Wall Display Webhook

Pierce Maher

Wall Display set up as Thermostat

Firmware 1.2.5

I have a moterised valve which is controled by Shelly 2PM

Action 1 Tempriture Change (Measurment)

Then Send http://192.168.1.XXX/relay/0?turn=on

Action 2 Tempriture Change (Measurment)

Then Send http://192.168.1.XXX/relay/0?turn=off

the Shelly 2pm does not open or clos the Moterised valve.

If I Use a web brouser and send http://192.168.1.XXX/relay/0?turn=on

it does turn the valve on and off ok

Webhook does not apear to be working correctly with the wall display

I have several Wall Displays which I have set up as Thermostats and have configured

it to send a Webhook command to tur on and off another shelly unit.

I can not get this to work reliably.

Does any other user have a Wall display that can turn on and off another shelly unit using Webhook

Can I ask why you use a web hook.

As you can do this with out using a web hook. The way I did it with my Wall Display was to set it up as a thermostat, select the temp sensor to use, then select the actuator. No need to send web commands.

If you have already set up a thermostat in the Wall Display then just edit it and go through the options Main, Sensor and Actuator, select the required actuator. I then set up 4 schedules On at 07:00 and Off at 09:00 then on at 18:00 and off at 23:00. Seems to work, I only set this up about three hours ago (time now 22:47), but so far so good.

After a day of testing

Schedules are not working. Other than that I can get the wall display to control a plugin module that os attached to my electric radiator. But as it says its in Beta so hopefully a new firmware update will solve the many issues.

I deleted the thermostat I had set up.

Ok not too sure what was going on but I then set up the thermostat again, this time I could see the heating schedules so added them. Last time I just added schedules via the schedule section in the menu, not via the thermostat section.

I also noticed a new firmware update so updated. I am now on 20231213-155002/1.2.5-4336d946-hotfix3

So in theory the wall display is now controlling a Shelly Plug V2 which it seems to be doing during the specified times.

So hopefully it should now work.

I purchased one Wall Display unit and after testing purchased several units for a project we are working on. We originally proposed to have these units control several shelly units using Webhook

Commands after a lot of testing we discovered that using the wall display units to send Webhook commands didn’t and we provided support with detailed logs. They suggested that we update The Shelly 2pm which were receiving the Webhook commands to the latest software which didn’t fix the problem.

Following a user suggestion we set up One Wall Unit as a thermostat, select the temp sensor to use, then select the actuator.

This worked for the first unit so we started to program all 8 wall units to control 4 2PM units as actuators.

We ran in to further trouble some units worked and some didn’t after many hours of configuring and changing we established that the Wall Units could only address the 0 channel on the 2PM and if it was configured to control channel 1 it controlled channel 0.

It is now odious that the Firmware for these Wall Units is not fit for purpose has not been tested correctly and has multiple errors.

When do Shelly propose to have usable Firmware available for these Wall Units.
