@akula3 you can have multiple additional sensors, to measure temperature. What they mean is up to you, just go here: https://github.com/rvdbreemen/OTGW-firmware/wiki/Using-DS18B20-sensor-with-ESP-firmware This is the option where you use the ESP to actually have multiple sensors. It's not done by the OpenTherm Gateway PIC, that's another way of doing it. |

This option to add a DS18B20 to your setup directly to the ESP does not influence other functions. It just gives you the option to add temperature sensors, multiple in fact as they are single wire. On the latest version of hardware you have additional pads on your OTGW PCB to simply wire your sensors. Make sure, this is NOT the PIC feature, but it's in my firmware. It also just added the temperature as an MQTT message. So some setup required, but it seems to do for people that have used it. I have had one user connecting 9 different sensors. |
