that's like a 2 second change. I'll do it ASAP
in the meantime, you can override it using Customizations
in dev11. Max is 45
Brilliant, thank you.
Ah... a problem. It seems the boiler's weather comp settings also limits the value to 30. My automation no longer errors but the boiler puts it back to 30. Is there any way around that do you think?
hmm, not sure. is it similar to https://emsesp.github.io/docs/Troubleshooting/#changing-a-value-works-at-first-but-is-then-reset-to-its-original-value ?
The summer temp setting on the boiler is digital through menus, not a dial (if that's in any way relevant, after reading through the link you sent). Here's a quick syslog trace when i attempt to set it to 40. Anything revealing on the behaviour?

Yes might have needed it. Seems ok now.
PROBLEM DESCRIPTION
The 'Summer Mode' temperature setting in the Worcester Bosch Greenstar Weather Compensation settings currently has an upper limit of only 30 degrees C. When the Weather Compensation feature is enabled on the boiler and the 'Boiler Outside Temperature' thermostat value meets or exceeds this 'Summer Mode' temperature value, the boiler will disable any response to central heating demand - as designed.
The problem (at least for the way my boiler is installed), is that activation of Summer Mode will also prevent the boiler from heating my hot water tank. This appears to be because the boiler has not been connected up to use its proper designed DHW features. These are all unused in the boiler settings. Intead if has a setup which relies on the central heating features and (presumably) some sort of separate hot water tank valve which opens when the Hive Home smart controls demand hot water.
Long story short, the upper summer mode temp limit will mean that for certain periods in the summer, if the outside temp reaches or exceeds 30 degrees C, I won't be able to heat any hot water. The workaround required would be to disable the weather compensation curve feature entirely, which disables Summer Mode.
Could I please have the 'boiler summertime temperature' value limit increased to 45 degrees C?
REQUESTED INFORMATION
TO REPRODUCE
Attempt to increase the 'boiler summertime temperature' value above 30 degrees C.
EXPECTED BEHAVIOUR
Current behaviour is as expected but undesirable.
SCREENSHOTS
Home Assistant automation failure due to Summertime Mode temperatire value limit exceeded:
ADDITIONAL CONTEXT
I appreciate that had the central heating installers installed my boiler to use its built-in water heating (DHW) features to the full, hot water would be heated separately from central heating water. Tbh, I don't know the reasons for installing it this way. Nevertheless, as I see it, increasing the Summer Mode value limit shouldn't really cause any problems.
Note: this Summer Mode feature was introduced to the EMS-Bus Gateway firmware several months ago when I requested that you add support for the official Worcester Bosch weather compensation add-on in this issue I raised:
