I have not used yet but I intend to use this hub

Then I will hang off 3 cables - temp sensors, PIR and a humidity
branch. I need to poll the PIR and humidity much more than the temp

Not to my knowledge is there anything commercial that deals with
1-wire like this, thats why me and others I'm sure roll our own.
