Esp8266 - esp easy
#11
Thank you I've seen some videos on youtube. Currently I don't need the upgrade because I won't go for OTA. Got some Sonoff S20 and their basic function will be switching the relay via mqtt maybe additional http. For this purpose there is enough memory on board and I guess I'll do my own little Arduino sketch and get rid of the esp easy.

Has anyone tried LoRaWAN yet?

@tocan Sonoff is switching from the esp8266 to the esp8285 on some devices like the S20. The esp8285 has build in memory so I guess it's hard to upgrade it.

For me was important the online update possibility and the training to solder because my solder qualities are down under. Unfortunately was haben that I did need a new soldering iron and decide for an offer of the ts 100. Did pay something around 30$.

I was impressed by its quality.

Now this is very cool Cool

 ESP8266 , LCD display like one of these >

And you have a  display costing a couple of beers to carry around! Just needs an enclosure. 

Esp is running easyEsp so simple to set up. Data is feed from Node-red in openplotter. This is just dummy data to see if it works.

 It does!  

Not sure about powering, there must be some 18650 charger chips on ebay for pennies, or a usb power pack maybe..

Have a look in here -
https://www.letscontrolit.com/wiki/index.php/LCDDisplay

So for the 3rd line in the screen in the photo I send msg.payload = "LCD,3,1,Wps=24K   Wdr=55A"  to MQTT topic /Esp1/cmd
https://www.letscontrolit.com/wiki/index..._Reference


With the Esp MQTT set to subscribe to /%sysname%/# (this boards sys name is Esp1) 

So for your barometer you would b=need to strip out the value and insert it into msg.payload.

For example , for testing I have a function node creating random numbers -
Code:
var random = Math.floor((Math.random() * 100) + 1);
 var random2 = Math.floor((Math.random() * 360) + 1);
   msg.payload = "LCD,1,1,SOG=" + random + "Kts  COG=" + random2 + "M  " ;
 
   return msg;

Works great, need to think a bit about power, would be nice to have a power point in the cockpit and down below but also batteries so you could move it around without switching off.

Wow, even one with a little screen!   Not sure those would work with a 20 x 4 LCD screen though, it needs 5V.

Ah, obvious!   Ta, first power board looks very interesting. Could be handy to power the tablet in the cockpit as well.  One downside of living on a boat is finding an address to send ebay stuff to! Wink
