Hello
Please help me I have 3x smart implant and 6 Pieces DS18B20 temperature sensors connected to it. My temperatures are displayed but after a power failure some values (temperatures from one or all smart implant) are displayed as 0,0 C. After switching off and on again, the temperatures are displayed again - this is done quite nicely.
Purchased original DS18B20 - replaced
Cables to sensors shortened.
For test connected 2Pieces DS18B20 directly to smart implant, result still the same measurement failures.
Replaced smart implant power supply for 24Volt

Even if the temperature measurement from the sensors fails, the internal temperature of the smart implant is displayed.
The unit used is the HC3 lite

Give me some advice. Thank you Richard

Dobrý den
, prosím, pomozte mi, mám k němu připojený 3x chytrý implantát a 6 kusů DS18B20 teplotních senzorů. Moje teploty se zobrazují, ale po výpadku proudu se některé hodnoty (teploty z jednoho nebo všech chytrých implantátů) zobrazují jako 0,0 C. Po vypnutí a opětovném zapnutí se teploty opět zobrazí - to se dělá docela pěkně.
Zakoupen originál DS18B20 - vyměněné
Kabely k senzorům zkráceny.
Při testu připojeném 2Pieces DS18B20 přímo k chytrému implantátu vedou stále stejné chyby měření.
Vyměněný napájecí zdroj chytrého implantátu pro 24V

I když selže měření teploty ze senzorů, zobrazí se vnitřní teplota chytrého implantátu.
Použitá jednotka je HC3 lite

Dejte mi nějakou radu. Děkuji Richarde

I have the same thing, I made a scene where when the temperature is zero on multiple sensors a restart is performed, with a short outage this error occurs, the other option is to add a capacitor to the power supply.

I reported this to support more than year ago, and still waiting.

Write to [email protected], maybe they will do something with it.

capacitors don't work, its not 1-wire issue.
