Re: Oh no, not the PCF8591 again...

I hope this isn't a breach of forum etiquette, but since I'm still on with the PCF8591, I thought it better to change the title and carry on here rather than start a new thread, even though it is a completely different issue. I've got a PCF8591 set up measuring some voltages from sensors, which I wo...

Finding the time.

I'm wanting my ESP to know the time. I've got an I2C clock chip, which is one option, but it occurs to me that if it's connected to a network, then it should be able to simply ask a time server.
Is that possible, and if so how?

Ah yes.
I've not found the box with the module yet, so not looked at the interface for it. Sorry, I'll let you know in due course. It may be a while: it's dropped off my priority list.
Thank you for the help.

Going to sleep? Or what's it doing?

I have an ESP-01 set up with ESPEasy. I switch it on, log in, no problem. After some time, I am no longer able to find it on the network.
Sleep is set to 0 (disabled).
If I reset, then it comes back online.
What is likely to be the problem?

Re: PCF8591 as comparator.

I'm not seeing the sense in using an ADC when the info about your project points to using a common comparator chip. For example, I would grab an LM393 (or any other single supply comparator) and configure ESPEasy with the Switch Input plugin to read the state. But I want to read the value, not the ...

Re: PCF8591 as comparator.

The plugin only provides simple analog reads of the four inputs. No other functions are supported. That may be true, but in order to read the simple analogue input, the plugin must send a control byte to the chip: I just need to send a different control byte. I may have to hack the plugin to do tha...
