Relais plus HCS04

#1 Post by olem_de » 12 Nov 2018, 21:48

Hello
I have connected a 5v Relais plus a HCS04 ultrasonic sensor on a Wemos. Anytime the US Sensor is connected i cant Control the Relais anymore.
Does someone has a workaround or hint?

Thx
Ole

or hint?
On a 1 line question?
Here is a hint: description/version/GPIO's in use/Screenshot/connections/ESP type/Relay type/Rules
30+ ESP units for production and test. Ranging from control of heating equipment, flow sensing, floor temp sensing, energy calculation, floor thermostat, water usage, to an interactive "fun box" for my grandson. Mainly Wemos D1.
