In HA you can set a scene that fire the commande you need to control your zigbee devices. You can even set a button that will fire the automation to change a parameter. You do the programmation once and use it easily after.
You can also have a look to ZHA Toolkit integration via HACS
I do not have a 1123zb-g2 but is the sinopebacklight attribute writable on these? If not did you fin a way to tun off the backlight on the g2? I think sinope changed the cluster/attribute or removed the option
Thanks, I will check the tool kit.
But for scene or script, I would need one per device, unless I find a way to extract the ieee on device call.
HI @MattL0 the backlight attribute is not on the sinopé cluster ,0xff01, but on the cluster 0x0201
Cluster Attributes Fonction Value
0x0201 0x0402 BacklightAutoDimParam OnDemand: 0, Always: 1
Sinopé cannot change that cluster but it is possible that it use it for something else. But it will go against the zigbee protocole.
On Neviweb the parameter for the G2 thermostat is âbacklightAdaptiveâ and it is usable so it should work with ZHA
@MattL0 beat me to the punch, I was going to ask the same thing. 
@claudegel is the Cluster & attribute for the G2 version the same as the first Gen ? or do we need to write new code just to make this one work ? (we are porting this code do Z2M and your work on this on the ZHA side is really helping us)
edit:
Tested with 0x0402 (1026) and its giving me a UNSUPPORTED_ATTRIBUTE for the G2. So the question is : Is it working in ZHA or is there a new code for dimming on the G2
Merci beaucoup

Hey everyone, Iâm thinking about something - Is there already a Discord channel about SinopĂ© and HA ?
It would be nice to talk directly sometimes. I see an active community here with more than 1200 messages since 2017.
If itâs not already existing what about creating it ?

I donât have a G2 connected to my HA so I can test wright now. The main difference with the G2 is in the out cluster list. they removed sinopĂ© cluster and added the identify cluster.
As it is the same attribute in Neviweb for the TH1123ZB and TH1123ZB-G2 it should be the same in ZHA.
Yes sorry . They just called it Sinopebacklight on zigbee2mqtt even if it is on the Hvacthermostat cluster.
It would be easier if I had a g2 with me . Iâll check.
If you have a spare G2 and live in the montreal region I can pick it and sniff the line on ZHA and GT130 to catch all the cluster.
Yes I live near Montreal. Thanks you!
Right now I am waiting for amazon. To ship one. But I am not sure It will be a g2 device. This is for the bathroom so, it can wait ( if it is a g2).
Iâll let you know.
Hello folks,
I bought 6 more Sinope thermostats on Black Friday for use in an old cottage and pumphouse heat control.
I installed one this weekend into the pumphouse, but got a strange message when trying to add the Thermostat to Homeassistant. The initial âinterviewâ seemed to hang, then I tried again and it added immediately, but the thermostat shows up with:
Device: Unk_Manufacturer Unk_Model
It seems to work (i can control the thermostat, and its responding fine to changes in set temp, etc.) but something is definitely wrong. Iâm a bit leery to try the âreconfigureâ option in HomeAssistant, only because this heater is very important right now to prevent water from freezing in the pump house 
I was worried it might be on the distant edge of my ZigBee network, but any thoughts on why it wasnât detected as a Sinope Thermostat?
Hi everyone,
The âlocal_temperatureâ entity of my 3 thermostats disappeared overnight.
I use zigbee2mqtt with the gauge card.
Do you know what could have happened?
Thanks!
Salut tout le monde,
LâentitĂ© âlocal_temperatureâ de mes 3 thermostats ont disparu du jour au lendemain.
Jâutilise zigbee2mqtt avec la carte gauge.
Savez-vous ce qui a pu arriver?
Merci!
Quel est le status de ton sensor.z2m_plancher_chanffant_rdc_local_temperature ?
As-tu toujours le control de ton thermostat ?
Maybe try to remove it and re-associate it. do you have any other issue with your zigbee ? sometimes frequencies can be in conflict with wifi depending on the channel used by your AP.
@claudegel Jâai eu SinopĂ© au tĂ©lĂ©phone ce matin et semble que les commandes avec Calypso RM3500ZB sont envoyĂ© Ă partir dâaujourdâhui 
Thx, Iâll give that a shot next weekend when Iâm back at the cottage. No other Zigbee problems so far (none that Iâve noticed, anyway!) Iâll report back next week.
Getting back into Home Assistant after a few years off HomeAutomation.
I have a GT125 and GT130. I installed neviweb and neviweb130 (dont care about talking directly to GT125).
Everything works well except for my old TH1500RF Double-Pole that wonât show up (2 other TH1300RF are showing).
I have this error log:
2022-12-05 16:34:00.754 ERROR (MainThread) [homeassistant.components.climate] neviweb: Error on device update!

Any clue?

Pas de status pour sensor.z2m_plancher_chanffant_rdc_local_temperature Ă©tant donnĂ© quâil a disparu.
Jâai toujours le contrĂŽle oui.
