One_wire not working after update - unsure what to change

ESPHome
1

I seem to be striking out on this one…I have others that appear to be working but this one after the update REFUSES to detect the temperature sensor since updating

Its on a propane scale that I only pull out in winter running the fireplace and uses deep_sleep so its hard to update regularly. Just updated it putting it out this year for dallas_hub changing to one_wire and no temp sensor detected.

I would try a simpler configuration. After first assuring that the Dallas sensor is properly wired.

  name: fireplace_propane
  platform: ESP8266
  board: d1_mini


wifi:
  networks:
    - ssid: !secret ssid
      password: !secret password

one_wire:
  - platform: gpio
    pin: D7

    #internal: true
    update_interval: 15s
3

I’ll still need a more complex one that will turn on the power-pin before initializing at minimum.

Its wired exactly the same way it has been for the past year or two and was working before the update.

4

Simplify the configuration just to see if the DS1820 is recognized. If not, you may have a bad one or a wiring issue.

Why do you need to power the sensors separately?

5

I’m running on batteries so even though its only like 2mA drain leaving the sensors on that cuts into the battery life drastically when its 2mA for 59 minutes out of every hour instead of fully off while the ESP is in deep-sleep. With it wired this way I can get a bit over a month out of 2 AA batteries.

If I don’t turn on the pin powering the sensors, they will of course not be recognized.

6

Then you don’t have genuine DS18B20. The consumption should be 1mA while measuring and 750nA in standby.

7

I don’t know what it is just for that but I have several sensors that all use power…but it doesn’t need to be any power at all when its powered down. It can’t be any less than 0.66mA for the temp sensor though because the resistors alone will draw power.

8

Of course, but on the other hand, it doesn’t need to be powered down if the standby draw is insignificant…

I’d like to see calculation for that…

9

Ok, so I finally took it apart and jumped so the sensors stay powered all the time, it works fine.

This used to work fine switched power. I want it to be switched power. How do I fix the code so it will work with switched power like it did before the update?

10

Good question. Your log on post#1 doesn’t really match your code at all…
There’s no switch_on, neither delay at early boot and switch has restore mode : always off.
You should verify if D6 is ever turned on.

11

It turns on and the other sensors for weight power up and provide accurate data. Seems to only be the one-wire stuff not working anymore. It has the turn on/off actions in the on_boot and on_shutdown?

Not sure how it wouldn’t match, that’s the YAML that was compiled and installed and the log it printed?
