Average two sensors

[dudo33]

I am just starting my conversion from ST. I have a few webcore pistons setup and I am struggling to learn Rule Machine now. One of my pistons controls a bathroom fan by comparing the humidity level in the bathroom to the average humidity level of two other sensors in the house.
Can you compare A to (B+C)/2 with Rule Machine?

You can with this app.

[UPDATED] - Average All (Temperature, Humidity, Illuminance, Ambient Pressure & Motion)

I found a need for an app & driver to 'average out' temperature, illumination & humidity. So here is a little app and a couple of device drivers to do just that. This is a parent/child app so you need to install both parts before 'loading' the parent . This also comes with three virtual device drivers so you can create virtual temperature, illumination & humidity devices for use in other apps. After installing the parent you can create as many of the child apps as you wish (You need to creat…

Also have a look at ‘super smart fan’
This compares humidity levels and controls a fan based upon the comparison

Bathroom Humidity

OK guys.. Here is the first draft of the 'Super Smart Fan' If configured correctly it should: Turn on the fan when it's too humid (turning off when humidity returns to a normal level - based on a baseline sensor) Turn on with motion. - Turn off automatically after a pre set time period when motion stops (if humidity is normal) Turn off automatically after a pre set time period when manually switched on (if humidity is normal) You can find the app here: Have a thrash about…

If you want an all in one solution, Bangali's Room Manager is a great option. It has a humidity management setup as well, which includes comparison checks, value checks, etc.

Rooms Manager: Smarter Rooms: Personalized home automation with Occupancy

[image] Rooms Manager with Rooms Occupancy While ST has a concept of rooms it is essentially a grouping mechanism which does not enable personalized automation. In contrast rooms occupancy considers the room as a meta device and automates common tasks associated with a “room” physical or virtual. What makes it really useful is not just the room's occupancy state but the ability to manage automation for rooms in a set of rules for the room based on the occupancy state of the room and data from v…

Thanks for the tips guys, I will check out all three of these options.
