Sensor Group

Configuration
1

Hello can anyone help me:

I want to create a sensor group that:

State = ON when 2 sensors on the group are on
State = OFF when all sensors on the group are off

The group Contains 11 Sensor
Now works:

State = ON when 1 sensors on the group are on
State = OFF when all sensors on the group are off

Thanks

There is an option for that

i dont get how to do it

all: true

I assume you must create the sensor in yaml

i think he’s not asking for all. but for “any 2 of the 11”

i think if you create a binary sensor template with this template, it will do what you want

{{ expand (state_attr('sensor.group_name', 'entity_id')) | selectattr('state', 'eq', 'on') | list | count >= 2}}

so you have your existing sensor group.
then you have this new one that uses the first and counts how many are on.

if you don’t want to have 2 sensors, you could manually enumerate all of them instead of doing the expand that i did above.

I know this reply is a year late for the OP; but in case anyone else reads it - an option to investigate is set up a Bayesian group.

You could set a threshold and then set the probability if true for each sensor as 51% of the threshold value so that it evaluates as true if any 2 of the 11 sensors are on
