Good day to you all,
I am looking for a thermostat to control my ac unit that
has a simple HTTP rest API that I can issue simple
commands to such as 'http://thermostat?
mode=cool&temp=72'. Through my recent quest with Shelly
units (which I absolutely love!), I spent what seem like
days trawling through unspeakably complicated
documentation with out of date commands to reach a point
where I could simply turn a light on! I am hoping to find
something that has some understandable documentation and
complete local control. I am using Powerhome as a back
end processor to commands issued from a web API I am
writing in node.js/electron. Does such a thing exist?
Thanks,
Phil

Hi Phil,
I also use Shelly devices and love them as well.
One of the problems with the Shelly doc is that there are two different generations of the devices.
That complicates finding the proper set of commands.
For their light bulbs, this may assist you:
the {} are PH global variables that I set.
You can hard code them if you prefer.
for example:
{SH-ADDR_TABLE_LAMP} IP address of the device: 192.168.x.y
{DIM_AMOUNT} your brightness amount (range 0 to 100)
{SHELLY_TRANSITION_TIME} MS of transition time 2500 seems good (range is 0-4000)
{SH-URL_METHOD} I use method 13 (PH setting)
{SH-URL_TIMEOUT} I use 6000 (PH setting in MS)
So a command to turn it on would be:
ph_geturl1("http://{SH-ADDR_TABLE_LAMP}/light/0?turn=on&whit e=2&brightness={DIM_AMOUNT}&transition={SHELLY_TRANSITION_TI ME}",{SH-URL_METHOD},{SH-URL_TIMEOUT})
Command to turn it off would be:
ph_geturl1("http://{SH-ADDR_TABLE_LAMP}/light/0?turn=off&tra nsition={SHELLY_TRANSITION_TIME}",{SH-URL_METHOD},{SH-URL_TI MEOUT})
I'd be interested in a thermostat, but like you, haven't found anything to my liking.
Let me know if you find anything.
Thanks.

Thanks gg, it was actually your original post some time
back that pointed me to Shelly having resisted changing
my ancient but working X10 system for years! I have now
got to the point where I sort of understand the Shelly
docs and am now using chatGPT to write some pretty cool
functions for me!
The only Thermostat that seems to come close is made by
Radio Thermostat, however, the reviews are pretty poor
which has prompted me to seek out other solutions.
Although unrelated, whilst looking for similar HTTP
enabled devices, I today came across a REST API
controlled IR blaster which looks fantastic. Now to ditch
the usb-uirt!
