My silicone mold got moldy, can I clean it or should I throw it away? Now its time to for the last step, time to wire the relays to the fireplace. The IO module will have a total of 4 wires connected to it: two for +5v and GND from the power supply, and two for the I2C (SDA and SCL) from the Wemos. If used with isolated 3.3V signals, VCC (To the input of the opto-isolator, next to the IN pins) should be connected to the 3.3V devices +3.3V supply.. I have implemented it but have some issue with turning on relays during reset. I tried borrowing my friends new Orbit controller, and amazingly the hammer is gone. Closest equivalent to the Chinese jocular use of (occupational disease): job creates habits that manifest inappropriately outside work, Cooling body suit inside another insulated suit, how to draw a regular hexagon with some additional lines. The schema (name of the sensors) has changed since I originally wrote this code a few years ago. Are your relays high trigger or low trigger? This eliminates the narly mess you see you when would typically have 8 channels of relays. icon: mdi:electric-switch and received an error message: inverted: True Hi! Could you provide me with the code? restore_mode: ALWAYS_OFF You can also try looking at the ESPHome logs when its booting to see if its doing anything odd to cause it to turn on momentarily, although restore_mode should take care of that. I consider this a necessary consequence of having an open mind. If they are low-trigger you can activate the pull-up resistors inside the mcp23017. I created the 8 channels as output switches and for the time being omitted the remaining 8 channels which can be configured as inputs or outputs.
