Re: How turn on heating of my DHW storage tank
Thanks for your answer. Sorry that I was confusing by using another name. I’m new on the forum. Indeed, my Vaillant answered with “unk-DataId” on command AA=26 (see log below). So the OTGW does not receive the DHW temp from my Vaillant. But I’ve added an additional sensor on top of my separate DHW s...

Re: How turn on heating of my DHW storage tank
Some additional information. The matrix shows the values for Vaillant Ecotec Plus CW. I have a Vaillant Ecotec Plus Solo . Solo means external DHW tank. The types with a suffix CW are types without a DHW tank. The boiler starts only with heating the water when you open a "warm water tap" i...

Re: How turn on heating of my DHW storage tank
Sorry, I missed your answer. In the meantime, I figured it out. Indeed, after setting the value “otgw_dhw_ovrd_gateway_cv “ (= override dhw) in HA to 1 (= enabled), my Vaillant started immediately with the heating of my separated storage tank. Even without changing the “DHW setpoint” which remained ...

Re: OTGW not working anymore after upgrade to V5.8
Today, I received the P16F1847 PIC that I ordered at Nodoshop. I replaced my old (deprogrammed) P16F88 by this newer PIC. And I could easily install the latest firmware V65 to this new PIC (via OTmonitor - upgrade). It took probably 20-30 seconds. And it seems I have all the values back that I had w...

Re: OTGW not working anymore after upgrade to V5.8
Sorry, I'm probably too new/stupid to understand your answer. I saw this firmware on the Nodo website "OpenTherm Gateway ESP Firmware". I didn't understood that this is for another product. But yes, I have an OTGW with an ethernet port. And probably with a 16F88 PIC Extra info to my latest...

Re: OTGW not working anymore after upgrade to V5.8
Thanks you for your answer. The reset button in the middle seems to work. By pushing, the resistance between two pins drops from +/- 100K to 0 ohm. (and for two pins) 10 seconds after the message "please manually reset", I pushed only once on the reset button for about 2 seconds. But the u...

OTGW not working anymore after upgrade to V5.8
I have an OTGW with an ethernet port. With the OTmonitor of march 2023, I tried to do an upgrade to the version 5.8. But the upgrade stopped after several minutes and several errors. Now the OTGW does not function correctly anymore. I can do a ping, and the otmonitor seems to connect. But when tryin...
