Re: OTGW firmware 5.0
Just flashed the 5.1 firmware without any problems. The LEDs now work again and return water temperature is being reported. Also updated the otmonitor on my RPi to version 5.1. When I use that software it shows that 'Flame status' is ON, 'CH mode' is ON and 'CH enable' is ON and 'DHW mode / enable' ...

Re: using ds18b20 for return water temp
Yes, that's the setting.
After flashing the 4.2.5 version the LED's did not work. after a powercycle they started working. Maybe some inits for the outputs not working?

Re: using ds18b20 for return water temp
Not absolutely sure but also checked gateway mode and did not work either. Another strange thing was that when I used the 'PR=' commands it did not always respond. In the log you could see the command but no reply. Please mention this in the release notes that you should use 'gateway' mode when you ...

Re: using ds18b20 for return water temp
For test I've flashed the patched 4.2.5 version and after a few attempts that worked. After a power cycle all LED's are ok and the return water temperature also works.

Re: using ds18b20 for return water temp
Hello Schelte, Thanks, this is great! On my Pi I've installed the new otmonitor software which now reports version 5.0, so that's ok. Using the new otmonitor I've upgraded the firmware on the OTGW which worked perfectly, it only tooks a minute or so and worked at the first attempt. The PR=A command ...

Re: using ds18b20 for return water temp
Ok, thanks. Looking forward to version 4.3. When released, is it possible to post a message in this forum?

Re: using ds18b20 for return water temp
You have a new version released: 4.2.8.1. Is it possible to have the source of that version available for download so I can patch it to be used with the temperature sensor for the return water temperature?
Thanks!
Thanks!

Re: using ds18b20 for return water temp
With the patched version of the OTGW firmware it looks like the modulation level is not reported correctly.
Is it possible to upload the v4.2.7 source onto your website so I can use the most recent version?
Thanks!

Re: using ds18b20 for return water temp
Downloaded MPLab, edited the code and compiled it. Then flashing the new firmware took some time. The otmonitor reported that it could not switch into programming mode and you had to reset the OTGW. After many attempts it started programming for about 15 minutes and then it worked!! I used the 2 pin...

Re: using ds18b20 for return water temp
Ok, I understand there is more to it. I'm interested in this value to check if the generated heat by the boiler is dissipated by the system in a proper way. Now with a lot working at home I've installed a 'zone system' to be able to heat separate rooms. That all works fine but if the boiler only has...

Re: using ds18b20 for return water temp
It would be a great option for boilers that do not report the return water temperature.

Re: using ds18b20 for return water temp
Any News about including this option to use the outside temperature sensor for measuring the return water temperature into the standard firmware of the OTGW? Doing the suggested firmware modification as shown looks somewhat complex and tricky....
Thanks
Thanks

Yes that's what's happening.
