Re: Simat 1 wire Hubs



Hi Jon

>now I'm thinking that it slows down the 1-wire network too much for my
>purposes.

Yeah i noticed that the branches get polled.....Im going to put moisture
sensors and any outdoor temp sensors on the Hub  and my Ibuttons on the
main
trunk along with the lcd that i have just ordered.. Dont for get though Jon
it take approx 700mSEC to read a dallas temp sensor this delay is not due
to
the HUB.....Luckily my room temp sensors connect to my Probe system so that
will reduce the scan time a bit.....I,ll have  a play with the lcd
connected
to the HUB to see what sort of delays i get.......
