[SOLVED] Heater thermostat control

@rossko57
I really appreciate your help. This rule works beautifully. Code is very well commented - I can learn a lot from it. Many many thanks for helping out again :grinning: :grinning::grinning:

Hi,

So far the rule to control heater been working very well, really glad with it.
Couple days ago I added two text items to my sitemap to display message about two control states for other members of my household:

Mode 0 (OFF) no description was needed :wink:
Mode 1 (Control ON) - “Control ON - Keeping Target Temp”
Mode 2 (Bath) - “Bath - Keeping 24°C”

Sitemap

Text item=Temperature_Setpoint_Bath_Mode2_Info label="Bath - Keeping 24°C" labelcolor=["red"] visibility=[Temperature_Setpoint_Mode==2] icon="my_info"
Text item=Temperature_Setpoint_Bath_Mode1_Info label="Control ON - Keeping Target Temp" labelcolor=["red"] visibility=[Temperature_Setpoint_Mode==1] icon="my_info"

Everything was done in sitemap so no items been placed in items

Today I was reviewing logs and discovered errors regarding both text items from above.
Everything works as expected, both text messages will appear on sitemap when switch is in either mode so not really sure why seeing those errors ?
I hope someone with more experience can spot a problem somewhere.

Always worth peeking in the logs from time to time :smiley:

Because … you specified in the sitemap entries for those Text lines to go and look for non-existent Items. The UI has no way to know you didn’t really want it to look for an Item, when you specified an Item.

The quick fix is simply - don’t specify an item. Just leave the item=xxx part out of your sitemap line altogether.

But do consider instead making your line fancier. Maybe have a meaningful item, actual temperature say. The sitemap label="xxx" custom message will override the item’s usual label. You can put a [%.1f] or similar format into your custom label to display the chosen item’s value.

The item that you use for selection in visibility=xxx need not be the same one as in any item=zzz

Thanks @rossko57

Not sure if I putting this together correctly as my sitemap is crashing when saving.
I changed my sitemap as follows:

Item="Bath - Keeping 24°C" labelcolor=["red"] visibility=[Temperature_Setpoint_Mode==2] icon="my_info"
Item="Control ON - Keeping Target Temp" labelcolor=["red"] visibility=[Temperature_Setpoint_Mode==1] icon="my_info"

View of my sitemap with one of the message displayed.

Capture

hum, well in the version that worked (but produced nuisance log entries) you had

Text item=Temperature_Setpoint_Bath_Mode2_Info label="Bath - Keeping 24°C" ....

so I advised

I don’t know how else to put it.

I tried every combination and can`t get it to work sorry :disappointed:
How would you modify this syntax to work without erroring ?

This is my current syntax:

Text item=Temperature_Setpoint_Bath_Mode1_Info label="Auto Mode - Maintening Target Temp" labelcolor=["red"] visibility=[Temperature_Setpoint_Mode==1] icon="my_info"

I don’t knows what is not clear about “leave the item= part out”.

Text label="Auto Mode - Maintening Target Temp" labelcolor=["red"] visibility=[Temperature_Setpoint_Mode==1] icon="my_info"

Now I know what I was doing wrong :grinning: - I wasn’t far off but my solution didn`t worked.
Many thanks @rossko57
