Tak už se mi to podařilo vyřešit

při dávkovém přidání retainu se nějak smazali přejmenování, ale tvářili se nesmazané. Nakonec jsem všechny co házeli chybu (kde jsem měnil retain) smazal a v autogenu přiřadil znovu jméno. Jenom, netuším, kde zlstali zahnízděné ty jména, protože z historie jsem je smazal taky

Ahoj,
v mém (prvním) projektu nastala divná chyba. Normálně vše fungovalo, ale pak jsem zjistil, že defaultně generované CNT proměnné DI nejsou retain, při pokusu o změnu na retain (označil jsem všechny a pak jsme dal mzenit vlastnosti a zaklikl retain) přestal program kompilovat s následující hláškou viz obrázek.

Mohu to nějak napravit?

What do you mean with ST program?
I had an Idea to build wifi temperature sensor using "mode mcu" (http://www.jerome-bernard.com/blog/2015/10/04/wifi-temperature-sensor-with-nodemcu-esp8266/) and write values into some file on rsb (or somewhre else in local network). Then read this file with mervis. I need update every 5mins.

Hi,
thanks for answers, I had installed previous beta mervis, I succesfully log into console (even remotely), but I am not able to apply answers from rasberry sites (or debian). f.e. sudo doenst exist, so I cant install any utils.
Karel (and me) probably wanted clasical graphical interface from rasberry. I dont know if it is possible to start it. (I am going to buy another SD card for testing)

I have one other question. In mervis IDE there is help/download new version and it want login (on energocentrum). Should it work or not?

It is possible to make new tutorial which will show how to read some values from online updated file? I will need some wireless temperature sensor, which can be readed this way. Or is there any other option how to use wireless sensors?

thanks for patience with us noobs (at least me)

Hi I have same issue. I installed latest beta mervis to SD and I am triing to login to rasp to enable wifi. (I read somewhere in forum, that I can manualy write something into some config file, but didnt tried) . I tried to use ssh too, but it wanted same user name.... root/raspeberry doensnt work for me

For mervis, I started with tutorials and basics are easy. I am stuck only on how to update (resync) PLC properties if I want to use some provided program. PLC operation/PLC setup/ download configuration doesnt work for me (I dont know if it should). I have issue to upload chenged program after few days (probably IP changed because I have to unplug everything every day)

I would like to ask exactly which tipe of battery is right one, I cant find it in manual and google doensnt help either)

thanks for quick answer and guidance
After fast look into documentation, I have found that for all DI for external power source I have to switch all JP2 to JP5 to label side

Hello,
I would like to implement home floor heating into mervis.
I would like to ask if there is any recommended functions inside mervis (all in one pack), or I should use some setup of more functions (delay,PID,some temperature dependent function).

Hello,
I have bought UNIPI home solution with pack (with mervis) and I am testing now. I found a small issue.

I have external pover source (12v) to buttons which control external bistable relay(schrack RT424F12) switching hi power relay with 12V any 12V coil relay. I would like to get signal to digital input too. Because the power source is izolated I have no potential on DI so I didnt get any input. I am not sure where I should connect GND from external power source to get signal to DI. Internal 12v source works fine, but I would like to avoid single point of failure issue.

Zkrátka rád bych jak jsem psal výše ovládal pomocí UNIPI pouze pomocné relé, které bude zároveň možno ovládat pomocí tlačítek (UNIPI bude pouze nadstavba). Externí zdroj, co má odtížit UNIPI je galvanicky izolovaný a DI nevidí žádný signál. Kde mohu spojit nulu, aniž bych to spálil?

Hi Tomas,
I would like to ask if the unica sensor behave as one 1temp device or as more than one

Hello,
thanks for answers.
ad 1) I am not sure if this solution is robust enough to me. but it is good to know. Still my wife can kill me if no lights is working:) I think about to add some auxiliary relay to get information about state of primary relay, but it is 2x relay (outside UniPi) and 1xRo+2xDi so quite expensive.

I have found another questions during the night.
3) Is there any recommended light sensor to get S0 signal from electricity meter? I think knowledge about energy consumption is good to have. I have found whole solution , but is it overkill with UniPi board.
