Let's Control It

I'm using a hall effect liquid meter like this: https://espeasy.readthedocs.io/en/lates ... FS401.html

Is there a way to trigger an event when a value has been reached? (eg to stop a pump).

Thanks

Tony

In older builds I may have had the WiFi scan performed async, so it wasn't blocking, but that gave a lot of issues in connecting to WiFi.

Ahhh.....

Do you remember which is the newest older build with async wifi?

Thanks

Thanks. But I appear to have not been clear. I am interested in the time interval between powering the device and being able to execute On Boot in rules. Experiment: On System#Boot Do TaskValueSet,1,1,%uptime_ms% longpulse_ms,2,0,5000 Endon ESP_Easy_mega_20220616_normal_ESP8266_4M1M Jun 16 2022 438 ...

wiredcharlie

So On Boot is not executed until Wi-Fi is connected?

wiredcharlie

That's really useful, thank you. I'm using a late version with rules cache. The overall performance is fast enough. My only concern is the time between applying power and seeing output on the LED display. I think what you're saying is that this is a function of the size of the rules file only, becau...

wiredcharlie

I have a Rules file of 7657 characters - quite a bit of annotation In Devices: 7 segment display 1 wire Temp Switch 1 Switch 2 Reg Level control (for storing value between power cycles) 4 Dummy Devices Also, I don't really understand multiple Rules files. Are they all executed as if they are one file?

wiredcharlie

I have an LED display on my application. When I hadn't written much code, initialization was instant. But as my code has grown there is now a very noticeable boot delay. What factors affect boot time and how can I shorten it?

Thanks
Tony

wiredcharlie

Thanks TD-er!

That was really helpful. Also, by triggering the Monitor instruction after boot, I removed the unintended consequence of pre-setting the switch prior to power on.

wiredcharlie

Have you enabled "Send boot state" in the switch-configuration? Tried that - but thanks :) It is not sure that the Switch plugin or 7Segment plugin are already initialized at the System#Boot event, so you might want to wait a little, ...but I had it displaying something else from On boot ...

wiredcharlie

I have a physical toggle switch as an input. I want to be able to read the sate of the switch onboot. Experiment: On System#Boot do If Pump#State=1 7dtext,On Endif If Pump#State=0 7dtext,Off Endif Endon No output! The switch has no state until it reveals itself by changing state?

wiredcharlie

Nice work!

I have a coffee machine where I used a sort of fuzzy logic approach to temperature control, so I'd really like to try your PID. How did you tune the PID values?
What thermostat probe did you use?

wiredcharlie

Not yet, but I guess it would be a nice feature to setup a "captive portal" which will redirect to the dashboard when available. There is already code for a "captive portal" in the setup phase, to redirect to /setup when no WiFi is configured. So I guess we can add a checkbox to...

Thank you - really helpful

Using MAX6675 with K-type thermocouple, on the Devices page the Interval is set to 1 sec, but the output is quite noisy.

Is it possible to set an interval below 1 sec then do some averaging in the Rules?

Thanks

Tony

wiredcharlie

I did paste from a text editor; but the when I tried on another board, I typed it directly into the Rules - so don't think it's special characters.

I'm using an S.S.Relay to drive a heater in a coffee boiler. The SSR does zero voltage switching of AC mains. I'm using PWM on a GPIO to vary the heater power. I just got round to looking at the PwM on an oscilloscope and I see it is 1Khz!!!! Is there a way to reduce the PWM frequency or a cunning w...

Polarity

wiredcharlie

Yes it is. But what if then flashed up an optional bitmap for an optional period of time? Eh?

Just one further thought. If the splash screen was customisable with a file and a settable time, that would do the trick!

But, no pressure.

There are examples on Youtube of QR code reading from 1.3" OLED - so that bit is viable. And my own experiments with small QR codes on a laptop screen give me some confidence. you can draw the QR code using rules - how can I do this? I have a 1.3" SH1106. There is already code for a "...

I have made a heater controller for an Espresso machine. I have an OLED display and a web interface (dashboard) to set the temperature. My idea is to use the ESP in Access Point mode and show the QR code for the AP on start up. Then, ideally the dashboard would be the default web page. Tall order, I...

wiredcharlie

Thanks for your help. please don't use delay in rules. That's an absolute big no-no. My loop drives a heater. It applies heat for a set period, then waits before checking the effect. The Delay provides a comprehensible way of doing this. I assume the alternative is to break the whole lot up into sep...

wiredcharlie

Thanks for the coding tips - I will optimise it with your suggestions.

But back to the persistent problem - can you see why that won't work?

wiredcharlie

No I didn't forget the endon. :D I just didn't post the full script: On System#Boot do GPIO,0,0 oledframedcmd,linecount,2 oledframedcmd,display,high oledframedcmd,1,Target: oledframedcmd,2,[Set_Temp#GetLevel] delay,2000 timerSet,1,2 endon On Rules#Timer=1 do // Target temp let,1,[Set_Temp,#GetLevel]...

wiredcharlie

I notice you added a comma - but that didn't help. endon is included - puzzled now!

wiredcharlie

That's what I thought, but no result. From rules: On Rules#Timer=1 do // Target temp let,1,[Set_Temp#GetLevel] Log: 4509072: EVENT: Rules#Timer=1,1 4509095: ACT : let,1,Y 4509100: Calculate: Unknown token input: Y = 0 4509106: ACT : let,2,0-33 4509115: ACT : let,3,0-15 4509124: ACT : let,4,0-7 45091...

wiredcharlie

Thanks, that works. But then in the Rules, [Set_Temp#GetLevel] does not return a value.

wiredcharlie

Thanks for that. What would the URL look like to set the Set Level?

I tried /control?cmd=config,3,Set_Temp,SetLevel,89

...but I seem to be barking up the wrong tree.

Help appreciated.

Hi I've made an Espresso temperature controller and need to be able to store the set temperature as a variable that survives power loss. My plan is to use a custom dashboard.esp to set the temperature with a simple web interface. I can't see a way of storing a persistent variable. Please help! Tony

wiredcharlie

Spot on!

Thank you

wiredcharlie

I see a rather puzzling behaviour here. Initial reading is 21.8 which is plausible room temperature. But then if I warm up the sensor, the value goes down!

What am I missing?

Please help!
