Let's Control It

TD-er

The analog input of the ESP8266 only allows between 0 and 1 V, so if you want to measure higher voltages, you should use 2 resistors to make the measuring part fit in that range. For example 1kOhm + 4k7 Ohm in series with the voltage to be measured, with the 1K over the analog input. (voltage range ...

TD-er

I tried it here and it seems to work just fine.
However, the code I run here has the latest fixes.
You can clear the controller by setting the protocol to "standalone".

TD-er

That sounds like a really nice high level way of programming

A lot of reading to do.

TD-er

That sounds like a good addition to ESPeasy, if it really works.
I think it sounds like a valid option, which would likely work on any ESP board.
Of course you can try it yourself and/or create an issue at the github site, or create a pull request if you already fixed it

@vader: It surely isn't a big code change. Discussion about what's wanted is 90% of the work with features like these

For instance how to re-enable the AP?

(that will add another 5 minutes of programming)

TD-er

I know @grovkillen had done some experiments connecting ESPeasy to his projector. So maybe he can shed some light on this. But I guess you will also encounter some issues with signal levels on the device side. RS232 signal levels are way higher than 3.3V, so you'll probably need a level converter to...

NMEA GPS is not that hard to add, since it is just parsing strings up to 80 bytes. But indeed, a simple import is a lot less work to do and maybe even less time debugging :) Glad to see things are getting easier. How well is micropython capable of doing bit-banging with is somewhat time sensitive? N...

TD-er

@vader:
From a security standpoint, could disabling the AP fallback be a good idea. Like suggested in this issue: https://github.com/letscontrolit/ESPEasy/issues/663

TD-er

Make sure the serial port converter outputs only 3.3V. Usually you connect TX to RX and vice verse. But if it isn't working, try to switch Rx and Tx in ESPeasy. What do you want to connect? The NodeMCU alread has an USB to serial adapter included in the board. So you can connect to it via the Arduin...

TD-er

Are you sure it is an ESP8266 and not an ESP8285?

TD-er

Why stick to the build 148, when you can also use the 2.0 dev series, or even the Mega branch?

TD-er

Indeed, adjusting sensor direction and sensitivity of these sensors is something I'm very interested in.

TD-er

What events are this?
I guess a bit more information would be nice.
For instance, what devices do you use? If you use rules, post them along, etc.

TD-er

Hmm, that sounds great and quite quick development as you're already approaching beta status.

I will try it myself also during the holidays. The ESP32's are already "in stock"

TD-er

You seem to have the "B" version of the sensor, which gives a "0" as S-value. Starting version dev-13, this will be supported, but you can also compile a version for yourself if you need it faster. I don't think the new dev-13 release will take long, since the last 2 days, a lot ...

Hallo Martin :) Er zit een Switch plugin (Device) in ESPeasy. Ik heb 'm zelf nog niet gebruikt, maar volgens mij kun je vrijwel elke GPIO-pin gebruiken met een weerstandje. https://www.letscontrolit.com/wiki/index.php/Switch In Domoticz maak je dan een virtual device aan (een schakelaar) en dan zie ...

TD-er

If you run the latest version, you can disable the automatic base calibration of the MH-Z19.
In the Mega branch, you can even use the "unstable" measurements if you like (or need to due to unstable air)

TD-er

I haven't tried yet to get the SDS011 operational.
I know from the BMP280/BME280 that Domoticz is a bit a-typical in what sensor to use.
So if anyone else has any idea on what sensortype to select in Domoticz, it would be nice.

TD-er

I've made a pull request a few days ago, which should fix this: https://github.com/letscontrolit/ESPEasy/pull/639 The fix I made was to call NTP update every time the WiFi connection was made. Of-course there is still the normal update interval. There are also other WiFi related improvements for eve...

TD-er

Nope, the datasheet mentions 3.6 - 5.5V, which starts at >3.3V
So I guess its results will be less accurate for 3.3V

TD-er

The "OLED framed" is a plugin in ESPeasy. I use that one, since it is more flexible in fontsize. Use 1 or 2 lines output in that plugin and you have some very readable text on those small displays. You can even change the font if you know how to recompile ESPeasy. In the ESPeasy v2.0 branc...

TD-er

What voltage do to use as Vin?
I have only used the older (pre B) version on 3.3V, but maybe the newer versions are a bit more specific on the input voltage.

TD-er

I have those displays too. They display only the even (or odd?) lines so they are "compatible" with the 128x64 pixel displays. Adding support should not be too complicated, but there are 2 OLED plugins. OLED and OLED-framed. The second one uses the library maintained here: https://github.c...

TD-er

Does the red light inside the sensor light up every so many seconds?
I never used the version with the external white connector.
Have you also tried to switch Rx and Tx?

TD-er

Hmm, didn't know that feature.
Sounds nice.
Looks like that code is indeed present in WebServer.ino of the 2.0 branch.

As you probably already noticed, I myself have no experience with that feature.

TD-er

Looking at the pinout of the Wemos: https://wiki.wemos.cc/products:d1:d1_mini
Only thing that looks different is that that port has apparently a pull-down resistor. (D3, D4 have pull-up)
Maybe the Wemos dus activate that pull down resistor during boot, which may cause strange things?

TD-er

I think you should rather use something that looks at some MQTT broker, instead of adding functionality like an extra command. Given the limited resources of the ESP, I think it is best to let the device handle all the hardware interfacing to the sensor and let it push the values, instead of doing a...

TD-er

(which reminds me, I still have to finish my code to switch the laser off between measurements) That's exactly what I was wondering... If the laser of the SDS011 was turned off between measurements. So I have my answer now Its lifetime actually would be less than 1 year. Your code update would be a...

Could you try and disconnect the MH-Z19? You connected the CO2 sensor to D3, D4, which I also did on my PCB . But during flash I have to press the flash button continuously, or else it won't flash. I used a NodeMCU, which has a flash button. But the Wemos D1 mini has not. The flash button is working...

Hello, I thought it would be nice to save my 100th post here to introduce myself :) A few months ago, I started looking at those "too cheap to be good" chips, the ESP8266. I already saw a few screenshots of ESPeasy appear on Tweakers.net forum and was curious. Fast forward a few months. I ...

I have done some playing with the RWCL-0516 radar motion sensor myself. They are great, but you have to 'tunnel' them to get a bit directional detection. I used some aluminium soda cans to play with and those also reduced the sensitivity. You have to place some metal (completely closed) in the direc...

You can try to change one existing module. One of the more simple plugins using I2C is Plugin 007: ExtWiredAnalog So copy the file and change all words with "007" in them into some unused plugin number. Then compile and you have added a "new" plugin. After that, start changing an...

I think the advice of itead isn't that bad. Could you try with a heavier load (about 50 - 100 Watt or something like that) if it still is not functioning like it should? It may be that the relais in the Sonoff is not retracted far enough. Also try to listen to the Sonoff if the low power Christmas l...

I just added a pull request to hopefully prevent these issues. I just added a check to prevent connection attempts when the network is not connected. Every 30 seconds the WifiCheck() function is called (did not change this), which will try to connect to WiFi several times. But maybe it never came to...

I have both sensors here (MHZ19 and -B version).
In one system I use these pins:
D5 GPIO14
D6 GPIO12

And in the other system:
D3 GPIO0
D4 GPIO2 (BUILTIN_LED on Wemos D1 mini)

I think you could try D5 and D6.
Are there other plugins active? Perhaps try to disable them, just for debugging.

TD-er

That's another good use case to put some pressure on fixing this issue: https://github.com/letscontrolit/ESPEasy/issues/589
WiFi should be more flexible.

TD-er

As far as I know, only the OLED_framed plugin allows for this.
But that one doen't support the LCD displays

TD-er

Ah dat is ook een mogelijkheid

TD-er

Je zit hier in het RF-link subforum, echter dit lijkt mij meer een ESPeasy probleem. Of wellicht een probleem met de hardware. Weet je zeker dat je de SCL en SDA op dezelfde pinnen hebt zitten als de BME280 sensor? En is die LCD1602 wel geschikt voor 3.3V? Hoe lang zijn de kabels die je gebruikt? He...

TD-er

You already said the internal pull up resistors are enabled. But perhaps also add an extra resistor of about 10k as pull up and a small capacitor (100nF) parallel to the switch. This will make sure the input is not triggered by external sources, or a bad contact in the switch. Something like this: h...

TD-er

The last version of the source in the V2.0 branch will have a fix for this. And this will be released in dev-13. You can also build yourself from GitHub and then also choose the mega branch, which will add even more filtering options. About the ABC. If you just connected the sensor for the first tim...

TD-er

Do you have any special characters in the router's name, or in the password?
There is an issue about special characters not working with WiFi.

TD-er

Maybe the MQTTConnect function should suggest a delay to the MQTTCheck based on the availability of WiFi.

What pins did you use?
And how do you power the sensor (what voltage)?

I brought a new router nighthawk 7000 and set Virgin as a modem new router hasn't dropped once yet Pfft, solving things by buying better suitable hardware which also might solve other nuisances with WiFi, instead of trying to find a software patch to mask the symptoms.

Can you also check with the latest Mega branch from Github? And then select the BMx280 module. Just to optimize 2.0 branch, if P028 now support both BMP280/BME280 should then P030 be safely deleted to save space during compiling? My patch only made it to the 2.1 (Mega) branch, so when the 2.1 branc...

Indeed, better strongly advice to run on 3.3V logic levels and maybe mention there is some debate on whether the GPIO's are 5V tolerant.
The average user of these devices is probably not knowledged enough to know the implications, so better safe than sorry.

TD-er

Can you also check with the latest Mega branch from Github?
And then select the BMx280 module.

TD-er

What GPIO's do you use?
And have you also tested building from the Mega branch?
I changed the BME280 plugin to "BMx280" to support both the BME and BMP sensor.
And also changed a lot about initialization, detection and sampling of the sensor.
They run here for several months now.
