Initialization of Sesto Senso

I've debugged the code and the problem is in the TimerHit() method. The temperature frequency counter is increased and then compared against the update frequency. When they match then the temperature is updated. In this case it only works once as the counter is never set back to zero. I've added the last line in the if statement and now it works as expected:
    if (m_TemperatureCounter++ == SESTO_TEMPERATURE_FREQ)
    {
        rc = updateTemperature();
        if (rc)
        {
            if (fabs(lastTemperature - TemperatureN[0].value) >= 0.1)
            {
                IDSetNumber(&TemperatureNP, nullptr);
                lastTemperature = TemperatureN[0].value;
            }
        }
        m_TemperatureCounter = 0;  // <- Was missing.
    }

Maybe someone with access to the repository can add this to the code .

Hi all,

I opened a case directly with Primalucelab and they say that hold current should be 5 mA or 10 mA at maximum. I have tested my SestoSenso with 15 mA and overheating disappeared.

Regarding temperature sensors, I've tried the one that Pegasus Software supplied with its Dual Motor Focuser Controller (DMFC) that I want to use with my Meade #1209 Zero Shift Microfocuser. It works fine with Sesto Senso but as described (read once only). It's curious, but starting temperature was 23.18 degrees.. the same obtained by NH... Coincidence?? :-)

I also tried with a similar sensor purchased from AliExpress for a couple of euros. They Don't work neither in Sesto Senso nor DMFC. I asked to Pegasus Software about 2.5mm jack pinout and they said that this kind of cheap sensors won't work with DMFC and only will work with the original one that costs 18€. Cheap if compared with the 45€ worth for Sesto Senso original sensor.

If someone is able to make work this kind of cheap sensors, please advise.

I will open a different thread with my DMFC issues. Jasem is working in that, but I have no news yet.

Thanks!

Hi again,

By the way, maybe could be a good idea add refocus feature based on temperature changes. I have at least two sensor in my gear: the one from Sesto Senso and the one from PPB from Pegasus Software...

Also some "temperature offset calibration" would be helpful to unify all temperature readings from the sensors...

Thanks

Thank you very much. :)

I have the original probe for the Sesto Senso. I agree that it is a bit overpriced but it is delivering very reasonable temperature values. The major downside for me is the long cable (~1m). I had to wrap it around my scope several times to get out of the way.

Hi all,

Apologies for hijacking the thread.

I have an issue with my Sesto which only manifests in Ekos. The problem I have is that no matter which direction I tell it to focus, it will always travel in. Never out.

I’m running on Win 7, latest stable SM build 1.4.0 and latest Kstars build.

Hopefully someone can help.

Thanks in advance.

If you download the nightly build you will get version 1.3 of the driver that solves this problem. Please read the last 3 pages of this thread for the details.

Thanks for that.

I'm a non-techie so can I ask for a link to the file and instructions?

To switch to the Beta Channel (latest nightly builds) follow these instructions: www.stellarmate.com/support.html?view=kb&kbartid=5.

Make sure that you have calibrated your Sesto Senso with the PrimaLuceLab software. When you have started Ekos look at the INDI Control Panel that the Sesto Senso driver is version 1.3. Then you can go to an absolute position, focus in or out. But do not set the maximum position in INDI. This should work with the next version of the driver (1.4). Rishi is working on that.

@Rishi:

Are you sure that temperature issue has been solved in version 1.3? Mine is still not working the right way... SentoSenso read the temperature when started but nothing changes if I heat it with my hands (to test).

Thanks!
