@TDer Understand what you tell, but setting up the required eventdriven task seems a bit beyond my present knowlegde & skills. Then looking at examples usually is a fast lane for learning: could you hint to any applicable example? Considering the background, such event-driven setup may be a real...

Ton_vN

@TDer Thanks for the elaborate explanation! Reading that explanation a suspicion what is the reason of no completed ADC-read-out in my configuration. The present time-setting is 890s of Sleep & 10s of Wake. ADC-interval now set at 60s (as usual & OK for all my continously operating ESPs) the...

Ton_vN

Thinking-out-of-the-Box 1 might seem a good idea, but the limitations of WEMOS D1 cause some headscratching. The digital output of the Rain/Moist-indicator is high or low dependent on the resistance or capacity due to wetness of the sensing-board, irrespective of the operation of the WEMOS. In my c...

Ton_vN

@TDer ;-) So my suspicion was correct, that 'something' was required for the operation of the ADC with ESPEasy having Sleep-function active ..... The ADC (internal) is a bit strange in this as the ADC plugin is not processed while a WiFi connection is attempted. So then it depends on the set "i...

Solved:

Ton_vN

@TDer Your response is not a short a) or b), but if I correctly understand, it is b) with some 'swing': please correct if I am wrong with the 'simple' explanation below. In my example b) the sleeptime is set at 890s, which means that after going asleep, then approx. 890s later the ESP wakes up and t...

:evil: details to be solved Question from previous message still open, kindly requesting hint: how to get the analogue read-out for the rain-indicator? Something with timing required for ADC, or other aspect overlooked? Question on text-interpretation of wiki [because effects cannot be seen due to s...

Ton_vN

@TDer

Thanks for the hint & explanation!
Then remedy seems simple:
just upgrade to latest ESPEasy v2.x 'Normal' release

Ton_vN

Configuration: WEMOS D1Pro + ESPEasy R147 WEMOS at mains-supply. Similar effect observed in a setup with 2*TLS2561+1*BH1750 at same I2C-bus. 1st TLS2561 looking +30 degrees east (from south) and 2nd TLS2561 looking 30 degrees west (from south). Both of them lock at the same time when lightlevel seem...

Not a question on EASPEasy or on RFLink, but related to use of this website. Looked into the FAQs, but did not (yet) find an answer. Sometimes details only visible if you expand a picture, but those details for just general reading not immediately required. Is it possible to insert an pictural attac...

:evil: Devil is in details ESP8266 up and running with ESPEasy_v2 interfacing 4*DS18B20+1*SHT15+1*Rain-Indicator. Solar Supply is continuous by TP_4056, and is sufficient for 24/7 feed of the setup for Operation cycle = Sleep 15 minutes & Processing 10seconds. All well for the Thermo-sensors, bu...

The communication between WS7000-19-'clone' and an original WS2500-receiver has been checked: looks OK Domoticz most probably just shows what RFLinkGateway presents. . Last days with clear-blue sky and plenty of sunshine gave ample opportunity to check the operation of the 'chain' with WS7000-19 => ...

Ton_vN

Addition of a Voltage detector seems good idea:
no run-up of the ESP (if not enough power available) is better than try&error at wake-up.

Ton_vN

Because of it's limitations, the setup with GP2Y10 for me now is playground for experiments. As a companion to the GP2Y10 + BME280 I fitted a gasmeasuring setup consisting of MiCS6814, ADS1115 and LM35. Now testing feasability of heating to get the gassensor in better environment, and as side-effect...

Ton_vN

Got ESP8266 running with the TP4056-PCB in combination with 2* panel 5W5V like in Dave's example. Next is implementation of 'deep sleep' for energy conservation at consumption side. For ESPEasy_v2 enabling 'deepsleep' is by connection of GPIO16 to RST, plus setting values in the ESP_setup_v2, while ...

Ton_vN

Perhaps not the most correct place for discussion for my setup , but at least here a discussion on implementation of the protocol for WS7000/19 respectively WS2500/19. Since a few days a 'lookalike' of WS7000/19 (equivalent to WS2500/19) in test-operation in combination with RFLink_Gateway [version...

Ton_vN

Triggered by your description of the voltage divider, what configuration of processor & board?

Ton_vN

Interesting information. At this moment looking for a sensor to measure Temperature & Humidity in the soil at - 5 cm (or lower) below the surface in my garden. SHT11 - small.png Have some experience with an encapsulated SHT11, which demonstrates that 'drowning' of such sensor is not a good idea:...

Ton_vN

Looking at the 'official' meteo-stations, conclude that temperature is of prime value, humidity less, especially in deeper soil. But humidity is an interesting aspect for the top soil. Therefore now planning for following setup with 1* ESP8266&ESPEasy: - 5cm with 1* SHT11~SHT15 (encapsulated) fo...

Ton_vN

Wondering why you care about filtering delay related to atmospheric air pressure.
Atmospheric pressure usually does not change very fast and a simple Kalman-filter can do the job of cleaning 'twitches'.

Ton_vN

See the 2 pictures. The solar panel is 14cm*9cm. The black box at the back is the junction box for the wiring, filled with a black compound, also acting as glue for the cover of the box: the sun's heat melted the compound, causing drop of the cover.

Larger condensator C1 improves the signals in the analogue circuit feeding WEMOS' ADC-port A0, but with negative effect on the edges of the pulses for interface-port D4. Lessons-learned: With this simple analogue circuit the readings from the ADC are rather ambiguous, without added value relative to...

Ton_vN

@Wiki ;-) Same lesson meanwhile learned: solar panel inside the transparant box becomes so hot that the cover at the panel's backside glued over the panel wiring drops from the panel. Must split the panel (to fit on a plate allowing ambient cooling) and the electronics (in a box for weather protecti...

Ton_vN

@Wiki Sure! Variant with that type of solar panel in a transparant box almost ready to go for the ESP8266 controlling the light-measurements. Variant with such solar panel plus TP4056-board will shift to an ESP8266-application with operation 24/7: need to check on charging & discharging rythm .....

Ton_vN

@Wiki You confirm my view on the matter. In this post the configuration comprises 5 such 'naked' cells (because the PCBs in the lamps went rusty, and the batteries not surviving either). Fans each require max. 100mA and 5V ~12V, ESP8266s far less. My sun-operated fans now being served, and a few mor...

Ton_vN

Agreed. That implies some calculations to determine the layout of the combination of resistor & condensator at the output of the stepup converter: 1) during initial charging of the condensator at the output, the max. current should be acceptable for the converter => max. size of the resistor, re...

Ton_vN

;-) For power the analogue technology has some value (as demonstrated again). Stepdown is easy enough, therefore reconsidering the buffering & smoothing effects of diodes, condensators and analogue power controllers to provide smooth & clean power to the application electronics. This experie...

Ton_vN

'Lessons learned' Checking/applying the hints from the previous messages: 1) my TP-boards have the layout as shown, which might mean that battery-protection etc. is present 2) Voltage to the TP-board shows fluctuations, but Power from the TP-board to the WEMOS seems always OK to feed the 'bare' WEM...

Ton_vN

@TD-er The setup was OK during testing with a 'normal' USB Power Supply at the place of the solar panel, and therefore suspect that the 'problem' is somewhere at the TP-board. In the line from the solar panel the diode is fitted with the intention to protect against reverse currents [regardless whet...

Ton_vN

;-) Sometimes 'little things' block or help. Made a setup according to this diagram . But apparently the margins of my combination of solar panel plus SI-diode resulted in out-of-range (low) input to the controller: many gaps in power supply to the WEMOS. Replacement of the silicium diode by 2 paral...

Ton_vN

Emperically demonstrated in my setup that 1*BH1750+2*TSL2561+1*ML8511 (at A0) functionally cooperate at 1 ESPEasy-Node without problem.
The TSL2561s implemented as 2 separate devices.

Ton_vN

@TD-er All indicated PCBs are supported by ESPEasy in combination: - Lightsensor BH1750 has selection-option for 2 I2C-addresses - Lightsensor TSL2561 has selection of 2 other I2C-addresses - for both sensortypes the output of ESPEasy is (general) luminosity. - UV-sensor ML8511 has analogue output a...

Ton_vN

Hooking an analogue UV-sensor like ML8511 or GUVA12 to WEMOS'A0 is easy. Otherwise, the 'Minor' aspect to be solved is that the standard catalogue of devices in ESPEasy (upto/incl. R147) does not have an I2C-controlled UV-sensor. Candidates with I2C-interface would be SI1145, or better VEML7x. Is su...

Ton_vN

@TDer

Complication of my intended application is that interface A0 is occupied by the UV-sensor.
On the other hand under ESPEasy's SysInfo I remember to have seen a check on VCC:
is that alternatively usable for battery-checking after boot?

Ton_vN

This information which is further explained in this documentation describes various levels of 'sleep' for WEMOS, from 'No' to 'Deep'. With an application script. ;-) Now just the challenge how to make a stand-alone implementation (with ESPEasy?) that 1) if daytime, then 2) every hour (or comparable...

Ton_vN

;-) Simplicity & proven design is best: for the power&processor-setup went for the configuration described in https://www.instructables.com/id/Solar-Powered-WiFi-Weather-Station/ For light-measurement my WEMOS+ESPEasy interfaces 1*BH1750+2*TSL2561+1*ML8511 It works, but as improvement withou...

BME280 and MS5611 measure absolute pressure. If you want to measure the difference in pressure caused by a liquid column, then you need 2 sensors: - sensor A to measure the 'liquid pressure' - sensor B to measure the atmospheric pressure as reference. MPX5050DP as a differential pressure sensor woul...

Ton_vN

;-) Making use of 1 extra component perhaps this is a simple(r) way to get better power supply & charging: 1) power source = 1* solar panel slightly oversized with output > 7V, or put 2* 5V solar panel in series 2) feed panel output to cheap 3-leg power circuit like 7805-regulator 3) feed regula...

Ton_vN

Possibly this booster is better suited to feed the battery-charger, but what is the probablity that the output of the solar panel exceeds 2,5V, but not reaches 5V?

Just a trade-off:
wait some time vs. extra circuit

Ton_vN

@Domosapiens Understood, but with normal daylight the solar panel should sufficiently charge the battery to provide supply during next night and some more time. My first application will be for a setup with light-sensors, which anyway hardly require attention & power during the night ..... First...

Ton_vN

Indeed, IKEA is near, as well as few other possible suppliers. Connections & Polarities all ;) multiply tested as OK. Tend to agree with conclusion: Because Battery + WEMOS 'behave' OK => BatteryShield seems DOA for at least the battery charging circuit. If no battery attached the output from th...

Ton_vN

@Domosapiens ;-) Reading your messge, apparently I have Situation 0: USB-Power to shield => red LED => power to WEMOS & no Power to Battery From your message, I get the impression that my test-setup might be the problem. In this setup the feed to the BatteryShield through it's USB-interface has ...

Ton_vN

@TDer Your response triggers me to reconsider. You are right: ' deep sleep ' is really deep sleep, and no wake-up other than a basic timer deep down in the processor, in no way from the outside world. Perhaps the idea I suggested is more 'light sleep ', reducing the activity of the firmware to a sma...

Ton_vN

@Domosapiens Your message puzzles ..... If the Battery Shield gets PowerSupply through it's USB-interface, then the WEMOS is On, which is OK. But the question is, why is the BatteryShield not charging the battery, parallel to the WEMOS? 1) If the BatteryShield is autonomous, do I need to set 'someth...

Ton_vN

@TD-er The description of 'CPU Eco mode' seems to indicate that the CPU is 'taking a nap' if not requested to do something. Considering 'ECO-mode' I would have a different look at this aspect. Perhaps it is already available somewhere as specific software, but not found: why not install a scheduler ...

In the perspective of independent setup to link WEMOS-PCB with battery 18650/3100mAh and with Solar Panel 5V/5W (all purchased through AlieX), experimenting with a battery-shield for WEMOS D1Pro , but that just raises questions ...... Regardless whether Solar Supply or grid-oriented supply is used, ...

Some more 'analysis' related to the barometric approach for measuring water level. Calculated pressure rise due to water depth/column is approx. 1 hPa/cm. => -0.5m = +50hPa => -1m = +100hPa => -1.5m = +150hPa => -2m = +200hPa During te most recent calibration-run in real weather for my meteo baromet...

A floating disc sounds like a very practical solution for controlled ultrasonic reflection! For the barometric concept a simple, empirical way to quickly check in practise whether calculation and practise are matching: put a BME280 inside a pipe closed airtight at the end of the BME280 push that pip...

Ton_vN

Comparison of the 2 sets of pressure-data is not a big deal; just a little calculation. Need/meaning of BME280_B is dependent on some 'what-if' estimations related to application: 1) if the liquidlevel shifts, how much pressure-difference/cm (to have a reference)? 2) how quick is a 'usual' shift in ...
