Zlinky-tic

speeed · Mars 24, 2023, 5:43

Je bascule du plugin zigbee officiel a Z2M
Pour l’instant tout c bien passé, j’ai réussi a reinclure tout mes devices avec l’interface du plugin jeezigbee
Enfin pas tous
Le modul Zlinky_tic me pose un souci à linclusion j’ai dû rajouter le type de commande numerique pour pouvoir sauvegarder le modul
Les commandes ne remontent pas.
Sur l’interface Zigbee2MQTT je vois bien que l’intégration est complète avec les valeurs qui remonte bien.

S’agit-il d’un bug ou alors je fait mal les choses
Ps: SINSTS correspond a la puissance apparente

merci

Bonjour
Il me faudrait le json brute de l’équipement pour pouvoir faire l’analyse.

merci je vais faire ca ,il faut que je reinclu le zlinky_tic sur le plugin jeezigbee
Parce que j’utilise le plugin zigbee en cohabitation avec le plugin
jeezigbee pour le module Zlinky pas la meilleure solution mais cela fonctionne

Merci je regarde courant de la semaine. Tu pourrais aussi me mettre une capture de la page de commande de l’équipement que jeedom crée ?

speeed · Mars 25, 2023, 9:15

Merci Loïc pour le travail désolé pour la capture d’écran je suis passé par un site web je ne sais pas comment faire une capture d’écran en défilant la page jusqu’en bas
a l’inclusion je suis obliger de completer sur une douzaine de commande le type de commande (numerique) pour pouvoir sauvegarder le modul

speeed · Mars 25, 2023, 11:20

Loic · Mars 26, 2023, 10:04

Bonjour,
J’ai deja trouvé un soucis mais ca corrigera pas tout, pourrais tu m’envoyer ton log z2m ? Il devrait avoir dedans le nom logique de la commande que jeedom recherche et je pense le soucis vient de la.

speeed · Mars 26, 2023, 10:20

z2m.txt (371,4 Ko)

merci j’espere que c celui-la

speeed · Mars 26, 2023, 10:23

apres avoir inclus le modul

z2m-news.txt (117,5 Ko)

Loic · Mars 26, 2023, 10:46

Ok je pense avoir trouvé, la maj devrait etre dispo dans quelques minutes (le temps que le robot valide mon code). Il faudra supprimer l’équipement de jeedom et le recinlure.

speeed · Mars 26, 2023, 10:48

Merci Loïc
Un SAV même le dimanche incroyable
Je ferai un retour sur le forum bon weekend

speeed · Mars 26, 2023, 10:56

1000 fois merci
Mise à jour dispo aussitôt appliqué
Je n’ai même pas eu besoin de réinclure le module
Vive jeedom

Loic · Mars 26, 2023, 11:21

Cool bonne nouvelle, et oui elle le dimanche mais tu es un des rares a le remarquer…

speeed · Mars 26, 2023, 12:38

Loic, je ne veux pas abuser , dans le .json du plugin zigbee
Il y a un refresh des infos que je ne retrouve pas dans celui de jeezigbee
Encore une fois, rien ne presse.

LiXee.ZLinky_TIC.txt (5,6 Ko)

Loic · Mars 26, 2023, 1:33

J’ai pas encore mis la notion de refresh des info en jeezigbee car pour le moment yen a jamais eu besoin. Es tu sur que c’est utile ? Avec l’ancien plugin oui mais le nouveau je suis pas sur.

speeed · Mars 26, 2023, 1:37

Enfin pour ce type d’équipement ça m’est utile parce sur le Zlinky_TIC
Le rafraîchissement auto de la conso ne fonctionne pas toujours bien
Pour connaître la conso a l’instant présent
Enfin je ne suis pas tout le monde
Si ça y est c’est mieux , sinon tant pis je me contenterai
Cordialement

Loic · Mars 26, 2023, 1:40

Tu as vérifié que le problème existe toujours avec ce plugin ? Il intègre déjà en interne des systèmes de mise a jour automatique des valeurs ce qui n’était pas toujours le cas de l’ancien plugin.

speeed · Mars 26, 2023, 2:11

Merci pour ton message je ne voudrais pas polluer le forum
J’ai un souci plus important
Au départ quand je te dis que tout fonctionnait je n’avais pas réinclue le module ne voyant pas la commande refresh j’ai décidé de réinclure le modul
Aussi bien sur l’interface zigbeemqtt
Que le plugin jeezigbee
J’ai vérifié le démon
La page santé tout est ok
La commande SINSTS
N’apparaît plus les informations semblent bloquées
pourtant dans le json elle est bien la
info du module.txt (16,4 Ko)
