Hi, Peridot, you have a nice website there .. yes, the openenergiemontitor project leaves almost nothing to be desired

After a long search I found this:

https://forum.creationx.de/lexicon/inde ... erwachung/

Interim status report

I decided to use a "SHELLY" product - the documentation seems better to me
DSCN0577.JPG
The following is the partial !! result for the "ShellyEM" - a module for power measurement with relay output
The red indicator of the power value turns green when the solar system produces more than is needed
Part 1 -reading the AHOY DTU and part two -reading the SHELLY still need to be merged
DSCN0574.JPG
I have inserted the watchdog that often breaks off the connection and the annex-module has to be restarted. I also suspect a defect because that the RSSI value is very high near the router.

sometime later I will have to send commands, so I tried to turn the relay on and off with the SHELLY, but I only had success via the browser command line with:

Code: [Local Link Removed for Guests]

http://shellyem-3494547bb5f5/relay/0?turn=on
DSCN0578.JPG
but all attempts with WPUT or WPOST didn't work - can anyone help me with the syntax?
Just one of many attempts

Code: [Local Link Removed for Guests]

a$=wput$("http://shellyem-3494547bb5f5/relays","0?turn=toggle")
can anyone help me with this????

have a nice day
Ron

Code: [Local Link Removed for Guests]

a$ = WGET$("http://shellyem-3494547bb5f5/relay/0?turn=on")

in this loop:

Code: [Local Link Removed for Guests]

tft.init 1
tft.fill 0
do
pause 5000

a$ = WGET$("http://shellyem-3494547bb5f5/relay/0?turn=on")

pause 10000
a$ = WGET$("http://shellyem-3494547bb5f5/relay/0?turn=on")
html a$
loop
after 1 or two loops i got errors:"No Data. httpCode:-1No Data......"

One more small note: WGET$ also did not work in the other code I posted above to read the data, it only worked with "wgetasync"
And one more thing: when I used wlog I didn't get any data via wgetresult

I must check, the code for WGET$ and WGETASYNC internally is the same ...
