Let's Control It

GravityRZ

thanks

i am going it only to dim leds so it should be safe

GravityRZ

when switching leds you can use either gpio or pwm gpio,14,0 (led off) gpio 14,1 (led on) pwm,14,0 (led off) pwm,14,500(led on at certain level) so i should either use gpio or PWM but not both for the same gpio pin (unless i reset pwm with pwm,14,0 first) what happens if you use them together eg pwm...

GravityRZ

a workaround is to set avariable each time a gpio changes

Code: Select all

On gpio#4=1 do  
   Publish,MYESP/electrical.chargers.thruster,ON
   let,4,1
endon

then you can check or send it out with

if [VAR#4]=1

or publish .... [VAR#4]

i will try out the new P003 implementation to see if it also solves my problem(extra pulses) as soon as i get a mismatch in my current setup i will flash the new fw quick question at the moment i have set debounce time to 2400ms (maxflow is 24.9 liters so 60000/25=2400ms) when i use the new pulse lo...

GravityRZ

and if you loose the 1k resistor(so basically only connect TX and GND)

also note that eveybody is talking about the RX but this is the RX of the terminal

The meter only has a TX which needs to connect to the RX pin on your usb-serial cable

one mistake which is often made because it is so simple.

GravityRZ

thanks.

GravityRZ

i want to switch multiple leds on/off seperately this is mostly done by hooking up a led with a 220ohm resistor in series between a GPIO port and the ground. When GPIO is 1 current will flow from GPIO to GND (Max current=12mA) When you hook up multiple leds te total current need to be supplied by th...

GravityRZ

and do not forget the 1k between and rx

GravityRZ

that looks right with the following remarks. i do not think you need to feed 5v into the meter. there is always a risk of blowing up things also mixing 5V and 3.3 volt without shielding those might cause problems if it is coming from the same source(the ESP) with my setup the 10k did not work and i ...

GravityRZ

when i first connected my RFXTRX433XL to my meter i did not have any readings either. it turned out that the unit used a 10k pullup resistor which limited the current to much. i replaced it with a 2K2 resistor(as advised by the makers of RFXTRX433XL) and then i got good readings. in my case i got a ...

GravityRZ

i think i let it run for a while. it is still in test setup in my bedroom without any fancy enclosure. Also i am going to add an BME280 (have one already but the module is mounted to close to the esp8266 so temeperate is useless) since we have had really spectaculair weather in the netherlands as yo...

GravityRZ

ok i understand but did not figure the wear would go so fast.
indeed during the day it is around 400.
i think enabling ABC will not help because this will put the level to 400 while it is already 400 at the moment and i doubt the actual level will be lower than 400 at the moment

when i first installed the MH-Z19B is had a range from 400 during the day to 1500 at night.
i noticed that every new night the maximum is getting lower.

does this mean the sensor get's less sensitive.
During the day it is still around 400 so it seems to work ok

ABC is disabled sfrom the start

GravityRZ

good tip, did not know that they are now in the order of happening at bootup (bootup, mqttconnected, mqtt received, pulse counter action) also i mix gpio triggers with event triggers and i know that is not ideal. Edit. i noticed i made a new version to compensate for this new version with both GPIO ...

GravityRZ

i do not have a screenshot of the devices but if you read the code you can figur out what devices are configured en what the variables names are. coding ofcourse could be smoother but i was trying to solve a problem so cosmetics were not my first priority. i deleted the non involved sections device ...

GravityRZ

as mentioned earlier is am trying to solve a problem regarding extra pulses for months. I am now focussing on a solution instead of the problem with good results. Because the debounce time is not perfect i am taking a second step and solved the problem in rules this is a solution for extra pulses an...

GravityRZ

totally clear now and thanks for the code efficiency.

i my mind i was focussed on that interval update speed and thought it would be limiting things but now i iunderstand.

i am not going to feed 2hz in to it but mostly 1/2 Hz at max.

GravityRZ

this is going to be along discussion HaHa. i get most of what you are saying. question let's say i put a 2Hz signal on GPIO14 i create a dummy device on Task 1 (no other devices) interval 1 second What would be the variable update speed of TaskValueset 1,1 What would the gui update speed (variables ...

GravityRZ

but if i delete the pulsecounter device then the interval limit is gone either way and i can feed that same signal into the GPIO14 port. so with only rules in place(no devices/plugins) i can use GPIO as an interrupt and it will react instantly the GPIO level changes and start whatever action i like(...

GravityRZ

from within the ESP i flip a switch in domoticz which triggers a script SendToHTTP 192.168.1.50,8084,json.htm?type=command&param=switchlight&idx=334&switchcmd=On //initiate mqtt broadcast in this script i have this this sends out 1 number which will be received by the MQTT import plugin ...

GravityRZ

The plugin interval settings on the pulsecounter plugin delays the refresh of the plugin variables (eg when set to 60 it sends out the values every 60 seconds) This plugin is using GPIO14 however when i make a rule which act on GPIO14 (On GPIO#14=0 do) this also gets a 60 second interval. i would ex...

GravityRZ

that is exactly what is did. for me it is working but i use only a couple of variables @ _Cyber_ maybe the problem is that you are using variables above 10. i remember reading a post where this was a problem(it should not be) A simple test would be to store the unixtime in a variable, set a timer o...

GravityRZ

that is exactly what is did. for me it is working but i use only a couple of variables A simple test would be to store the unixtime in a variable, set a timer on 1 second and store unix time in the next variable. If the difference is 1, then you have the double feature :) Another option could be to ...

GravityRZ

i am using 20210114 build.

if it is not in that build than i still do not experience problems.
looking at the system variables it seems to store the entire %unixtime% value

GravityRZ

to avoid al these issues with the pulsecounter i am now trying to bypass it totally(only use the time for flow calculations) i use a dummy device and let it trigger through GPIO this way we have a sort of interrupt based counter instead of a 1 second base check. to avoid false pulses i measure the t...

GravityRZ

thanks TD-er

GravityRZ

ok. that post learns me that when i convert a unixtime value (1607951606) to binary i get around 31 bits so unixtime does not fit a variable if it can only hold 22 bits my question however was not if it will fit or not but if it can do these large calculations. i assume that for calculations the ESP...

GravityRZ

i recently discovered %unixtime% and i use this to time things(delta between actions) to be save i replaced it with %syssec_d% but discovered that this value resets every day(duhh) and that was causing other problems to keep things simple i want to do this Let,4,%unixtime%-1613000000 this will give ...

GravityRZ

Nice. i was doing something similar with %unixtime% but did not have any problems at all just to be save i exchanged it for %syssec_d% :D I mean, the value for your dummy-var is to large! I think 65535 is the maximum. Edit: I already see, my post is nonsense... Not entirely nonsense... The limit isn...

GravityRZ

i would love to have this as well
i know somebody made a p222 debounced counter but i never got it to work properly.

GravityRZ

thanks. good info.

this evening i will a window open to see what the max amount of co2 will be.
indeed tomorrow there will be snow so opening windows then is not an option.

GravityRZ

the current P049 plugin for the MH-Z19 has a setting to disable ABC calibration. does this disable setting stick with reboots and power off/on? the reason i am asking is i see that there is an mhzabcdisable command but do not know if this should be used All the info i read dates back to 2017 so it l...

GravityRZ

ok, clear now

GravityRZ

ok thanks.

it boots fine when on D7/D8
i mainly flash over wifi but still if i needed to flash using the serial interface i would not like it to detach stuff

for now i will leave it on D7/D8

any thoughts on hooking it up to serial1?
what is meant by connecting it to -

GravityRZ

finally got my sensor in after 2 months waiting currently havre i thooked up on D7-D8 an it seems to work 2 questions is hooking it up to D9-D10 better? i also see i could connect it trough I2C but as far as i can tell the MH-Z19 does not have the necesarry connections Any idea on to connect it thro...

GravityRZ

@TD-er, can you have a close look at the new Time implementation.

if this changes from total time between pulses to the time a pulse are high it will render the complete watermeter flow functionality useless

GravityRZ

interesting. The modified pulse low and pulse high might be a good implementation as long as the debounce time really blocks every pulse which is faster than the debouncetime.(so not once but always) and does so acoordingly to the type you have set(pulse high or pulse low) regarding the time modific...

GravityRZ

ok thanks.
i thought so since the timer did already ended

clearing up the rules

GravityRZ

thanks.

changed the code so i can only check on 1 variable [VAR#2]

GravityRZ

not sure if this works

i know i can compare 1 or multiple variables but am not sure if i can do calculations

on MQTT#value do

if [AAA#Total] - [BBB#Total] =1
do your thing
endif

Endon

GravityRZ

i am using a timer to reset a value to zero if XXX is not called then the timer will not start again My question since the timer will not start again is there any reason why i should use the timerSet,1,0 in the Rules? eg can i delete it? On Rules#Timer=1 do TaskValueSet 3,2,0 timerSet,1,0 EndOn On X...

GravityRZ

UPDATE: eveything seems to be working after all important to mention is that if we use the values combined then we MUST USE #All aparently the #Count, #Total and #Time do not work to trigger events So in my code i needed to change Watermeter#Count into Watermeter#All On Watermeter#Count do // When P...

GravityRZ

thanks. the second on Watermeter#Time was only added to see if i can spot an anommaly (very low time) normally i only have 1 on Watermeter event and with that one i still get extra pulses. regarding your extra functionality. 1 event only has one %eventvalue%, this is the reason i masde the second ev...

GravityRZ

looked at the timimgstats but do not know what to look for. i attached it regarding the queue i only had 1 On --Do command which was active on a 1 second base. i now added a second one to record possible low timings and store it in Maxflow for the time being if i record a reading lower than 2000 and...

GravityRZ

@TD-er i let this one run for a very long time but i still get some extra pulses some time. to make things easy i use the direct numbers from the pulsecounter itself eg. the Watermeter#total is the exact watermeternumber which i set with SetPulseCounterTotal so if here is an extra pulse we know for ...

GravityRZ

ok, will check that.

GravityRZ

i have a new router which has a bit less range than the old one. because of that a Wemos D1 mini module which is on the second floor sometimes disconnected and connected again (-80DB signal) i replaced the module with another one but the problem remained(wemos does not have a good wifi antenna) no b...

GravityRZ

ok, i have regular esp units so we can rule out hardware

i will monitor this as well and get back after 25 days

the unit with the pulsecounter seems to work at that time because it was still sending out pulses.

that unit is set to wifi no sleep so this affects the functionality in a positive way

GravityRZ

i was using 20200812 firmware for 25 days without problems. yesterday i noticed that the esp unit stopped updating 2 temp sensors(Environment - DS18b20) and a barometer sensor(Environment - BMx280) it was accessable thruogh the browser but just did not update the sensors. a reboot fixed the problem ...

GravityRZ

ok. it seems that after running stable for so long i tried to looosten up the settings i apparently changed the wifi no sleep after setting wifi to no sleep again the system seems stable also with the 20200426 build. it seems that this one setting can cause extra pulses could it be that some way whe...
