It has very limited resources, which makes also implementing security a bit of a hassle. And also it is harder to update all appliances with new firmware to update for security. These...

I think the entire web-interface would benefit from a good redesign. Would it be good enough if you had a single link to open that command page? Not to clutter the top bar too much, but just to allow quick access to certain sub pages. I always like the "basic"/"advanced" approach...

What version binary did you use? Or did you compile it yourself?
If I remember correctly, these Sonoff's have 1 MB flash.
Not being able to save the settings, may be the result of incorrect settings of flash size.

Don't worry, with that speed at the moment all bugs will be fixed until 2050.... or not.... :lol: Well bugs are fixed quite fast at the moment, only problem is "you" -users who find bugs- outnumber the bugfixers ;) And Christmas holidays are coming, which hopefully gives a bit more spare ...

Where should %value% come from? What is its input? Normally, you should include the devicename and parameter name, but what should you expect?

Like I posted also elsewhere here on this forum today:

In the Tasmota issues some reported something similar: https://github.com/arendst/Sonoff-Tasmo ... -342000029
There was suggested to add an extra 400V 1nF capacitor.

Does that photo match your Sonoff's?

TD-er

Try to power the Sonoff only by using the programmer. Just to see whether the power supply of the Sonoff might be causing an issue.

And what voltage does the programmer give on the V+ pin?
If that's > 3.3V, then you may kill the ESP device.

How are you going to connect the 5 relais?
Finding 5 free GPIO's is already hard and then you also need one for the 1-wire.

I never tried to write things from external source to the display. Please note that the OLED and OLED framed plugins are very different in how they work. Just looked at the sourcecode of both. The Framed plugin only seems to accept the "OLEDFRAMEDCMD,On" or "OLEDFRAMEDCMD,Off" Th...

The 1.3" OLED probably has a SH1106 chip and not the SSD1306. I've built in support for that chip, but that is only merged into the "mega" branch: https://github.com/letscontrolit/ESPEasy/pull/509 So it will not be in the 2.0 release, but you can use it if you build the Mega branch. I...

But still it makes more sense to have "Bedroom_light" and "Bedroom_CO2" etc. instead of "Bedroom_4" and "Bedroom_3", since #2 was already used in the hall. and #1 in the livingroom. As I understood, the unit number must be unique. And I wonder what the maximum...

TD-er

Are you sure you cannot change the unit name (and thus the hostname) to something you choose? I have several devices running here at the latest version of the code (somewhat) At least newer than the dev-12 build, and they do not have the numeric padded after the unitname. Edit: After posting, I thou...

I've noticed the same.
Do you have similar issues as I described here: https://github.com/letscontrolit/ESPEasy/issues/594 ?

Zwave is using 868MHz, Wifi 2.4GHz. So in theorie wifi should operate better in a wall then zwave due to the shorter wavelength. Zwave is working just fine at my home, so wifi should do better.

Shorter wavelength depends more on a "line of sight".

As an idea, if you need to have the relay on a different purpose than switching mains, one can cut the traces to mains. On a Sonoff you can't, since the power supply for the ESP part is drawn from mains. On the little device in this topic: you don't need to, since the relay will only be used for sw...

When the old modem (WiFi access point) cannot be found, it will switch into 'access point mode' which will be called "ESP_easy_0" or something like that. Then you connect to it via your phone with default password: configesp Then you should be able to connect the module to another access p...

Hm..... I'd suggest some changes if i understand the schematics right :) - Two SSD1306 Displays - as far as i know it does not work as the display plugins for LCD and OLED can't handle two displays even with different addresses. I don't think there's a fix for that, it will need a massive rework of...

The Fritzing file is also included in the link I gave, however, I used Fritzing only to generate the PCB. It generates a schematic rev 2 rev 3 , but it isn't nice.

I assume you are using some transistor to operate the relais? The output of the ESP is not powerful enough to directly operate the relais. And do you have a diode over the relais? (to protect the rest of the electronics when working with coils) Can you measure the Voltage on the relais coil, with a ...

TD-er

@Domosapiens. Just make sure you don't "reken jezelf rijk" ;) (Dutch for over-estimating things) The power consumption of a pump is quite hard to measure, since its cos-phi is almost never equal to 1. In other words, when measuring with a clamp, you have to take the Voltage into account or...

3.3V would not be possible anyway since the MH-Z19 needs at least 3.6V and the MH-Z19B 4.5V.

They do work at 3.3V, but as I said, no idea about the impact on accuracy.

TD-er

These sensors give AC voltage so direct connection to the ESP is not a good idea. Worse, it is ac voltage - so direct rectifying with a diode won't work properly. Even schottky diodes have a voltage loss. You can make it work with a rectifying amplifier (Operational amplifier with diodes) See wikip...

TD-er

Do these sensors output a DC voltage? Or is it AC? (looks AC to me) If AC, then it will be quite hard to measure directly from a ESP chip. I guess you would need some external circuit to sample the AC voltage, determine Vrms and let the ESP then read that value from there. Also a 0..1V signal in AC ...

TD-er

Well it is probably a bit too time consuming (for the CPU) to run a continuous scroll of values. In the OLED1306-library the image has to be rendered before being pushed to the display. So I think (not tried it) there will always be a delay noticeable between updates. Also the rest of the system wil...

This SCT013 sensor looks like a clamp sensor. So there will be no big currents through the sensor itself. It is working on induction. According to this link , the current through the sensor itself is 0.05A when the current through the measured line = 100A. However, it looks like a AC sensor, so make...

TD-er

What voltage are you using for the sensors? 3.3V or 5V?
I know the MH-Z19 takes more time to performs the measurement when using a lower voltage.
Perhaps this voltage-/timedifference also affects the accuracy?

TD-er

If communication is tunneled (e.g. via VPN), it may well be the MTU of 1500 is somewhere exceeded.
So lowering it to 1400-something may fix it, but it is an indication of the source of the problems.

TD-er

It is remarkably cheap to create some specified CO2 conditions using chemicals. (given you do it for batches of sensors at once) But the problem being faced here is that the MH-Z19 sensor's baseline calibration will be affected by several parameters like temperature and humidity. Also the automatic ...

TD-er

You should set the 400 base calibration in the same environment, as you normally use. Currently outside is humidity and temperature different from inside use. This will have impact on both sensors and both differently. You can let both sensors perform an automatic base calibration, but then please u...

I do not understand all that doing. Before fixing all the known issues, the devs start working on implementing new CPUs like ESP32 and whatever we normal user don't need (yet)!

TD-er

If the new sensor has not been running for 24h yet, I would suggest to disable ABC. Then you are using the factory calibration. And running outside is not the best way to reset the baseline. Internally the sensor stores its calibration value along with the temperature. Perhaps to compensate for some...

TD-er

First try the suggestions already mentioned by Shardan.
And then try to twist the wires to the sensor.
Just like the cables in an UTP network cable.
The twists prevent the cable from acting like an antenna and picking up all kinds of interference.

TD-er

Did you also try to disconnect the sensor for a while and then try again? (and/or reboot the ESPeasy)

TD-er

You can also try to log the system value rssi and see if it shows some fluctuation in reception. What Grovkillen is suggesting is also very good for diagnostics. If the module is not reacting to ping, it is an indication the connection is lost. But also it may be the sensor has crashed. Does the sen...
