I've taken a look at your extension, and I've been able to replicate the problem.
You are defining some new types (such as 'uptime', or 'linkUptime') that are assigned to group_deltatime, which is a perfectly reasonable thing to do. The problem is that there is no 'context' to go along with them to specify what string format to use, which causes the TypeError. This is a use case that I had not anticipated, although I really should have. I had assumed that members of group_deltatime would always be generated programmatically, not from a database. In retrospect, a silly assumption. I've done a commit to supply a sensible default context if none has been supplied. Commit 279bb45 <https://github.com/weewx/weewx/commit/279bb450ab801c80a12b8ceadd0144e16c473bea> . Here's the patch: Index: bin/weewx/units.py =================================================================== diff --git a/bin/weewx/units.py b/bin/weewx/units.py --- a/bin/weewx/units.py (revision ce49dbdf5d9125550594e3ba58ebbfc0a67073ea) +++ b/bin/weewx/units.py (date 1644711155863) @@ -741,6 +741,8 @@ elif val_t[2] == "group_deltatime": # Get a delta-time format string. Use a default if the user did not supply one: if useThisFormat is None: + if context == 'current': + context = 'delta_time' format_string = self.time_format_dict.get(context, DEFAULT_DELTATIME_FORMAT) else: format_string = useThisFormat If the default delta time formatting doesn't work, you can supply an explicit formatting. Formatting for delta times is a little different from regular types because interpolation must be used to cover all the different parts of the string. For example, instead of $current.linkUptime use $current.linkUptime.format("%(hour)d%(hour_label)s, %(minute)d%(minute_label)s, %(second)d%(second_label)s") or $current.linkUptime.format("%(day)d%(day_label)s, %(hour)d%(hour_label)s, %(minute)d%(minute_label)s") Hopefully, you get the idea. To get you going now, you can either supply the patch I included above, or you can use explicit formatting. Either will work. -tk On Sat, Feb 12, 2022 at 2:55 PM 'Werner Krenn' via weewx-user < weewx-user@googlegroups.com> wrote: > vince, > > see https://github.com/WernerKr/weewx-davishealthapi > There is no > ...
