.

O'clockroot(0) drivetema.Plugin_Rootclass because of their special behavior.

We currently offer the following courses:

Klasa pluggable Description

function_updated(endpoint, cluster, function, fabric_specific) Point out that a feature has changed and pass on any active subscriptions.
extender_process_attributes(ctx, cb) Go to attribute extension (used for read/write/subscribe attribute)
It is only called when an extension is needed, so we don't have to report errors because they are ignored.

callscb(pi, ctx, direct)for each extended feature.
Pi: The plugin instance to which the attribute is directed (via a trailing dot). Note: Nothing is sent if the attribute is not declared in the plugin's supported attributes.
ctx: environment object withfinal point,complex,Feature(Yeahmandate)
directly:he saysif the function is directed directly,falselyif specified as part with wildcards
returns:he saysif processed successfully,falselyif an error occurred. Yeahdirectly, an error is returned to the caller, but if expanded, the error is silently ignored and the attribute is ignored.
in case yesdirectlybut the endpoint/cluster/feature is not supported, callscb(nula, ctx, istina)so you have a chance to code the correct error (UNSUPPORTED_ENDPOINT / UNSUPPORTED_CLUSTER / UNSUPPORTED_ATTRIBUTE / UNREPORTABLE_ATTRIBUTE)

invoke_request(sesija, val, ctx) Manage theme plugins
Plugins allow you to specify responses to read/write attributes and command calls

It implements TLV encoding and decoding as defined in Appendix A of the Matter specification. TLV stands for Tag Length Value Encoding. It is a way of encoding labeled values ​​and structures in a compact binary form. Most Matter messages are TLV-encoded.

Analysis and impression:m = matter.TLV.parse(b) print(m)

TLV Types~

Advice Description
I1 I2 I4 A signed integer up to (1/2/4) bytes (as a 32-bit Berry-style signature)

i8 u8 Signed/unsigned 8 bytes. you can passproblem (8),int64()heAnd t. The type is collapsed to a lower type if possible during encoding.
bik boolean takehe saysifalsely. remove the insideSHE IS RIGHTierrorthat you don't need to use
FLOAT 32 bite float

B1 B2 thickbyte(), the size is automatically encoded as 1 or 2 bytes
NULA take onlynulavalor

Create a TLV~

simple price:subject.TLV.create_TLV(type, value)

Example:materia.TLV.create_TLV(materia.TLV.UTF1, "Hello world") materia.TLV.create_TLV(materia.TLV.BOOL, true) material.TLV.create_TLV(material.TLV.NULL, μηδέν) materia.TLV.create_TLV(materia.TLV.FLOAT, 3.5) materia.TLV.create_TLV(materia.TLV.I2, -345) materia.TLV.create_TLV(materia.TLV.U8, bytes("DEADBEEFDEADBEEF"))

When the subscription is issued by the initiator, we create a copy of itsubject.IM_Subscriptionwho owns:

  • HeCASE sessionto which the subscription was issued. If the session is closed, the subscription is removed. Subscriptions don't last and end after a reboot
  • record_id(int) is used to tell the launcher what subscription it is
  • list_coulddescriptionmatter wayinstances that register all the attributes to which they are subscribed. May include wildcards
  • half_rangeimax_interval(in seconds): Tasmota waits at leasthalf_rangebefore sending the new value and send the message beforemax_interval(Usually a heartbeat indicates that the subscription is still active.) In general, feature changes are pushed immediately.
  • filtered_fabric: currently not in use

Here are the internal arguments:

  • Not before: The actual timestamp to wait before sending an update, sincehalf_range
  • Date of Expiry: The maximum timestamp we can wait before sending a heartbeat. Both are updated after we send a new value.
  • wait: indicates that we have sent everything and are waiting for the endstatus reportto continue sending more updates
  • is_keep_live(bool) if the last message was life support, if so, we only expect an Ack, not a Status Report
  • additions: List of specific attributes whose values ​​have changed since the last update. They do not contain a new value, in fact we will look at the value of each attribute when we send an update


This class (module) contains a global list of all active subscriptions. Method|Description:----|:--- init(im)|Create monad with global MI monad new_subscription(session, req)|Create session andSubscribeRequest message, parse the message and create itsubject.IM_Subscriptionexample.
he returns itbitno.IM_Subscription()example. It also assigns a new subscription ID.

What happens when an attribute is updated?~

Subscriptions are activated by changing the values ​​of the attributes. They can come from an explicit WRITE Matter command from an initiator or other device, as a consequence of a Matter command (such as turning on a light). The box also comes from an independent source, such as a Tasmota level action (using TasmotaForcecommand) or Tasmota detecting that the sensor value has changed after a periodic measurement.

Note: the default light plugins actually look at the Tasmot light state every second and report any difference between the last known change (also called shadow value) and the current state. We find this to be more consistent and reliable than trying to create rules for every event.

When the value of the attribute changes, you need to call the plugin's method

(bool) is optional and is currently ignored and reserved for future use.

Heendpoint_idthe argument is optional. If the endpoint is unknown, the message is broadcast to all endpoints that support reading these attributes:

More generally, you can use a global method to signal an attribute change from any code:

Note: internally this method creates amatter wayexample and calls, fabric_specific)
who in turn callsfeature_updated_ctx(ctx, specific_fabric)to each active subscription.

he is calling youattribute_update_ctx()first check that the attribute matches the filter criteria (which can include wildcards). If they match, the function is a candidate to be added to the list. So we call_add_attribute_unique_path()to check if the feature is not listed yet, and if not, add it to the list for future updates. It is possible that duringhalf_rangetime, the attribute can change its value multiple times. however, we post a single (last) price.


HeSubscription_StoreMonad checks every 250ms for updates ready to sendcada_250ms().

Performs an initial scan of all active subscriptions if updates can be sent:

  • membership not includedwait(i.e. without waiting for the previous exchange to finish)
  • the subscription has a non-empty list of updates
  • subscription reachedNot beforetimestamp (to avoid sending too frequent updates)

Yes that's how it is:

  • im.send_subscribe_update(sub)It is said that
  • update subscription list is removed viasub.clear_before_arm()

Once all the updates have been sent, the subscription is scanned again to see if a heartbeat should be sent:

  • membership not includedwait
  • the subscription has arrivedDate of Expirytimestamp Ako gives:
