Controlling relays with URL commands

[tscholand]

Hi, I just started using BSB-LAN and love how it helps me to make my heating system smart. It's a great project!
I ran into one issue: I'm trying to switch one of the relays of the ESP32-Olimex EVB by the use of URL commands.
When I request /G32=1, it successfully switches the relay on. But as soon as I query /G32 (without the =) to see the state of the relay, it switches it off. Is there a way to see the current state without switching it off?
And is it possible to control the relays via the JSON API?
Kind regards,
Tim

Hi Tim,

thanks for the feedback, that of course shouldn't be the case. Can you try two things please:

1. Can you call /G32 once when the relay is on and once when the relay is off? Even though it may turn off eventually, is the status shown correctly? Or is it always 0?
2. Can you install release version 3 and test the functionality? The rest of the heating functions may not work, but that doesn't matter, the /G URL function should still work. The reason for this test is that I want to ascertain whether this is a problem that resulted from some code changes or has always been like that (which I could not really imagine).
   Thanks!

Wow, super fast reply!

1. The status is always shown as 0 - no matter, if the relay is on or off before querying it.
2. I can try to install version 3 and will report back after testing.

Ok, thanks. In older versions, there were two syntaxes possible, one as /G32 and the other one was /G32,I. Please try both of them and compare the results. Thank you!

Hi Frederik,

I just tried to install version 3.0 and 3.3, but failed. It does not compile for me. I only renamed the files BSB_LAN_config.h.default and BSB_LAN_custom_defs.h.default. No other changes.

I keep getting these errors on compile:

Compilation error: 'ETH_PHY_ADDR' was not declared in this scope; did you mean 'ETH_PHY_MAX'?

Anything I can do to fix this?

[fredlcore]

Yes, you have to use version 2.x from the ESP32 framework, not 3.x. Then it should compile...

[tscholand]

Thanks!
I still struggled a bit to get it to compile. I had the error ModuleNotFoundError: No module named 'serial'. After installing the python3-serial package on my machine it worked.
I can confirm, that with BSB-LAN Version 3.3.5-20240311105434 the switching of the relay works as intended. Switching on and off works and also querying of the current state works fine!

[tscholand]

With the /G32,I however, it still switches the relay off, when querying the current state...

[fredlcore]

Ok, thanks! But I'm confused now because you say that querying works with version 3.x, but then you say it doesn't with /G32 - which way does it work then?

[tscholand]

Sorry, what I meant was with version 3.x it works, when querying /G32, but it doesn't when querying /G32,I. With the I it switches the relay off. Without the I it works fine.

[fredlcore]

Ok, thanks, I'll look into the code segments to see what has changed since then...

[fredlcore]

Ok, found the problem. I removed old code at one point, thinking it would not be necessary. But, apparently, it is ;).
Setting a GPIO to "input" is only necessary if there is a sensor connected to it. Otherwise, it's possible to read the value of an "output" pin without setting the pin to "input" first. /G<x>,I sets a pin to "input" to define the pins state, but this has the abovementioned effect on "output" pins. On the other hand, setting a value to a GPIO automatically drives the pin as "output". Bug is fixed in the most recent version.

[tscholand]

Great. Thank you for this quick fix!
One question remains: Can you control the GPIOs via the JSON API? Would be easier to integrate into a smart home system.

[fredlcore]

No, that is not possible, and not currently in the pipeline.
