Hi,
I read this about the esp8266 to go to deep sleep and send data to a node.js server
http://blog.hekkers.net/2015/03/01/esp8266-testing-deep-sleep-interrupts/
Is it possible to send data like that to fhem?? So for exampl port 8001 maps to a temp sensor in them??
It should be nice to have an dht22 for that so it sends data every 2 miniutes tofhem to the esp8266 and the rest of the time is goed to deep sleep
you have some posibilities, i.e. connect via telnet to 7072 and "set %device %Value", or you can use the http command to your fhem port. Or you can use the ECMD device which is mor flexible but a little bit more difficult.
regards,
Karl
Hi,
I can't find anything how to http commands should work??
this is something
192.168.180.5:8083/fhem?cmd=setreading%20mayatemp%20state%20T%2020
any idea what i must replace to get above working in this piece, with socket send?
socket:send(""fhem?cmd=setreading%20mayatemp%20state%20T%"..temp.."\r")
but I don't think thats correct?
below original code
serv_ip = '192.168.180.5'
serv_port = 8083
gpio4 = 2
interval = 20000000
ds18b20.setup(gpio4)
function getTemp()
temp = ds18b20.read()
conn = net.createConnection(net.TCP, 0)
conn:on("connection", function(socket)
socket:send(""..node.chipid().." "..tries.." "..temp.."\r")
end)
conn:on("sent",function(conn)
conn:close()
end)
conn:on("disconnection", function(conn)
node.dsleep(interval-tmr.now(), 0)
end)
conn:connect(serv_port, serv_ip)
hello kroonen,
i wanted to try the example, but i got an error in lua (arg wrong range) in
socket:send(""..node.chipid().." "..tries.." "..temp.."\r")
i am using lualoader 0.83 and latest firmware of the esp.

hi koonen,
i have a question about the library ds18b20.
do i have to modify the library (paths and so) or is this just an upload of the ds16b20.lua?
because in the Source of the library. there are ...
-- DS18B20 one wire module for NODEMCU
-- NODEMCU TEAM
-- LICENCE: http://opensource.org/licenses/MIT
-- Vowstar <vowstar@nodemcu.com>

Robin,
I took the file from here

than the ds18b20.lua
Upload the file like the other and than should work
ok, thank you

i think theres somewhere a define for Testtemp
and in lua is: www.local.lan is this correct or have to be a ip adress?
please use the code function (#) here in the forum -editor to paste the code.
Yes sorry the define was missed. www.local.lan is just dummy

Any idea what cause this

Thank you.. Maybe i can transmit now other things than temperature.

Go Robin go.
Und dann alles in dein meintechblog.de.
Großartig diese Seite.
Gruß Stefan
i will test this. i have a dth here, but not today.
@stefan, no i will write a short statement my own blog.
But the interesting part of the 8266 is the sleep mode, because at the moment i takes too much current.
Robin
Yes we must now look at deep sleep, but I think it's not easy on an esp-01. I think needed is the esp8266-12 for that.
Goal: dht22 with deep sleep fully battery powered push data to fhem every 1 minutes.
Hello kroonen,
i used your code in my blog with a few modifications. I hope its okay.

No problem, mostly I also copied from others.
Let me know if it is up for a week or so, to see how stable it is.

Hi,
I'm also busy with the dht22, but the temp and humidity are not stable, any ideas are welcome. I used a dht22 with resistor 4.7k and without, and also tried this schema

Nice work guys :) With your help i've got my ESP8266-201 running. I used arduino to program the ESP8266 instead of lua, and interfacing to the fhem i used your solution. Hat off to Kroonen many thanks.

Hello,
is there a way to use Telnet-port 7270 with user and Password ?
Greetings Christian
Have a look here: https://forum.fhem.de/index.php?topic=55728

Hallo Jörg, (ich probier mal auf deutsch ;-) )
wie geht denn die Kurzfassung ohne 11 Seiten lesen zu müsen ? Ich schicke über den Telnet-Port per LUA direkt auf FHEM, aber der Telnet-Port ist aktuell offen ohne PW. Nun suche ich nach einer Möglichkeit, eben auch User und PW mit zu übertragen.
Hier mal der Codeschnipsel, mit dem ich das schicke:
conn2=net.createConnection(net.TCP, 0)
-- direkt über Telnet auf FHEM schießen
conn2:connect(7072,"192.168.X.XX")
print("Tasterdruck an FHEM gesendet")
if gpio.read(6)==1 then
conn2:send("set WLAN_Testdose on\nexit\n");
print("ON gesendet");
end
Grüße

Hallo Christian,
es ist alles relativ einfach. Du installierst die aktuelle ESPEasy Version und das im Thread bereitgestellte Fhem Modul. In ESPEasy Fhem als Ziel auswählen, hier kannst Du auch User/Passwort angeben und die entsprechenden Sensoren/Aktionen als Device den GPIO zuordnen. In Fhem ein entsprechendes Device anlegen, und schon schickt ESPEasy Daten an Fhem.
Grüße Jörg
Nö,
das hilft leider nicht, weil ich die Software selber programmiere, ohne ESPeasy, direkt in LUA, damit die das tut, was ich haben will, das läßt sich mit ESPeasy leider nicht darstellen...
Grüße
Christian

conn=net.createConnection(net.TCP, 0)

conn:send("meinpasswort\n")
