'Target Temperature': characteristic was supplied illegal value

[MikeMighty]

Hi there,

Not really a master or king with the codes. My homebridge works without issues, only the following gets spammed in the log:

[8/30/2021, 10:43:32 PM] [homebridge-evohome] This plugin generated a warning from the characteristic 'Target Temperature': characteristic was supplied illegal value: number 5 exceeded minimum of 10.

Can or should i do anything about this?

[luc-ass]

That's a new one... I haven't found similar stuff in my logs. Anyone?

As an Explaination: It seems, that homebridge is not fond of accepting temperatures below 5 degrees. This is used as off in homebridge-evohome. Are some of your thermostats turned off? Can you set them to 10 °C and keep an eye on your logs?

[MikeMighty]

Yes, that seems to solve the problem. I had the system in off mode for the summer. The standard 5 degrees in off mode cant be set to 10 or higher it seems. So the only workarround is to not put evohome in off mode.

Thanks for the reply.

[luc-ass]

Okay, now that we know what causes this bug, can you give me some context?

• Hardware you are running homebridge on
• OS and version on your system
• NPM/Node version
• Homebridge version
• Plugin version

[Barloew]

I get a similar error in my log:

[homebridge-evohome] This plugin generated a warning from the characteristic 'Current Temperature': characteristic value expected valid finite number and received "NaN" (number). See https://git.io/JtMGR for more info.

I am running Dockerized Homebridge on Synology hardware. Alpine Linux (3.12.8) Node.js v14.17.6 Npm v6.14.15 Homebridge v1.3.4 homebridge-evohome v0.8.4

in my case, I have two thermostats at 5°. This has never been been an issue before. What was new is that one of my thermostats ran out of battery. This thermostat created a log file entry with a temperature of undefined°. As soon as I replaced the battery, the issue was gone.

Hope this helps. Thanks for the great plugin.

[luc-ass]

As a workaround you can set your system to "away" and set away to something like 12 degrees...

[MikeMighty]

Hardware you are running homebridge on: RPI3
OS and version on your system: Alpine Linux (3.12.7) 
NPM/Node version: v14.17.5 
Homebridge version: homebridge-config-ui-x v4.41.2
Plugin version: homebridge-evohome v0.8.3

[PuzzledUser]

FYI, I produced this error by setting OFF on the HEAT, COOL, AUTO control. My system has a configured min value of 10°C, hence it complained when 5°C was selected. Shortly later it noticed that 10°C was set as target. No great shakes...

Okay - I tried to reproduce the error but got only valid responses. Could one of you check out the latest version and check wether it still produces the error?

[SeaneyC]

I messed about with various combinations of 15, 10, and 5 degree settings with away turned off and on, and wasn’t able to generate any errors like the 2 users above

My bad. I tried with the system in off mode again with the default of 5 degrees and also bumped it to a default minimum of 10 degrees in off mode on the controller and still wasn’t able to get it to produce anything errant despite playing with Heat/Cool in the Home app and changing target temps (which just get reset to follow the schedule, except then that Heating Off is true so everything is just set to 5 degrees as the target.)

This will set master bedroom to then just follow the schedule no matter what was previously configured (eg any permanent or temporary temperature settings set on the evohome controller or app) and when heatingoff goes back to false, the thermostat will fall in line with the schedule set on the controller.

Okay, thanks for your vigorous testing 😄 @MikeMighty do your run your Homebridge in DEBUG-Mode?

[PuzzledUser]

I tried what proved it previously and there is no error today. I reckon it was to do with OFF setting target to 5°C which is less than my minimum, but it's ok today.

Then I tried a slightly different sequence in DEBUG mode and oops.

To reproduce I:

• Set Off mode in Home
• Set Away mode in Comfort app (NB my minimum is 10°C)
• Opened Home app to trigger error (I guess it reads current state)
• Then cancel away mode (and increase target to above 10°C) to stop the error appearing.

The issue is not dependant on DEBUG mode, just that awkward sequence.
