Hi Howard, In my installation the ntp feature to synchronize time has nerver been a real success, i'm always several minutes late , i tested several ntp servers and it doesn't change anything. Would

Concerning direction, not obvious to get it properly i know. Anyway thank you for the code that allows to handle mutliple hotwires.

Seems to me wind direction with this is impossible. Adding more would be follow the same pattern, trivial.

So great and so nice ! I’m going to order a second sensor and test the changes. I was not sure this feature was possible so I prefered waiting. May I ask a question ? I don’t know the modern

I've never even thought about using it like that but if it works, great. Basically any digital (or "analog" for that matter) pin on the Mega2560, not used for other purposes, can provide the EN and

Guess the following should work. It takes the higher windspeed from the two devices and returns that... //

Yes, it is configured to pin 11, some devices like a Zyxel router dont recognize it as a conecetd device but still works at the configured ip, the results are the same if i config for static ip

Hi Howard, Experimenting the modern device hotwire sensor which is actually oriented east-west in my installation i was wondering if adding a second one north-south would be possible in OCS

I tested to work a stepper motor to open/close roof using the ROR_POWER_RELAY pin PWM to a DRV8825 step pin, i took pin 3 and 5 for dir and en and added digitalWrite code for those pins on Roof.ino

I will come back around to the OCS for a good once over, and when I do things like this will be built-in.

Works fine fine fine, i implemented it for both current and voltage, thanks for your time, congrats for your knowledge.

You did wire in and handle the W5500 reset pin right? Other than that it seems to be an library level or below issue and not hardware I've ever tested the OCS with. We do use the W5500 with somewhat

You could also bracket the analogRead() and averaging code so it runs at a fixed interval largely independent of the MCU frequency, etc. Below is for 1 Hz samples in which case you would probably

To do this well you'd probably want to change some code from WebAjax: #if STAT_DC_CURRENT_ANALOG != OFF f = toDCAmps(analogRead(STAT_DC_CURRENT_ANALOG)); strcpy_P(temp1,htmlInnerStatusDCA);

I installed the USR-ES1 ethernet adapter, it has W5500 chip, works well but i have a little issue with it when conected to any router in DHCP mode (i use "Ethernet.begin(m);" instead of

Hello Howard, im getting very different values for voltage and current reading, im using 2k2 and 220 Ohm for voltage and ACS712 20A (0,1V/A), some instant measurements differs in about 1V/1A from

Good morning Thank you Howard for your answers. I will slow down the I2C bus. Can I go down as low as 10 or 20 Hz ? is there a minimum frequency specified ?

Sorry, glitched on that, it's 20000 Hz.

I2C speed 10000, is in Hz. Weather stuff updates at 32 second intervals. Log entries every 30 seconds are from running averages read from sensors every 2 seconds. Data is pulled from sensors as

One problem resolved ! The Weather Charts are now correctly displayed once I have cleared the browser (Firefox) cache... Now it is time to tackle the I2C bus sensors problem ! Thanks a lot Howard for
