Problem solved! I mixed the two diodes (15v and 4v3). Soldered them in the correct order and everything works.
I get full info from Thermostat and Boiler now and I'm able to set different parameters.

Thanks Schelte for replying!

I understand the info is minimal, but thats what the monitor shows, only this error.
I believe there is a mistake with soldering.
I'll go through the components and troubleshooting guide tonight. Any findings i'll share asap!

Thanks for replying!

Hi,

I've got the OTGW up and running, but it seems to have a problem.
On my thermostat (celcia 20) I read "fout 203"

Could someone point my in the right direction?

Thanks,
Jasper

Hi Geert-Jan,

First of all, thanks for taking the time to reply!

Does it mean you have the otgw soldered as if the otgw is the usb version?
Than use rx tx pin on the rs232 for connecting to two digital pins on the jeenode/arduino?

Hi all, I'm new to the OTGW, but learning ;-) I've already asked this question, but in the wrong forum (my apologies for that :oops: ). I would like to hook up my OTGW to an Arduino, but struggling a bit how to exactly do that. Schelte already suggested to remove the IC2 "and hook up the two se...

Nobody who can help with the OTG <-> Arduino connection?

Anyone willing to help me out, or point me in the right direction?

My arduino is connected via WiFi to my network and Openhab The communication between arduino and openha...
