Some news from the kitchen. I have success with Temper and TemperHUM sensors
Both are fully supported by APT now. v1.10 shows temperature, humidity and dew point (last two needs TemperHum sensor)
The registered version has more goodies - refocusing notifications and notification for closing and passed dew point. In the settings dialog you can set the temperature change that forces refocusing, and how many degrees before dew point to notify.
You can see an animation that shows how refocusing alert works. First you set Focus Mark (with simple click on the F button). When the temperature pass half of the limit then T: becomes flashing to show that soon you have to refocus. When the limit is passed then T: becomes bright red
If the work continue with this rate we will have new version before the end of September
