Re: [Owfs-developers] ds18b20 always showing 85 as temperature output
Sorry. I got some wire shorted in my circuit that's why it wasn't working. now its working well sorry again.

Re: [Owfs-developers] owfs.org expired?
I have received a screenshot from Mike showing that he had the possibility to renew the expired domain. According to enom's FAQ it should be possible to perform a transfer of expired domain, but it must go through their support who can provide the transfer code. So, I have asked Mike if he could do that. Waiting for reply. Johan -- Sent from my Android device with K-9 Mail. Please excuse my brevity.

Re: [Owfs-developers] ds18b20 always showing 85 as temperature output
Hey, thanks for the reply. But meanwhile I got in new trouble. Owdir command sometime shows all the sensors but as I add a new one it randomly shows two or three sensors only. I am trying continuously for two days and same problem persists. I am using 7-8 ds18b20 with ds2482-800 and powering it through R pi 3b 3.3 volts. I am using external 4.7K pull up. Please tell a solution. Thanks in advance. On Thu 16 May, 2019, 17:36 Jan Kandziora, wrote: > Am 16.05.19 um 11:33 schrieb modi: > > Hi > > I am using owfs for first time.

[Owfs-developers] owfs.org expired?
I don't want to push it, but has someone (Mike) look into it about the expiring of the owfs.org domain? I wil take care of it if somen give me the domain transfer code. If you don't trust me, we can store it in a common place/safe.
