Witam mam problem z blynk. Problem polega na tym że jak jest przerwa w dostawie pradu i po ponownym wlaczeniu prądu przekaźniki samoczynnie uruchamiaja się i np zapala się swiatlo. Kod standardowy esp. Plytka wemos d1 r2.
Hi, I have a problem with the fluid. The problem is that as there is a break in the power supply and when the power is switched on again, the relays automatically start up and, for example, the light is on. Standard code esp. Wemos d1 r2 plate.
potrzebuje trochę więcej szczegółów - używasz pinów cyfrowych czy wirtualnych? Czy odtwarzasz stany pinów z serwera po powrocie zasilania -Blynk.syncAll() ? najlepiej wkleić kod lub link do kodu wtedy analiza przypadku jest łatwiejsza
a tak btw zapraszam na blynk.pl - staram się tam po naszemu opisać działanie BLYNKa
lub pisz na blynk.pl@gmail.com

Need some more details - are you using digital or virtual pins? Do you restore the pin states from the server when the power returns - Blynk.syncAll ()? The best way is to paste the code or link to the code then the case analysis is easier
and so btw I invite you to blynk.pl - I try to describe our BLYNK’s work there
or write on blynk.pl@gmail.com

Hello and welcome to the official Blynk forum. If necessary please use English translation, as that is the predominant universal language used here. I have added Google Translated text for the benefit of other users reading this.
Your issue is either due to the normally pulled HIGH pin state of some ESP dev boards, and/or your relay is one of those that triggers ON with a LOW signal instead of a HIGH signal. Try a different pin or immediately pull the necessary pin LOW (or HIGH) in your sketch startup. with pinMode().
Hi fellows I have the same problem as the companion tomixps.
I have configured two pushbuttons on the digital inputs 8 and 9 whenever I connect power is connected to the D8, and tested on different digital inputs and simpre same as the first is powered alone.
it is solved by changing the relay system.
that operate with an opto-coupler
Relays that only work with transistors work well do not operate when you connect power
