  1. The Smart Implant can have up to 6 temperature sensors added to it, which makes it handy for climate control applications. Here is a guide based on my experience, hopefully it helps you avoid the frustrations I had. 1. Buy the sensors from a reputable source. The DS18B20 is manufactured by Maxim Integrated (ex-Dallas Semiconductor). There are many counterfeit sensors out there (eg Chinese company CXGAS) that either will simply not work, report incorrect readings, or stop working after a short period. If the sensor is built into a probe it can be difficult to determine a cou
  2. Hi, i was just reading the manual and saw that maximum cable length for the DS18B20 sensor must not exceed 3m. Is that really true since same sensors on the UBS can be up to 30m?
  3. HI, I'm in the process of including all my devices back. I have 3 UBS and 2 of them have 4 DS18B20 probes connected. All 3 are including with just the following slaves. I tried excluding and including but not any better. I seem to remember with a previous Fw that if you didnt have any temp probes connected it wouldn't create the slaves but in this case all three are including without issue but just now temp slaves. Do I need to enable them or any ideas how to resolve? HC2 running 4.120 Thanks _f
  4. Hello I connect DS18B20 sensor in a universal module, but don't show temperature sensor, only display move sensor. ANT ..... GND - GND DS18B20 TD - DATA DS18B20 TP - VCC DS18B20 . . . GND - ( - ) P - (+) 12V Can someone help me Thanks Marcos
  5. Hi. All DS18B20 all have unique IDs. Is there a way to see/read out that ID somewhere? ...or is there another way to identify which sensor is which?? "without touching or heating/cooling a specific sensor and monitoring the temperature?" I can not physically get to the sensors which are embedded in the floor! Any suggestions are welcome Thanks Jurgen
  6. Hi, the reported values of my DS18B20 sensors are not very accurate. They are 1.5C° up the reality. When i measure the voltage on TD wire I only have 2.3V not 3.3V as indicated in the universal sensor data sheet. the module is powered 12V 1.5A supply. This device has not parameters to adjust the offset... Thanks for your help.
  7. Dear All, I get a question - can I connect DS sensors as shown on below picture with using USB? Problem is that I get only 2 wires from sensor location to place where I can get UBS device. BR PBr
  8. I found a very curious bug with the ZW5 version (version >=3.2) of the FGK-101+DS18B20 temperature sensor. When explicitly requiring a temperature report [thru "Sensor Multilevel Get" -> "Sensor Multilevel Report" commands], the actual temperature value reported via the ++synchronous++ Sensor Multilevel Report answer is buggy : +/- 0.5 to +/- 1°C random error from the correct temperature value; the variable size of the error is similar to what you would expect using only 8 bits of resolution from the DS18B20 measures. But when the FGK-101 itself sends an ++asynchronous++
  9. Does anybody know the ACTUAL resolution programmed into the DS18B20 chip when inserted into the ++ZW5++ version of the FGK-101 ? The resolution of this chip is programmable at power-on to 9, 10, 11 or 12 bits, giving respectively 0.5, 0.25, 0.125, 0.0625°C increments. With the pre-ZW5 versions of the FGK-101, the resolution was clearly 12 bits, which happens to be the DS18B20 default resolution at power-on. But using the ++ZW5++ version of the FGK-101, with the SAME Device handler, I get DISCONTINUOUS readings, for instance 22.4, 22.8, 23.1, 23.4, 23.8°C, but NEVER val
  10. I've got a Fibaro D/W sensor to which I attached an external temperature sensor Dallas DS18B20 - temperature is changing accordingly - from 12 C to 127 C The sensor gives me a temperature that's higher than expected and it is correctly connected. It's seems that figures are OK when i change decimal point - is it possible? The temperature hold decimals - there should be a comma after the first digit - it's not 52 C but 5,2 C Can I make a VD with proper value ?
  11. I bought an DS18B20 to my Fibaro Door/Windows sensor. And now I'm not sure how to configure The DS18B20 (that's on a cable with RJ12) Can anyone be kind and describe how to use it. External temp sensor and Fibaro Door/Window sensor. I have attached two photos, one how cable connected to the RJ12 and the other one is how to connect to the Fibaro can anyone help me with how to connect the DS18B20 to the Fibaro, where to connect what color. Thanx
  12. Witam, do modułu UBS chcę podłączyć 4 czujniki DS18B20 do jednej magistrali podpiętej do modułu UBS Figaro. Całość zgodnie z zaleceniami chcę poprowadzić jednym, trójżyłowym, cienkim przewodem (typu drut) zachowując topologię magistrali (zamiast niezalecanej gwiazdy). Cała magistrala będzie miała ok. 10m, a czujniki będą na końcowym odcinku magistrali wpięte w nią mniej więcej co 1m. Czujniki jednak muszę trochę dla estetyki i minimalizacji odsunąć od przewodu magistrali. I pytanie zasadnicze: czy będzie poprawnie jeśli do przewodu magistrali wlutuję dodatkowe fragmenty ok. 20 cm przew
  13. Witam! Ma ktoś pomysł jak wirtualkę zmusić żeby symulowała główny czujnik temperatury? Z różnych powodów nie chcę korzystać z UBS, kontaktronów i innych urządzeń wykorzystujących dallasy DS18B20 do pomiaru temperatur. Za to mam wirtualkę która sczytuje dane z czujników innego systemu i ich wyniki zapisuje w zmiennych globalnych. Czy jest możliwość zmusić HC2 żeby korzystała ze zmiennej globalnej lub bezpośrednio z wirtualki jako głównego czujnika temperatury, wilgotności lub światła? A jeszcze lepiej żeby te dane przypisać go konkretnych pomieszczeń. Liczę na Waszą inwencję
  14. I'm having an issue with getting the Heating Panel to work! I have the following modules - 1) Fibaro Universal Module FGBS-001 2) Fibaro FGS-211 Relay Module 3) Dallas DS8b20 Temperature sensor I want to use these parts as a thermostat to control my hot water boiler. (i.e. temperature sensor on the hot water tank, when temperature drops below a threshold (between certain times of the day) the relay will answer the call for heat at the boiler by switching it on) I have added these modules to the HC2 but I am having problems trying to get them to be controlled by the h
  15. I have a Fibaro binary sensor with a DS18b20 connected for reading temperature. I'm concerned that if the temperature sensor gets disconnected or fails the temperature sits at the last read level. This is a problem for me as any heating could remain on if it fails when the reading is low and heat is called for. Is there a way I can I can configure the sensor to fail to a error state, say to 255 deg C? Thanks
