Thanks a lot, I have one on order now

It's it ekos or the driver that does not support the temperature sensor?

What do you mean with 'not supported'? It works nicely, and reports proper values.
I think you cannot tell EKOS to refocus on temperature change, but that is not an issue of the EAF....

You are right. What I meant is exactly that: Ekos cannot be told to refocus on temperature change.

Just calculate the predicted temperature drop from the weather forecast and schedule timed refocusing sessions accordingly and you should be fine.

This can be added to Ekos... so it's just if temperature diff is above a certain threshold, then refocus? It records temperature on connection and if that exceeds the threshold , then autofocus?

Could a simple model, like a fixed focus-shift pr. temperature, also work, such that one does not need a full refocus but just some minor (semi-continuous) adjustments based on the temperature difference alone? Just a crazy idea...

I'd prefer a full refocus since minor (semi-continuous) adjustments need calibration by the user and the differences may vary per night.

I can do autofocus when temperature is above threshold... rest would take a lot of time

Oh, that would be great ! ... Can we chose the threshold (depending on ones F/D or focal length) ?

I agree, that would be a great addition to the capabilities of EKOS. Even more if at the same time both values (temperature and focus) would be added to the FITS header, that would make it much easier to derive a temperature dependence for those that want to do this....

I was wondering if anyone knows what's that status of this? Will a "refocus if the temperature difference is more than X degrees" feature come to an Ekos near us soon?

Hello all,
just seen this and there is an Autofocus if Delta Temp is bigger than a certain amount of degrees.

I have recently purchased a ZWO EAF and I have a Pegasus PPA (Pocket Powerbox Advance). I dont have a temperature sensor on the ZWO EAF but I do have on the PPA.
Which temperature is used for this condition?

The issue is that the ASI EAF has got a temperature channel which is clearly wrong (28C degrees at room temperature vs 20C read by PPA).
