@grovkillen Is your friend referring to this kind of application of basic physics? Please take note that I took shortcuts in the description at the righthand side of the drawing. Waterlevel02 [640x480].jpg 'Devil in the details', but the principle setup is simplicity itself and completely passive/co...

Inserting also Gust-info in the same graph is only confusing. Therefore a separate graph, which is easy enough with RRDTool. piwind2_20190425 [640x480].png The WS7000_anemometer doesn't provide windgust-info (just 'total wind'), therefore 0 in this graph. For the Conrad-anemometer no software yet to...

Ton_vN

Suspicion is just a feeling, facts count ...... But in this case the data & graphs confirm my suspicions: the various sensors have a ;) 'very different' interpretation of the actual winds. For this graph Accuweather acts as ExternalReference, but it's speed-info is surprisingly lower than the ot...

Ton_vN

@Budman Looking at the description of your speedmeter, it could well have inside more or less the integration-circuit which is now on my breadboard-setup: feeding with 12V~24V for strong pulses from the rotator-contact, plus application of some electronics, it is easy to get an output of 0~5V [full ...

Ton_vN

An electronic anemometer for windspeed quite often applies a 4cup-rotator with a contact-closure/revolution between it's interface-wire_A and interface-wire_B. Cleaning junk, as 'left-over' found such a device (without any documentation), and ;-) that invites for experimentation ..... ESP8266_Anemo....

Due to 'strange' behaviourof a setup with multiple sensors interfacing to á WEMOS D1_Pro (and then getting 3.3V from the WEMOS), I changed the setup in such way that for power the sensor-PCBs are now bypassing the WEMOS and running from 5V Power Supply as provided by an addon Power-Shield. The subje...

Ton_vN

Perhaps the following questions are 'experimental', perhaps not? The questions were triggered by the discussion in the previous messages related to multiple sensors connected to 1 processor. Feedback/hints from experience/expert users appreciated. For a remote meteo-setup I would like to connect at ...

Ton_vN

Also looking at ESPEasy and TSL2561. In the Adafruit-info I see that Light and IR can be separately called from TSL2561, but also 'joined' under Broadband and Luminosity. The description in ESPEasy's wiki seems to describe the application of Luminosity. First question Can the Light-, IR- or Broadban...

Ton_vN

Thanks @Sektflasche Instructive reading! Unchanged WEMOS_Pro + TP4056 + Panel + LiOn-battery seems good solution for my first application: read-out of light levels. ;-) No need to work at night, just need to start at dawn, bridge some darker periods during daytime, and fade out in the evening. In th...

DIY is nice & interesting (for technical people) and may save money, but :| sometimes one simply is not willing (or not having the time) to make the effort ...... In that perspective looking for a ready-made solar power supply to 'feed' my ESP8266s. Basic requirements: - suitable for operation o...

Ton_vN

Direct access is better, but if BME280's data on Dew Point cannot be directly accessed, why not use a Dummy Device?
See https://www.letscontrolit.com/wiki/inde ... example.29

Ton_vN

Meteo-sensing is not just temperature, humidity, pressure, wind and rain, but nowadays also more&more dust & gasses. For dust-sensing Luftdaten.info has made a nice setup, even networked, but for gasses a 'simple' setup for 'Citizen Sensing' is still missing. IMHO ESPEasy seems a suitable pl...

Ton_vN

@Shardan Completely agreed. My continued running of the GP2Y10 is just due to curiosity. And ;) a certain laziness, because I have to modify the related webpages if I 'sidetrack' the GP2Y10, to put focus on the SDS011. Starting fresh is easy, but it would be nice to keep the data and graphs meanwhil...

Ton_vN

@TD-er That is not the issue in this thread. I run SDS011 and GP2Y10 side by side (within 10m of each other): see https://www.letscontrolit.com/forum/viewtopic.php?f=5&t=3516&start=10#p27040 The issue is that we cannot see a similarity between the readings from the SDS011 and the readings fr...

Ton_vN

:? Exactly my problem. If I only would know what the device is assumed to be measuring ...... If the GP2Y10-line in the graph would more or less have the same tendencies as the line for SDS011, it already would help a bit, but not even that is applicable. Thinking about possible influences, :idea: a...

Ton_vN

@manjh Exactly the solution I also implemented. See picture and bigger perspective : - a small fan sucks the air through the 'sensor-pipe' My sensor setup is in open air, outdoors, but protected by a box housing. Initially readings seemed OK, but later much higher values for no clear reason: - fan i...

Ton_vN

Puzzled by the readings from the GP2Y10 relative to SDS011.

Anybody able to provide explanations on the 'operation' of the GP2Y10?

Ton_vN

Perhaps interesting to have a look into this thread

Ton_vN

Just a check/question for understanding. The Pulse-Counter-interface of ESPEasy also produces/provides a value Time. What is the content of this value Time? If the ESP8266 is connected to an S0-interface is there any meaningful application of this Time-value e.g. related to calculation of Usage ? Th...

Ton_vN

By try&error found that with WEMOS ESP8266-PCB the pins D3/GPIO0 and D4/GPIO are the best for counter-application with an S0-interface. At the WEMOS PCB these interfaces have internal pull-up resistors of 10kOhm, and therefore usually for these pins no need for addition of an external pull-up re...

Ton_vN

Experimenting with Dust-sensors, in parallel setups with SDS011 and GP2Y10: see http://www.vannwnhzn.nl/Meteo_Dust00E.html Got SDS011 working as expected, but 'puzzled' by GP2Y10. Indoor testing of the GP2Y10-setup showed results which could be explained. After such experience one would expect simil...

Ton_vN

Probably looking at wrong place:
where is description how to merge an ino-file into the ESPEasy-firmware?

Ton_vN

Further improvement by fitting an extra WiFi-AP: cable running from the main router to the AP covers the physical gap between the main router and the remote WiFi-AP => better spatial coverage and less effect to capacity than with WiFi-repeater at that distance 'listening-over-air' to the main router.

Ton_vN

Why 'load' the LAN because of the MQTT-message/pulse? At least the time-between-pulses in that way is (euphemistically) not very reliable information. With some clever rules the ESP can do the job to calculate Power. IMHO, if you want to divide the functionality, it is simpler to have the ESP8266 co...

Ton_vN

Continuous measurement of time between pulses may be a a heavy demand on an ESP8266 firmware, and I doubt the accuracy ........... It is not difficult to get Watts (W) if you have WattHours (Wh): see https://www.rapidtables.com/convert/electric/wh-to-watt.html It only requires a certain mindset &...

Ton_vN

Based on experience with 2*WEMOS almost side-by-side (=1*Mini +1*Pro):
WEMOS D1 Pro + antenna provides gain as expected compared to 'naked/antenna-less' WEMOS.
The extra dBs from the antenna are clearly visible in ESPEasy's Wifi RSSI.

Ton_vN

Certainly helps to reduce the 'problems' by making a preset link in the router between MAC and IP:
thanks for the tip!

Ton_vN

Have done an experiment with several soil sensors, and concluded that with SHT11 with a certain quality you can measure temperature and humidity to a certain depth underground: see https://www.vannwnhzn.nl/esp8266a5_humtemp01.html Empirically proven that prolongued immersion of an SHT11-sensor is no...

Ton_vN

Any chance to see SI1145 included in a next revision of the firmware, instead of ino-file?

Ton_vN

Which mark & model of UV-device?

Ton_vN

After latest update of Domoticz to v3.8734 2 of the connected ESPs cannot be tricked to start again by reboot of the Raspberry-with-Domoticz. The ESPs are not to blame, because in direct read-out I see them happily generating values. ;-) Just a bright flash: check the IP-address on which that Raspbe...

Ton_vN

Possibly a similar issue (but yet without good solution): viewtopic.php?f=2&t=3339

Still searching & experimenting .........

Ton_vN

Performance on I2C-interfaces may benefit from placing pull-up resistors for the SDA- and SCL-lines

Ton_vN

:oops: This message just demonstrates how much time you can spend by a wrong starting assumption and/or wrong information ....... Found time to connect the received SHT11. To avoid conflicts with the OLED on 'real' I2C (and in fact no choice, because then GPIO4+GPIO5 not made available for selection...

Ton_vN

I see a coincidence that when the read-out of the ESPs stops also at almost the same time in Domoticz the operation of certain lua-scripts stops. More reason to look at the Domoticz @ Raspberry3 and not at the ESPs, and to look as in idea 3) whether fitting an extra Raspberry specific for ESP-readou...

Ton_vN

Looking slightly longer, the reason may be simple [but :-( solution may be different story]. For the ESP8266s the Wifi RSSI has some variation over the day, but for the 'weak' ESP8266s the Wifi RSSI is reported to be < -85dB. That may be too low for reliable Wifi-contact with the router in an enviro...

Received an SHT11 in watertight enslosure, with 4 wires peeping out (without any documentation). SHT11.png From descriptions at AliExpress I deduct that following colourcoding might apply: brown = VCC black = GND yellow = Data blue = CLK Viewing the 'standard' I2C-interface at ESP(Easy) I deduct tha...

Ton_vN

IDXes are nowhere doubled.
Restart of Domoticz (such as after an Upgrade) is not a 100% sure remedy for a 'stuck' read-out.
Reboot 'on purpose' sometimes helpts, but not 100% either .......

Ton_vN

In my configuration Domoticz@Raspberry3 as controller reads the ESP8266s-with-ESPEasy. Till approx. 2 weeks ago without problems related to continuity. But now every day (rather randomly) at the side of Domoticz the read-out stops. When directly calling the ESP8266s at their IP-addresses, I get resp...

Ton_vN

Is this new book of any use /value for the ESP8266-Community?

Ton_vN

Perhaps a battery-shield as solution?
The capacity of this small setup probably is not sufficient to drive LEDs&PWM for an extended period, but only to overcome dips in the primary power supply.
If your really desire a battery power supply with 'muscles', then you might look in this direction.

Ton_vN

If setting up an ESP8266 for 4 pulse-counters, which 4 GPIOs preferably to be applied?

@shardan

For dimensional comparison of 'fork'-sensors (purchased vs. DIY) see the pictures and text at the bottom of http://www.vannwnhzn.nl/esp8266a3_humtemp01.html
'Legs' of all sensors shown are approx. 5cm long.

Ton_vN

Simpler (and less effort&cost) to wait for arrival of the capacitive sensor plus SHT11 from China.
After activation of those 2 sensors then 'Fork+DC'-sensor just for experiments & fun.

Ton_vN

For the 'recycling' just wondering whether to revisit this theremin-setup . Within a simple rigid & waterproof holder going into the soil, Pin1 of the fork as Antenna, Pin2 of the fork as Reference/GND. The oscillator located as close as possible near the fork, with it's own simple&robust po...

Ton_vN

Based on your reported experience that AC-application seems to make the difference. ;-) Apparently further thinking along the same lines. After the (negative) experience with the 'Fork+DC'-sensor planned to have an experimental setup with a capacitive sensor and an SHT-sensor running in parallel on ...

Ton_vN

But why is the rain sensor at my parents home working reliable for more then two decades then? Speculation, but probably that rain-sensor is a capacitive sensor with r.f.-variation as measuring principle , and furthermore most of the time the probe-surface of such rain-sensor is dry (contrary to so...

Ton_vN

The concept with 'fork'-sensor is very cheap, but with short life-cycle.
Further search at this moment provides info on 'better' concepts: see http://www.domoticz.com/forum/viewtopic ... 39#p139039
The capacitive sensor with analogue output seems very promising.

Ton_vN

Shardan is right that the application of AC or capacitive measurement surely extends lifetime, but I am more thinking related to the aspect that the metallic parts of the sensor's probe anyway have constant contact with wet/humid soil and that the electronics are located quite near the humid soil (w...
