Add "OFF" mode like in the Hilo/Sinope apps

[sebjacob]

Is your feature request related to a problem? Please describe.

Many Sinope thermostats (including older models such as the TH1120 series) support an "OFF" mode in the official Sinope and Hilo apps. However, the Home Assistant “Sinope Local” integration exposes only limited hvac_modes (e.g., heat) and does not allow switching the thermostat to OFF. This means that a key device function is unavailable in Home Assistant even though it works locally through the hub.

The first automation I want to do with this is create a mapping of door sensors to baseboard heaters that will turn them off when a window/door is open

Describe the solution you'd like
Add support for the OFF hvac_mode for Sinope thermostats via the local API. Ideally:

• Expose hvac_modes: [heat, off] where supported
• Allow sending the command to set the thermostat to OFF
• Preserve and restore the previous temperature when switching back to HEAT (same behavior as the Sinope/Hilo app)

Describe alternatives you've considered

• Using the temperature setpoint workaround (setting very low temperatures), but this is not the same as OFF and still engages heating logic.

Additional context

• Sinope and Hilo apps can toggle OFF natively on the same devices.
• Devices are bound to the Sinope hub, so this integration is the only local path.
• Adding OFF would bring feature parity with the official apps and improve automation flexibility.

I don't know if you meant to post this in the Sinopé repository, if so, head here:

I do not personally own any Sinopé heating devices thus am unable to develop or test for this.

Furthermore, I do not think setting 5C on a thermostat is any harder than toggling it "off", automation wise, and your rooms will likely never reach 5C, thus never engaging any heating whatsoever.

The Hilo integration is still wholly dependent on Hilo's cloud infrastructure to work, none of it is actually local except some scheduling once a challenge is received. If you want truly local control I suggest you invest in a proper zigbee or other dongle and use Zigbee2MQTT or similar to control your devices. Using HA, to control Hilo, to control Neviweb devices is quite convoluted as it is.

While I don't mind leaving this issue open for visibility, this is not likely to be worked on.

Have a good weekend.

It's not as convoluted as it may seem, I'm just asking if we can have the heating modes in the hilo app exposed in HA.

To get sinope devices on Hilo, you need to add them via Neviweb.

In practice, for home assistant, this hilo integration is actually more noticeably responsive than https://github.com/claudegel/sinope-130

so I'm just using the Hilo integration in homeasssistant now (because I get the power meters as well!)

The main reason I would rather get "off" than setting 5c is that I don;t have to keep track of what the temperature was set to before I set them to 5c.

setting to off and on again makes this simpler.

I have a full zigbee2mqtt back-end here, but the rebate on the thermostats require to keep the thermostats on hilo for a couple years.

Not quite true, quite a few users got the subsidy and promptly shelved their gt130 to go full z2m. You actually agreed to participate in the challenges, not to keep the thermostats linked ;)

Feel free to come see us on discord, there's quite a few users on there:

Currently I’m running both sinope and Hilo add-on for my automation. The only thing I’m using the sinope implementation is to turn off thermostats. My use case is for the garage, the temperature goes below 5c during a peak. At 45c/kwh, I really don’t want to it turn on. I’ve got the wifi’s unit installed by HQ themselves so going z2m is not an option. It could be a great addition imo

Looking for that too. I need to turn some Thermostats to Off but need to use the Sinopé integration only for that.

If anyone wants to donate a wifi thermostat, a zigbee thermostat and a gt130, sure, I'll try and make it work. Without that, this will not be worked on, at least not by me, seeing as I have nothing to test or debug with.
