This independent observation seems to confirm a driver problem. I will post a bug report on GitHub.

github.com/indilib/indi/issues/1951

Looks like Jasem committed a fix for the driver so if your able to take bleeding-edge changes you should be able to try it out.

Updated driver doesn't fix it. Now getting a serial write error

2023-10-10T14:22:21: [ERROR] Serial write error: Timeout error

Let us know how it goes.

I can confirm the same problem.
The initial temperature will be displayed, but after that there will be no more updates and the dT will remain 0.


EKOS:




INDI:

This happens also with 3.6.6 and MyFocuser 2 or other source like PlayerOne o WeatherRadio. I think that is not a problem related to the driver but of the Focus module

The serial write error is not reproducible and I have seen the temperature update with the newly modified driver from GitHub. I am now on business travel so can’t do comprehensive testing to confirm it is well and truly fixed but will do so on my return. My other system has a Nitecrawler focuser and the temperature does update there so it isn’t a common issue across different devices although it could be in other drivers I suppose.

There are few things here:

1. Thomas had/has a problem with his Esatto. Jasem pushed a fix which initially appeared to have a problem but on retrying appeared to work. The initially reported problem looks to be fixed but there may/may not be a serial write issue - Thomas will do more testing when he has time.

2. Fitchie, are you on the latest version of the Esatto driver (it was fixed a couple of days ago). If not, can you try that please. If its still a problem please post a log with verbose Indi, focus driver and focus ticked.

3. Alessandro, since you have a MyFocuser2 if you are not getting temperature updates then this is likely a separate issue so can you please post a log with verbose Indi, focus driver and focus set.

Thanks all.

Just re-compiled a fresh indilib, and ran a test against an Esatto3 focuser, using CCDCiel as the Indi client : on my side, the external temperature sensor issue is fixed, as the temperature is updated every 5 or 6 seconds.
Thanks to the developper(s).

No, I didn't but do now.
Temperature is updated each 5 seconds.

Thanks!

The serial write issue has never reoccurred but I am having issues with temperature update. I am running the latest Esatto firmware (3.5.13) and kstars 3.6.7 with the driver updated from git. The temperature seems to update sporadically and goes long periods without updating despite varying outdoor temperature.

Hi Thomas,

Good news on the serial write error. I think we can say that that was a one-off and no longer an issue.

On the sporadic temperature updates... the driver updates temperature every 10th polling period. So, if you poll the focuser (setting in Indi tab) say every 2s, I would expect a temperature update every 20s.

I suppose a way to check.this would be to put the temperature in a rapidly changing temperature environment and see what the update frequency is in Ekos.
