FADU F-STOP ENLARGER TIMER



The project files for the FADU F-stop Enlarger Timer have now been moved to GitHub as that is a more appropriate place to maintain the project - but read on for an overview and release...

Hi Bob,
Yes itís on the same network.
If I ping to the iP-address it responses with ony msecs figures.
I will dive into it later this week and let you know if I find anything odd.
But, thanks a lot for your help :-)

No problem at all. If you are getting good times on your network, it might be worth trying the timer in [BASIC R3] mode - my network throws up random bad delays so I can't use it. It does not have the 500ms restriction.

Also, you could try using RESTer with Chrome as per the manual - see if that works for you instead of Postman - the first example is the /info command. If that works OK then you can think about re-programming the Sonoff Basic R3 with the new firmware using OTA as that gets rid of all the issues with network delays and Sonoff's poor API implementation...

Oh, BTW, another thing Sonoff neglected to mention in their API documentation is that to use the Inching API you need to first setup the pulse length using the zeroconf/pulse command and then use the /zeroconf/switch command to actually turn the Sonoff on.


Have fun!

Default Using direct network of Sonoff Basic R3

Hi,

thanks for this great app! I just ordered a Sonoff Basic R3 as both of my enlarger timers stopped working. As I don't have any wifi signal in my darkroom (that I have to build up every time) I was wondering if I just could stay in the setup network of the Sonoff without changing any settings. Did someone try this yet?

In case this does not work I would have to build up a wifi network using a separate router, right?

Thanks!

Christoph

Hi Christoph.

I did not see any way to use the Sonoff in its standard configuration/firmware without connecting it to a local WiFi router so I think that you would have to use a spare router. If you find a different way, do let me know - that would be very useful.

If you have a spare router you can dedicate to this, it should work well using the "Basic R3" controller mode as delays though the router will be minimal with no other traffic on that network.


As an alternative to using a separate router, you could reprogram the R3 with the new firmware which allows your Android device to talk directly with the R3 without any other WiFi hardware. This is a bit awkward to do but provides the best accuracy by eliminating the delays caused by the router relaying signals.

I can make things a little easier by supplying a previously compiled version of the firmware file so you do not have to go through the whole Arduino process to create a new one. I only realised that supplying the firmware file would makes things quite a bit easier for most people a few weeks ago - I have been messing about with embedded software for a long time and forgot that not everyone has!

Let me know how you get on and if you have any more queries.

Incidentally, it may be worth ordering a spare Sonoff - especially if you want to try reprogramming one - it is possible to kill it if the programming goes wrong...

Cheers.

Hi Bob,

thanks a lot! I think I will go for the spare router. I have old unused ones lying around so it's worth a try. And I am happy if I don't have to do too much on the hardware side like soldering especially when it has to do with higher voltage setups.

I will let you now if I find out anything interesting.

Thank you once more!

The advantage of the Basic R3 (and the Sonoff Mini) is that it can be reprogrammed via WiFi rather than needing to solder wires to it, but yes, if you have a spare router to dedicate to the job, that will work well too. Have fun!

Oh, really? Then maybe I'll think about it. It seems to be a good idea to get rid of the extra router. But tonight I hopefully will have the chance to try it with the router setup first.
