Hello,  
Does anyone of you know if it’s possible to get higher temperatures with thermostatUI? It looks like its max is 35 degC, even if I set bigger max value on capability. I need that for thermostats for hot water or sauna, where - of course - 35 degC is too low. Using sliderUI instead thermostatUI isn’t that comfortable and precise ☹

I think it is a ‘build-in’ limit to the `target_temperature` capability, but it’s not mentioned here [Capabilities - Homey Apps SDK](https://apps.developer.homey.app/the-basics/devices/capabilities)  
Sending a request to Athom is all you can do atm. I think.

target\_temperature capability options for max and min values do actually work.

One example:

> <https://github.com/oh2th/io.ohmigo/blob/main/.homeycompose/capabilities/target_temperature.json>

Also you can call updateCapabilityOptions to even change them from code:

> <https://github.com/oh2th/io.ohmigo/blob/main/drivers/main-device.js#L209>

Thanks for all the help, I found a typo, I’ve made in the code, that’s why it didn’t work.
