Wemos thermostat, tasmota.

[frank666]

Good morning everyone,
I have a wemosD1mini with tasmota with thermostat function, is set by tasmota console with 6 temperatures during 6 periods of the day and works very well.
I ask, is there a way with domoticz to manage it graphically?
PS I tried to use the thermostat option already present in domotictz but it seems not to know the wemos device.

I use Setpoint timer feature for sending scheduled value to my ESP thermostat:

hi kimot ,
I didn't receive the notification from the forum, I'm replying now.
I ask you , did you use a script to make a virtual thermostat or did you directly configure an idx and a gpio on the wemos?

[frank666]

using the setpoint function and the thermostat script, I noticed these two difficulties:
firstly, the timer function only allows you to refer to a temperature at sunrise or sunset and not to a time of day.
second, if there is a power failure or a restart of domoticz the temperature remains set to the last value and does not adjust until a new timer action .
How could you modify the script below, so that it always updates to the periods set by the timer?

local heating_probe = 'temperatura soggiorno' -- inserire il sensore di temperatura

local heating_unit = 'relè temperatura soggiorno'   -- inserire il dispositivo attuatore

-- Use when a combined sensor (e.g. temperature and humidity) is used
-- Replace in "otherdevices[heating_probe]" to "otherdevices[heating_probe]" by "temp_only" (in the 2nd "if" and in the "elseif".
-- Remove the -- in the next two lines: 

--local naartekst = (tostring (otherdevices[heating_probe]))
--local temp_only = (string.sub(naartekst,1,4)) -- the digits (1,4) do point out what characters of the string are needed.


local hysteresis = 0.1
