  @kalophain if 1wire sensor is loaded to the channel, it's ID is stored in the non-volatile memory and so it should be restored upon boot of the gateway. Since the memory is tested on every piece, the probability that it no ok is really low. The DIP switch is used for firmware change and has no affect to the store/load of the sensors. Please make sure that: the baudreate in Neuron and GW is the same check that the addresses stored in the GW and loaded from the neuron are the same upload the latest FW 1.24 to the GW loadand save the sensor to the channel multiple times

  Dobrý den @beny44, náš 1-Wire hub je pasivní zařízení, které spolu s našimi 4 vodičovými čidly napomáhá vytvoření správné 1-Wire sběrnice - tedy serializované a bez odboček. Pokud se rozhodnete zapojovat čidla vlastní, pak použijte schéma pro aktivní napájení, ne parazitní. Odpor ve výše uvedeném schematu vynechejte.

  Hello @qcomp we don't have direct experience with these devices, but it is quite simple to connect them to our PLCs through Digital Inputs. I recommend looking into our Counters functionality which can give you more precise results during high water consumption periods. The process is the same as measuring electricity consumption through S0 output of energy meters - 1 pulse equals to some defined amout of energy / water .

  In theory it should work the same as any other extension we have, though we cannot guarantee it, since some devices deviate from the standard protocol in one way or another. Either way you will need to create a custom ModBus map, whether you are using Evok, Mervis or something else.

  @dickesc Not sure, they are also using I2C and some microcontroller. You would have to check their documentation and ours documentation if there is no conflict with GPIOs, I2C, SPI,...

  Hello @viestivelho, 1Wire has only one data pin from its design, and that is pin 7 on the master = the UniPi. Besides that we use another wire, pin 6, to serialize the bus as much as possible to maximize the reliability. That pin is wired only in the temperature sensors and HUBs which we provide.

  @nigel-skates since all are 1wire senosrs, then yes :) any of these sensors work except you have to make your own cable with the RJ45 connector in order to be used in the hub https://www.unipi.technology/digital-1-wire-c3

  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

  Dear @meethos, all you need is an external relay with 230V capable coil - the HDO (DSM in English according to the wiki) is a 230V AC signal. The relay will then switch +24V DC from your power supply which will go to a DI of Neuron. An alternative way is to use a smart energy meter like this one: https://www.unipi.technology/smart-energy-meter-pro380-modbus-p40?categoryId=16 right behind the main switch and also connect the HDO signal to it. Then you will read all the information which the energymeter provides (like the current voltages, frequencies and total power on all three phases including the HDO status)

  @blacksoll Those products are only temperature sensors. If you are looking for humidity sensor, take a look at our offer of the Sedtronic products: https://www.unipi.technology/sedtronic-1-wire-sensor-p67?categoryId=3 Martin

  @abornand Hi ! I use aeotec z-stick with unipi and pimatic. The pimatic plugin works with neuron too. No problems so far. I control around 11 devices. Althought pimatic is at beta stage, works now for my home automation over a year.

  Hi Jonathan, do you have some touch screen from previous installation, or do you plan to purchase a new one? Generally speaking, the touch screens in industrial automation are equipped with PC (Pro-face for example) running custom HMI software, which communicates with PLC e.g. via Modbus. In this case, you can use Axon with no problem.

  @tomas_hora It really depends on the actual application. I needed to measure 50mm difference in water level in tight space (approx. 30mm x 30mm). So for me, mechanical solution was a no-go, since there are no such small sensors. But for @knebb's purpose, some set of float switches (at the bottom, 1/4, 1/2, 3/4 and at the top) could be easy and affordable solution. I would connect them to a resistor ladder and 10V power supply thus converting the 5 states into evenly spreaded 0-10V which can be directly measured by UniPi's AI input. This could be better than occupying 5 DI inputs, if the number of DI's is also an issue.

  Hi Evert! We only provide official support for using the 1Wire Hub with standard-compliant 1Wire masters. While it may be possible to turn the RPi into one, our Neurons use a dedicated 1Wire master PCB, which in particular is powered via a discrete 24V-in/2-3.3-5-12-24 out PSU. In principle what you are asking to do may be possible, but unfortunately we cannot provide any guarantees or instructions. Perhaps some of our other users here on the forum might be able to help.

  Little update: We had still some work to do on our heatingplant, we had some flow issues to fix to let the boiler do a good job. After we did this, we noticed that the boiler keeps burning on low flame. Even if the setpoint was high, the boiler stays at low flame. We found out that we need to write a value at this register as well: 14 maximum relative modulation level setting By default all values are 0, even this one. When you give customers some advice about controlling their boiler with unipi, you should tell them this: ;) When a boiler needs to be controlled at setpoint: write modulating supply setpoint at register 1 write fixed setpoint of maximum load of the boiler on register 14 (100%) When a boiler needs to be controlled at cappacity: write fixed supply setpoint at register 1 (90°) Write modulating value of requested load setpoint on register 14
