Ciao, ho realizzato il vostro progetto e funziona molto bene. Ho aperto un sito su Bluehost (sanpelagio.net) e ho una pagina dove posso vedere i dati meteo della mia campagna. Ora sto modificando il progetto per avere i dati da più stazioni meteo e leggerli separatamente. Uso un piccolo modem e il tutto è alimentato da una batteria 12 V con pannello solare. Ciao.

Hi! I need help with this tutorial. I’m using 000webhost for the website and database management. I was just wondering, what index file should I use or if I need to create my own? I noticed in the tutorial that no index file was made, and when I tried accessing the site I get to a page that says I need an index.php file. I’m totally new at this and any type of help regarding this is greatly appreciated. Thanks!

Hi thanks for the tutorial. I think it should be great for what i need to do. I do have a problem with the Esp-chart.php though – after following the tutorial I don’t see anything on my site when trying to access mydomain/esp-chart.php – was expecting to see 3 empty charts but just get a blank page. Can anyone help please? Not sure if i need to change a setting on myphpadmin to be able to see the page. Have typed and also copied and pasted the code but still get a blank page. Thanks in advance, jonathan

Hi Steve.
You can set the ESP32 to have a fixed IP address of your choice (that should be available on your network): https://randomnerdtutorials.com/esp32-static-fixed-ip-address-arduino-ide/
You may also find this useful: https://randomnerdtutorials.com/esp32-set-custom-hostname-arduino/
I hope this helps.

Hello you wonderful teachers. I just made this project as an example so I could learn how to do it. Now I just need incorporate it into my main project which is a hot tub controller using a WT32-SC01 module, four 30A solid state relays – 30A is overkill especially for the lighting but it is easier to order everything the same – a DS18B20 to measure water temperature and my own version of the BME280 using SHT21 and SPL06 sensors I had fabricated when the cost of BME280’s sky rocketed a couple of years back due to availability issues.

Anyhow, the GUI shows the water temperature, air temperature, pressure, and humidity, and has buttons to turn the main, on-spa controller on and off, set the desired temperature and daily running times for the circ pump. It syncs the time once a day and uses the RTC the rest of the time. leaving the Wi-Fi connection free to handle a web page so the full functionality of the unit can be controlled from my iPad, Android phone etc. – I just haven’t got round to that bit yet. All of the various bits and pieces have been researched using RNT and it would have taken my so much longer to write them without your helpful tutorials. Thank you so much for doing it.

Now, the sample code above connects to my Wi-Fi and is given an IP such as 192.168.1.246 however, if our power goes off (which is an all too regular occurrence here in Cyprus away from the coast) this may or may not be the IP it is assigned on next boot and because it is a stand alone unit, I am not able to simply find out the IP by looking at the serial monitor. However, the MAC is hard coded into the ESP32 chip and will not change so it could be used to identify the unit. Ideally, I would like to go onto my iPad or Phone and simply enter ‘hottub’ in the address bar rather than the IP address – even if it never changes, I still have to remember it!

Do you know of any name servers which would work on an internal network and track the IP address of my separate modules? I have two PC’s in the paint shop of a large car manufacturing facility back home in UK. They are air gapped from the manufacturers own networks and connect to the internet using 4G modem/routers. I use noip.com to track the external IP addresses assigned to the routers so I can VNC into the servers using a memorable server name. I am sorry the post is so long winded but I wanted to fully explain my question.

Once again, thank you for all your good work. Stay safe and healthy, Steve.
