I have a similar for my Neuron L303. I didn't check via Mervis, but I just noticed that the indicator LEDs on the unipi itself was not reacting in any way anymore for some specific DI (others still working).

Do you think this is due to the same firmware issue or a more fundamental hardware issue? And why would I only have this issue now? I have only been running my unipi for some debugging purposes up until now (it's just when experimenting with my actual full set of push buttons that I started to notice this).

Hi @arolli,
can you share more about what you are trying to achieve?

Thanks,
Martin

Hello @arolli,
this is described in the Mervis help files (F1). Look for "B31" and you will see that the input parameter is type "CONTROLLERTYPE" with a hint how to use it.

Best regards,

@tomas_hora, thank you.

I have been reading more about your products and I found out that EVOK provides websockets. I was thinking that I would write a script which would process MQTT messages from a dongle and deliver them to Mervis using websocket and the other way around. Would that work? It would replace the Node-red which you suggested.

Thank you for your help, Martin.

Hi @arolli,
yes, you can start all 4 relays at the same time.

Hi Martin,
in my 1wire bus I've 3 HUB and several sensons. Everything is working fine.
Only problem appear when on the last port on my last hub I connected a rj45 splitter
( https://www.unipi.technology/1wire-hub-2-port-p50 ).
After a while I connect the thermometer to this hub it disconnect. (it appears red in mervis)
All RJ45 port are cabled whit pinout TIA-568B and thermometer are cabled as follow:

+VCC: blu + blu/white
GND: brown + green/white
1W : green + brown/white.

Do I need to use the same schema of connection on the thermometer atteched to 2 port splitter?
let me know if you have suggestion how to troubleshoot the problem.
Thanks
Antonio

Hi Martin
I follow the suggestion to set autogen only on needed variables (just DI and DO_w).
I solved the issue.
thanks
Antonio

Hello @arolli,

1 - You should find question in the knowledge base
2 - You can have multiple instances of Mervis IDE installed on the same time on your PC. Mervis will ask you which version you wish to use on startup.

Hello @arolli,
the new Mervis release is being expected in upcoming weeks, hopefully by the end of this month.
